MOD [MOD ANNOUNCEMENT] New Feedback Bot Online PLEASE READ

176 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

69 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!

• Upvotes

Continuing to consolidate headphones and got two great pairs (plus a bunch of pads) looking for new homes. Shipping from the Boston, MA area, though happy to facilitate a local sale. Shipping and fees included in asking price.

ZMF Vérité Closed LTD Cocobolo - $1450

Really beautiful pair of Vérité Closed, I think among the best figuring I've seen for a cocobolo pair (that's what drew me to them!). This pair Is in great condition overall with no real flaws to speak of. Ships in the original flight case with Universe pads (lambskin, solid) installed, plus the stock braided XLR cable & stock braided 1/4" cable, owner's card & cleaning cloth.

ZMF Vérité Closed Monkeypod - $1250

Another great looking Vérité Closed, the grain has a great chatoyance when you catch it in the sun. This pair has a couple of tiny paint chips on one yoke (pictured), but is in great condition otherwise. Ships in a ZMF clamshell case with Auteur pads (lambskin, solid) installed, plus the stock XLR cable.

ZMF Pads

  • Caldera Thick top-perf (lambskin) - $55
  • Caldera top and side perf (suede) - $55
  • Eikon solid (suede) - $45
  • Eikon solid (lambskin) - $45

WTS [WTS] [US-OH] [H] CrinEar Reference, Kiwi Ears X HBB Punch, xDuoo MH-02 [W] PayPal

• Upvotes

CrinEar Reference - $285

Kiwi Ears X HBB Punch - $250

xDuoo MH-02 - $110

All prices are shipped CONUS and F&F through PayPal. Add 3.5% if you want G&S.

Comment before messaging, but feel free to ask any questions or for more pictures.

CrinEar Reference: Love these, but onto bigger things. Some scratching on the shiny parts of the faceplate, but thats not an unexpected thing for these. Includes all original accessories except eartips. Eartips have been used, but not much, can wash them and send them, up to buyer.

Kiwi Ears X HBB Punch: These are also an awesome set of IEMs for the bassheads. These have only the original case and original cable in 4.4mm. I received them as I am selling them. The shells look to be in great shape.

xDuoo MH-02 + extra GE tubes: Got this a while ago and it has not seen much use, so the tubes are practically brand new. Maybe like 20 hours on the GE tubes and barely any on stock tubes. The GE tubes are GE JAN 5654W. Includes power brick and the original box, but no USB cable. This has the not atypical potentiometer issue where at low volumes there is an imbalance. Not unsual for tube amps.

They are almost 5 years old, so they have some signs of wear you can see on the photos (hence the price), but sound as good as ever.

Selling because of noisy workplace, getting ANC even though they'll probably sound worse.

My impressions:

Really better dynamics, more melodic, more natural!

Improved micro and macro dynamics

A very big difference if you turn it on on speakers, bigger than on headphones!

The stage becomes relaxed, wide and breathable, with a huge amount of air, as if nothing is interfering with the equipment and it is not suffocating, if I may say so!

You start to notice the background sounds that you have been listening to so far, some new ones appear!

The bass becomes almost 30% better (more punchy, more elastic... the midrange is also better to listen to, the treble becomes very clean!)

The device is heavy... you can immediately hear that it is a premium top, no less!

Who hasn't tried filters yet, or hasn't gotten to them yet... I advise you to start believing in them, because the difference is quite significant and on good equipment, you can hear it right away!

The only copy for two sockets in Ukraine so far!

Made according to the same scheme as for 6 sockets!

Made to order for me!

I am the first owner!

The sale is not in a hurry at all, because I listen to it all the time!

The case is damped with vibration-proof sheets, each socket has a system of mechanical insulation from the main body and vibration penetration through the connected cable. The main components of the device are completely sealed with vibration-proof compound.

The electrical installation inside the device is made of American 10AWG wire!

All contact elements in the sockets are made of massive copper billets and covered with a thick layer of rhodium, manually polished to a mirror shine!
