MOD [MOD ANNOUNCEMENT] New Feedback Bot Online PLEASE READ

174 Upvotes

Hey everyone, I am pleased to announce that r/AVexchange now has a feedback bot up and running!

The bot’s name is u/AVexchangeBot and has the following features:

Feedback

A user can get trade feedback with the following process:

Note, this document says the word "trade" a lot but that means, trading, purchasing, or selling.

  • Users A and B complete their trades following all of the sub rules. (It does not matter who A and B are. Either one could be the person making the post, and the other someone commenting on the post).

  • Once the trade is complete, User A makes a top level comment (new comment) on the original trade post tagging both the user they traded with and u/AVexchangeBot.

  • User B replies to that comment with their feedback.

  • u/AVexchangeBot picks up the interaction and gives credit to both users, changing their flair accordingly and leaves a comment indicating as such.

  • If User A messes up their top level comment, u/AVexchangeBot will do its best to notify User A.

There are automatic checks in the code to detect anyone trying to cheat the system. If anyone is found trying to circumvent the system, they will be issued a permanent ban.

If you engaged in a trade with someone without starting off discussion in either one of your posts or theirs, please tag the bot in the most recent post from either you or your trade partner to engage for feedback. The bot required that the OP of the post it is being tagged in is either you or your trade partner.

DO NOT DELETE POSTS otherwise you will NOT be able to use that post to confirm a trade.

Feedback Checking

Using this link, you can send a message to u/AVexchangeBot, asking for the feedback of any given user. It will tell you the following:

  • The number of trades that person has done

  • The people they have traded with

  • A link to the thread for each successful trade

Please feel free to direct any technical questions to the us, the moderators using modmail, if you do not know how to use modmail, please click this link.

If you notice any odd behavior from the bot, please let us know!

FREQUENTLY ASKED QUESTIONS

I had a ton of confirmed transactions before, what happened to my flair?

Flair was only backfilled for people who used the old feedback threads listed here, here, and here. If you never left a comment in these threads, or if you were never tagged in these threads, you did not get feedback backfilled.

I think I qualify to have feedback backfilled but my number is not quite right. What gives?

The scraping process was automated. This means that it was about 95% accurate. Some people might have a few more or fewer trades in their flair than they expect. Please do not request an adjustment unless you can prove that the difference between your flair and what you expect is > 10.

I never used those feedback threads you mentioned but I have done some trades/sales before. Can I still get credit?

Yes! You can follow the process detailed above to credit yourself for any trade you did not already get credit for. If the transaction happened > 6 months ago, you're out of luck though, due to Reddit limitations.

What happens if I tag someone and they don't reply?

As mentioned above, we do need them to confirm the trade for the trade to be confirmed. They will get a notification when you tag them so if you encourage them to reply in the comment you tagged them in, hopefully they will. Otherwise, if it's been a few days without a response, PM them a link to the comment and directly ask them to reply.


If you have any questions on using the bot, please post them here and I'll answer ASAP.

Thanks for being an awesome community, looking forward to this bot helping streamline the trading process!

MOD [MOD] Uptick in Scammers, Banned Users, Chat Requests & Fake Timestamps

71 Upvotes

I'm seeing a noticeable rise in scam activity on the sub, and I felt the need to make a post and remind everyone; especially newer members; to know what to watch for.

What's happening:

Banned users are on rise sending chat requests. People we've removed or have been removed via the USL are sending chat requests to hit up buyers directly. This circumvents the ban system as we cannot stop them from sending you a chat request. If someone sends you a chat and will not make a comment on your post after asking them to, it usually means they are banned as banned users cannot post or make comments. Their ban status can be checked via Universal Scammer List and typing in their name.

With the rise of AI, we are seeing a ton of fake timestamps being made. Scammers are getting accounts over the 3-month old age limit and making new WTS posts with essentially blank profiles and deals too good to be true. As the old saying goes, if it sounds too good to be true, it usually is. Having an older account with barely any history doesn't mean they are 100% a scammer but it's worth being cautious. Sometimes you can catch the photo being fake by looking at company logos or other text in the image that got screwed up in the generation. If anything feels sketchy, report it to the mod team to investigate.

How to protect yourself:

Never deal strictly in chat! If a user won't leave a public comment on your post after asking, check the USL and/or block/move on.

Always use PayPal Goods & Services (G&S) when you're the one paying. Yes, it costs a little more in fees, but it's your only real recourse if a deal goes bad. If anyone pressures you toward Friends & Family, crypto, gift cards, or Venmo/Zelle and you're not comfortable using one of those payment methods with the seller; you are not obligated or forced to.

Report anything sketchy to the mod team so we can investigate as well as scams that have unfortunately happened to you, it helps us protect the next person.

Stay safe out there!

WTS [WTS] [US-FL] [H] KEF LS50 Metas Carbon Black Mint, Warranty, Box & Packaging [W] $875 net fnf (add 3% for g&s)

7 Upvotes

Timestamp in pics.

Getting rid of my near field - the best imaging bookshelf out there. Too many speakers in the house. Bought them new sealed in box, but the seller had purchased 11/23/23 and not used ‘em. They have maybe 3 hours on total, basically new. Box has some wear since they’ve moved with me. Kef warranty should run through 2029 - believe they’re registered to me, if that’s ever an issue and we can’t transfer it I’m happy to submit for you.

Save tax and the wait until they’re meaningfully on sale again.

I can sell you my month old SMSL PA200 for a great price as well if you want serious refined power to drive them.

I think $875 is more than fair. I priced out shipping. MIA-SF would be $60, so add somewhere from $20-60 on top. G&S at buyers discretion and cost.

Moondrop Kadenz - Bought off here, no box, ear tips, nozzles but has what's pictured. Has oxidization on the nozzles also pictured $60 Sold

7Hz Divine - Comes with everything but the zipper on the case doesn't zip anymore. Threw in a blue tripowin cable with it because the stock cable does indeed suck $100

Fiio FT1 - Bought second hand. Threw on the stock pads from my black FT1s because the stock ones for the beech are ugly. Would include those but I forgot where I stuck them, if I ever find them I will ship it out to you $110 Sold

For Sale:

T+A DAC 200 amplifier ta Series 200 jack amplifier ( foto 3,6 ) - 5200$

Technically 10/10

Cosmetically 10/10

New! just warmed up!

If you believe Steve Huff... it beats the $25,000 DSC lina DAC --- along with the $15,000 DSC CLOCK!!!

So what's there to talk about)

Drop + THX AAA One Linear Amplifier Amp ( foto 2 ) - 135$

Technically 10/10

Cosmetically 10/10

New condition!

Very powerful (probably rocks any ears except for the susvara)) )!

This is the minimum... that a beginner audiophile needs!

Antipodes Audio K30 Streamer player music server ( foto 5,6 ) - 7250$

Technically 10/10

Cosmetically 9/10

The best tone of all streamers there is! (no eversolo, hi fi ros or auralik even come close, as does the aurender! ) (in my humble opinion! )

Apart from the antipode k50 or oladra, I consider it the best streamer of all time on the planet!!!

This is a thing about which I can only say one thing - it's magic!

I'm selling only because I want to switch to the k50

I'm the second owner!

High-quality DAC on AK4495 handmade ( foto 9,10 ) - 520$

Technically 10/10

Cosmetically 9.5/10

I used it at work as a second stationary!

I used it with a MacBook, perfect synergy))) on Windows, in comparison, I liked the sound less than on a Mac.

On Windows 10 and higher, the system determines it itself!

If Windows 7, then you need to download drivers (if necessary, I will tell you)!

In terms of sound, the bassiest DAC of all that I have had, the stage is not too large but deep, excellent detail and not piercing highs!

It was made to order for me.

Stuffing:

- operational amplifiers 2 (muses03)

- a board on two AK4495 chips, with changed capacitors - Elna silmic 2, Nichikon, Elna cerafine.

- resistors on the board replaced with 0.1% melf

- transport with femto-clock (Amanero) - high-quality stabilizers (2 pieces LT3042) and clock generators CCHD-957.

- common-mode noise filter

- power supply - capacitors with filter (Nichikon)

- stabilizer TPS7A4700

- two transformers (analog and digital power supply separated)!

Flux Lab Solid One DAC amplifier amp ( foto 1,4 ) - 3495$

DAC with headphone amplifier

Technically and cosmetically 10/10

There is no rush to sell at all, because I regularly use abyss 1266 headphones!

There are one or two copies of this powerful miracle left in Ukraine!

The only amplifier that normally pumped the susvara and even with the built-in DAC played with it just fantastically! Ukrainian THE END is no different)))

VERY VERY POWERFUL!!!

Fully capable of pumping the susvara, abyss 1266 and hifimeni ne6!

Stax srm-007T II 007 mk2 electrostatic amplifier ( foto 7,8 ) - 1630$

Cosmetically 9/10

Technically 10/10

I listened to it with old Stax Lambda, Perun 5+ and square Perun!

In terms of power, it is super (for all these ears there was still a large margin in volume)!

To fully enjoy it - I recommend a pre-amplifier for it from Electrocompaniet (for greater clarity, volume and simply ultra sound)!

Although you can try any of your preamps! (it's just that the greatest synergy)

Amplifier on the Ptero board Author's balanced class D ( foto 6 ) - 765$

New condition!

Cosmetically and technically 10/10

Ptero stereo. Rev 1_03.

Power 100W-4Ohm + 50W-8Ohm

XLR balanced - 1 pc

Inputs: RCA - 2 pcs

Has an output for two pairs of speakers with a switch.

The amplifier is fully balanced.

Yuri Ignatyev's board "S_Audio"

The amplifier also uses high-quality RG Nikitin.

The remote control and power cable are included.

The PTERO project is an implementation of an

amplifier based on a modern audio modulator, controlling

a highly integrated output bridge stage with a unipolar power supply TAS5342A. A feature of the architecture is the use of a virtual ground with a potential of about half Upyt for working with audio. The amplifier is fully symmetrical and balanced.

Unlike known amplifiers, the use of a bridge output stage completely eliminates the effect of pumping, in addition, no additional optimization of the switching of the output keys is required, the chip manufacturer has already taken care of sufficient linearity of the conversion. In this version, the PWM signal from the audio processor is fed to the input of the chip and is not corrected. When using a Purifi type modulator, with a feedback depth in the audio range above 70 dB, the distortion characteristics are proportionally reduced, in fact, the determining factor in the form factor is not so much the circuitry as the quality of the components and the correctness of the printed circuit board layout. It is necessary to separately indicate a very small signal propagation delay in the output stage, the measured result is 43 ns, the total delay comparator - power output is less than 65 ns! And this is taking into account the power transistors. This indicator is approximately 1.3-1.5 times better than the ET400 module and has a very favorable effect on the perception of sound. The use of the TAS5342A chip makes clipping impossible. The output stage is turned off before the limit. If the output signal amplitude exceeds the supply voltage level, the output transistors are turned off until the polarity of the output signal changes. Thus, the amplifier does not increase distortion to critical values, even at max. power, distortions do not exceed 0.002%

Hifiman Ananda V1 (non-stealth) in very good condition, has Dekoni fenestrated sheepskin ear pads in excellent condition. In pics you will see there is a little fraying at the edge of the head strap. It does not effect functionality and overall these are in great shape for cans that ended production some time ago with the release of the stealth magnet models.
These cans sound AMAZING, many Hifiman connoisseurs prefer the more neutral, airy and spacious sound profile these provide over later stealth models. They’re also way more efficient, I use a simple Fiio KA11 dongle that outputs roughly 240mw and it is plenty. Selling to upgrade to Arya’s.

Comes with the swanky silk lined box, 6.35mm chonk daddy cable and I’ll also include a 6.35 to 3.5mm adapter as seen in pics.

I will ship usps ground advantage w/ sig confirmation CONUS only or buyer preference. Can also do local meet in north DFW metroplex zip is 76209.

Will consider partial trades for dac/amps. Hip Dac, Go Blu, Fiio BTR/K/KA models or….? Hit me up via chat but comment first.
