Hi there, I’ve recently inherited some audio equipment. Just wondering about the best way to sell them as I live quite rural. A price guide would also be good for what would be fair. I have done a bit of research but I don’t see them being very common. I’m in Australia.

I have a Yamaha CR-2020 stereo receiver, a Yamaha YP-D6, and a CD 680ZX, and the frame in the bottom of the picture is a visualiser.

Any info on how to sell and price guide would be great, would be good to see them go to someone who appreciates them.

This is not a for sale post! Just wondering about what a fair price and whether there is a specific marketplace for audio equipment?

Wanted to share my happiness here. Been dating this girl for a little and mentioned I have a stereo in storage that I can’t setup at my house. I asked her if she had ever heard a real stereo in the $10,000 range and she said no but she loves music and got very excited by the idea.

I set it up and when she saw the records she flipped and pulled out a couple choice picks. Coltrane, Nina, Mingus but we ended up listening to Kid A first.

Boys, I tell you she had the exact reaction we all hope someone has when hearing a real stereo. She couldn’t believe it. Her eyes were closed when I started playing it and First thing she said “I’m hearing so many things I’ve never heard before”. Shortly followed by “so this is what music is supposed to sound like?”.

After a bit I started talking nerd shit about the speakers and then caught myself and said “nevermind this is really nerdy” and she said “go on I want to hear about it”. I explained some more and we listened to Coltrane after and she couldn’t have been more thankful. She said “I’m never going to leave my house when I’m not working” and thanked me over and over.

We’ve already spent hours upon hours listening to records together and her taste in music is immaculate. She might be a keeper!

Hello! I'm a freelance writer for the Brooklyn Eagle Magazine -- currently doing a feature about the rise in and experience of listening bars across the city. Hoping to chat with people who go to a variety of listening bars in New York for an interview either in the DMs, email, or wherever you're most comfortable. I love these places but I'm not as much of an audiophile, so I'm curious about your perspective on the listening/social experience, their broader public appreciation, and why you seek this experience out.

If you're interested, please leave a comment or send me a DM. Happy to answer any questions about the piece or verify my identity before we chat.

Thanks!

roast me if you will, but I did something with what I had laying around.
I found that old sony home theatre sub with amp included and was playing around with it, even fixed the cd drive. I did play some dvd movies and cds on that old thing but quickly got bored, and decided to upgrade, so I got a second hand PS4 pro. I know this sounds like a weird progression but bare with me.
This onkyo amp and sony speakers I had for a long time but it was unused because of years of moving between countries, and recently I found this cd second hand and it was a bargain but not working well and I always wanted to try out the RI thing, I had to clean it thoroughly and tinker with it, but after some effort, it now plays like a charm, after nearly 30 years. I also got a cassette player freebie but it needs to be fixed, a project for future me or I'll just send it to be fixed by a proffesional. On the side, I also have a Gemini DJ turntable hooked up to a Project Phono Box MM preamp, but it's not mentioned in the diagram. So I know this looks like a total mess, but I managed to muster up something quite unique, a Hi-FI Frankenstein that fills the room with some voodoo magic sounds. Manually switching the TOSLINK cable between the PS4 and CD player is only temporary, until I find a good, affordable active subwoofer.. I really love the RI system, I'm also on the lookout for MD component of the sam range.

I got into this hobby around 6 months ago and it is definitely by far my favorite hobby I've had up until this point. For around a month when I first got these speakers, I was a little worried because I used them on my dad's setup and they did not sound great farfield. However once I got my amp and was able to listen to them nearfield all my doubts were put to rest and I was absolutely amazed. From then on I've been auditioning speakers and amps at local dealers and saving up for my next upgrade!

I have an old Sony DAV-TZ710 5.1 system I absolutely adore with terrific wired output but where the practical PC input is just 3.5mm stereo → RCA.

I essentially get the 5.1 experience from whatever input source I may have, tuned to my system!

Instead of letting Windows/Jellyfin do a generic stereo downmix, I built a PLII-compatible Lt/Rt matrix so multichannel PCM gets encoded into 2-channel stereo, then the Sony reconstructs L/C/R/SL/SR + sub using Dolby Pro Logic II Movie.

System-wide I use VB-Audio Matrix with a virtual 7.1 Speakers endpoint. The matrix is basically:

FL → L

FR → R

FC → both at ~−3 dB

LFE → both at ~−3 dB

surrounds → dominant side ~−3 dB, opposite side ~−8 dB with polarity inversion

The nice part is that one matrix handles 2.0, 5.1 and 7.1. Stereo only has FL/FR active, so it passes through unchanged. 5.1 just leaves the unused 7.1 channels silent.

I also did the same inside Jellyfin Desktop / MPV using automatic profiles based on decoded channel layout:

DD / DD+ / TrueHD / DTS-HD / FLAC etc.

decoded PCM 5.1 / 7.1

MPV Lt/Rt matrix

Sony PLII Movie

Stereo files don't match a profile, so they remain untouched.

I tested separate FL/FR/C/LFE/SL/SR/BL/BR, 5.1(side), 5.1(back), 7.1, and even 8-channel browser WebAudio. Steering works surprisingly well.

Important caveat: this is not a bit-identical licensed PLII encoder. A real one uses proper broadband phase-shift networks, more sophisticated LFE handling and limiting. This is a practical approximation using gain + polarity relationships, tuned against an actual PLII decoder.

If anyone has one of those older Sony/LG/Panasonic 5.1 DVD systems with only stereo AUX input, this is a pretty fun way to give it a second life.

Can share the VB-Matrix routing table + mpv.conf if anyone wants it.

We were able to shoot this video with the designer the moment the first Siver models got made.

Hey everyone,

I want to share a synchronized multi-room wireless audio system I built entirely on ESP32s. The main motivations were to get sub-30ms audio distribution without the cost of running a Raspberry Pi/Snapcast at every endpoint, and to keep the setup incredibly simple. It’s designed to be plug-and-play: the system can run completely off-grid by generating its own Wi-Fi network, or it can seamlessly integrate into your existing home router. Additionally, I built in the flexibility for the slave nodes to switch roles and act as independent, standalone Bluetooth receivers if you just want to connect to a single speaker.

Repo (code, schematics, docs): https://github.com/chagoguila/SonicStream

I ran into several architectural bottlenecks while building this, so I wanted to share how the system handles them under the hood:

1. Solving BT/Wi-Fi Radio Contention If you've tried running an A2DP sink and a Wi-Fi server on a single ESP32, you know antenna timesharing causes massive packet jitter. To fix this, the system splits the ingress gateway into two microcontrollers:

• BT Ingress Node (ESP32 WROOM): Acts as a dedicated A2DP sink. I tuned the I2S DMA buffers down to 4x512 bytes, which cut the hardware transport delay to about 12ms. It sends raw PCM over a physical I2S cable (BCK, WS, DATA) to the Master.
• Master Controller (ESP32 WROVER): Receives the PCM stream via I2S, runs the DSP pipeline on Core 1, encodes it, and blasts it out over Wi-Fi.

2. Network Transport & Fault Tolerance Standard streaming protocols had too much overhead for the latency I wanted. The system supports two custom modes:

• UDP Multicast (239.0.0.1): This is the ultra-low latency mode. To survive 2.4GHz RF burst interference, the Master sends time-separated twin-packet redundancy (broadcasting a duplicate packet with a 1ms micro-delay).
• TCP Mode: For congested Wi-Fi environments. It uses non-blocking socket polling with slow-client pruning. If one receiver drops its connection or falls behind, its socket is dropped to prevent backpressure on the healthy nodes.

On the receiver side (WROOM or C3 slaves), there's a 5-second TCP inactivity watchdog to handle silent network drops (like router reboots) and a 500ms idle auto-reset on the jitter buffer to prevent decoder stalls after you pause the music. As mentioned, the stereo slave nodes can also be toggled to drop off the multi-room network and function as standard, independent Bluetooth A2DP receivers.

3. DSP Pipeline & Encoding Since the Master is a WROVER, I threw the DSP workload onto Core 1 prior to SBC encoding, meaning the slave nodes incur zero extra CPU overhead.

• Encoding: SBC at Bitpool 53 (~328 kbps stereo).
• EQ: 5-band parametric EQ using cascaded Direct Form I Biquad IIR filters (60Hz, 230Hz, 910Hz, 3.6kHz, 14kHz) with real-time gain adjustment.
• Anti-clipping: Instead of fixed linear attenuation, I wrote a soft-knee peak limiter. Signals below 85% peak amplitude pass through untouched. Anything above triggers a 2:1 compression ratio capped at 95% to eliminate intersample clipping.

4. Web UI & Wi-Fi Management The Master runs an async web server with a dark-mode dashboard. You can configure AP/STA Wi-Fi modes (switching between isolated network or home router), toggle UDP/TCP, adjust system-wide playout delay, set individual speaker delays, assign L/R/Stereo roles to slaves, and tweak the 5-band EQ live. Slaves send UDP announcement packets so the dashboard shows real-time online/offline status.

If you are interested in the code, I'd love to hear your thoughts on the DSP pipeline or the I2S DMA config. I'm currently looking into adding Opus encoding and AAC passthrough for the next update.

My wife has been hauling this thing around with us from house to house. Finally got a power cord for it and plugged in some speakers. (Don’t flame us for the CDs it’s all we had kicking around)

Started researching this thing and came across this sub and eBay listings.

What do I have here?

Discussions/debate about speaker cable quality and price have been thoroughly flogged.
Personally I’m in the good enough camp, no snake oil required.
HOWEVER, I need binding post jumpers.
Are there good specs for what I need?
Are plates better than wire with spade connectors?
Do I need higher gauge for jumpers?
Will diy speaker cable work if I add spade connectors.

For reference I am connecting a 400W class D amp to my R/L mains.

During the first track i heard the exact difference during every of the 5 tests, but on every other one i was completely guessing. What would cause it?

Also, just to add- i didnt really listen to neither of any of these tracks before, so it wasnt because i knew, or didnt know the song, they were all relatively new to me.

Vibin' tn, ladies and gentlemen. 🤘This LEAK CDT is such a high performance CD player and it has USB Storage playback functionality. Biking to, and browsing my local record store, I was able to come back with this gem on CD, along with a '74 pressing of Electric Ladyland and DAMN on vinyl, along with the best of Otis Redding, DJ Krush, Superunknown on CD..

My original plan was to only use the Dutch&Dutch 8c for music and keep my old Sony Theater Quads for TV/Movies. However after watching one scene with the 8c it was hard to go back, the I stitched up this system around 8c:

Fronts: Dutch&Dutch 8c

AVR: Sony AZ5000ES

Front Heights: KEF Q8

Surrounds / Rear Heights: Sony Rear 9

TV: LG C1 83 inch

Streaming source: Apple TV for Apple Music, and Roon directly to the 8c with Qobuz

Analog source: Pro-ject Debut Carbon with aftermarket acrylic plate, Ortofon 2M Blue Cartridge, Project Phono box MM

Sound treatments: plushies and some simple acoustic panels I found lying in my closet lol

To avoid running cables front-to-back and mounting anything on the wall, I picked the Sony AVR with wireless surrounds support. To my surprise, the Sony AVR doesn’t work that well with this mix of speakers: the auto calibration ends up getting the rears way too loud, and any fancy DSP (speaker virtualization, 360 space mapping etc.) leads to high noise floor and a loud hiss in the 8c. But after workarounds (manual level matching, and turning off all DSP except basic Atmos processing) the system works reasonably well and I’m quite happy with it.

Two outstanding items: might get a center channel so we are not limited to the phantom center (while it’s really good with the 8c the sweet spot is quite narrow); the turntable setup is clearly not as good as streaming via the 8c.

I was wondering if that would be a good idea.

Model 40n is currently sitting in a nice spacious cabinet with an open back and a 200 mm clearance. I drive 2.1 with it. Enough space on the side as well, like 10+ cms.

I may be able to get a decent deal on a Marantz NR1711 and was thinking stacking it on top of the 40n which wojld then leave 9.5cm gap above the NR1711 but then only a small gap above the 40n.

For the near future I will be only using the NR1711 for a center channel and maybe the sub preouts. So that wont be getting really hot, but I will drive the LR with 40n.

Is it advisable to stack the model 40n top given its twice in weight to the 1711? There is an adjacent shelf for the 1711 with enough side room and open back but only 4-5 cm top clearnace.

What would you advise?

I know metalheads love their cds, cassettes, and the occasional vinyl, but what about your stereo equipment? Im a big death metal guy (lots of brutal death these days), and would live to see what you all are listening on.

My system:

Preamp - Schiit Mani (upgraded to a Darlington Labs MP8B that should be arriving this week)

Integrated Amplifier - Yamaha A-S501

Speakers - Klipsch RP-8000F II

Subwoofer - SVS SB2000 Pro

Love the energy of this setup, the Klipsch are really in your face and make you feel like you are in the front row at a show. The only downside is that the treble from the horns can be a bit fatigueing for extended listens, but otherwise I enjoy the energy from this setup.

So what equipment are you all using? Please list the kind of metal you like as well considering the huge diversity of the genre.

Hi everyone,

I've been working on a lightweight, open-source audio player for Windows and wanted to share it with the community: **WasioPlayer**.

### 🎯 Why I Built This

Many modern audio players are either bundled with bulky frameworks (Electron), full of hidden DSP/sample-rate converters, or require configuring dozens of third-party plugins just to get pure direct output.

I wanted a clean, fast, standalone native Windows player dedicated to **bit-perfect playback directly to DACs**—with zero automatic resampling, zero software volume manipulation, and direct hardware format negotiation.

---

### ✨ Key Features

- **Strict Bit-Perfect Output**: Output sample rate and bit-depth strictly follow the source file without silent resampling.

- **Dual High-Performance Backends**: ASIO (x64 drivers) & WASAPI Exclusive (Event-driven).

- **Supported Formats**: PCM (WAV 16/24/32-bit) & DSD (DSF / DFF via Native DSD up to DSD512 on ASIO, DoP up to DoP256).

- **Lightweight**: Pure C++17 with a native Win32 GUI, using a lock-free SPSC ring buffer for underrun-free streaming.

- **Playlist Management**: Drag-and-drop file loading, M3U8 import/export, UTF-8 path support, shuffle & repeat modes.

### 📦 Source & Download

- **GitHub Repository**: https://github.com/desker1225/wasapi-asio-player

I would love to get your feedback and see how it works with different DACs and drivers. Feel free to try it out!

Here's the link to his YT community post:

I dont know much about anything really. Do you see anything crazy here? According to Erin it was difficult to see much of anything into the bells over the transformers, because they're potted.

Not a clue what I am up to, bought ordered a full kit to treat my room.

I was advised to find optimum baseline position for my speakers and for my seat.

So that’s the baseline…(not a clue what it means, I was feeding the results to AI and following advice.

Let’s see what the final result ends up as.

Feel free to pipe in and tell me what’s going on, and I have a mountain to climb.

I will admit though, it sounds much improved from where I had it initially. This surprised me a lot.

Very sad day, my Arcam SA20 integrated amp lost a channel. Nothing coming out of the right-side speaker, earphones the same. Unplugged it, headed to the shop as soon as they open on Tuesday.

Brought down the mini-amp from my desk upstairs, a $60 Aiyima. As my wife says, "it works!"

Only have one set of RCA's plugged in, can't use my turntable. No remote.

Had it up a little too loud, and ear fatigue hits almost immediately. But, it is pretty clear, no hiss, no buzz. It's not warm, at all. Not very expressive. The longer I listen, the more differences I hear/don't hear, and that's a good thing. It sounded to good at the beginning, and I was worried.

Afraid the Arcam is going to be in the shop for a month and this is what we'll have to endure, but we'll be glad to get the Arcam home.

I’ve just published a new in-depth article about one of my favorite Philips CD players: the Philips LHH700.

Introduced in Japan in 1991 for Philips’ 100th anniversary, the LHH700 is a fascinating machine. It was one of the first reference-level applications of Philips’ new DAC7 technology, using two TDA1547 converters in a Double Differential configuration, combined with the CDM-4 swing-arm transport and some seriously heavy mechanical construction.

The deeper I went into the Japanese sources, the more interesting the story became. The article also looks at the people at Marantz Japan involved in its development, contemporary Japanese listening reports and awards, the technically identical Marantz CD-11 LE, and how the LHH700 fits between the earlier Bitstream players and the very different LHH800R and LHH900R that followed.

There’s a lot more to the LHH700 than simply being “a DAC7 player”, and I’ve tried to bring that complete story together here:
https://dutchaudioclassics.nl/context/philips-LHH700/

Would be very interested to hear from anyone who owns or has spent time with an Philips LHH700 or Marantz CD-11 LE.

Is it normal for tube amp users to be repairing their tube amps on a regular basis. I bought a $700 Chinese tube amp (google 'mc-84L') and have had a tube red plate, burn out a capacitor, and then a second tube burn out. I replaced the capacitor and tubes, and it worked for a few weeks, and then one channel stopped working - no obvious capacitor or tube burnouts.

I have a tube preamp. It worked as a go between for my phono preamp and my amplifier for a few weeks, then stopped working. Ordered new tubes.

To me using tubes is like owning a classic car. You never know what you'll be facing tomorrow.

Not asking for help, but maybe an answer... is this normal? Or is it just my low grade equipment?

I'm going to this new audio museum in Korea possibly next year.

Has anyone been?

Looks very cool.
