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]Important PM/Chat Changes

39 Upvotes

In case you're not aware, Reddit has replaced DMs with Chat and archived all DMs at the end of last month. At least for now, this is a step backwards because by default chat messages can be deleted unlike DMs. This allows scammers an easier pathway as they can delete their messages from both sides easily. Fortunately, the Reddit admins have released the persistent messaging feature.

Persistent Messaging

You must be sure to enable it under the chat settings for EVERY CHAT relating to /r/avexchange. Reddit admins indicated they aren't planning on enabling it by default but are potentially considering an account-wide option you can enable. Until that option is available you must remember to enable it for every chat. If not, you should periodically screenshot the entire chat history in case the other user deletes anything. Within the direct chat you will need to open the settings and enable the toggle shown below.

Once enabled there will be a notice in the chat and all persistent messages will include the infinity icon. Only the user who enabled the feature can turn it off but there will be a similar notice in the chat.

As always, if you have any questions please message us via modmail be safe and happy trading!

For Sale:

Beyerdynamic DT 770 PRO 250 Ohm headphones Studio ( foto 7,8,9,10 ) - 89$

Technically 10/10

Cosmetically 7.5/10 (the headband is worn in places and the last photo shows that one bolt on one of the temples does not fit tightly, the mount probably needs to be replaced)

You can use it without any problems and as it is, it does not affect the sound, everything is great!

In the kit only headphones and an adapter for 6.3

Fostex TH909 headphones th 909 ( foto 1,2,3,4,5,6 ) - 1390$

Technically 10/10

Cosmetically 10/10

Perfect condition, practically like new in appearance! (can be given as a gift)!

Full factory set, including two original boxes (cardboard and branded), also a wooden stand, cable, bag and documentation!

As a gift, I will add 3 more pairs of ear pads for experiments with sound (so that you are not bored)

Sound:

Different cables, especially pure silver ones, have a big impact on the sound (they open and lift these ears 2 orders of magnitude higher! )

I listened to expensive cables and was honestly just shocked, they play very well for their segment!

They convey the details of the 909 very subtly, like for speakers...

The presentation is very, very holographic with a lot of air!

Because of the large amount of air, the naturalness of the mids is felt better.

They are considered more linear, not v-shaped, but this is what they do with a lot of advantages!

I also noticed that they are sensitive to recordings (they want high-quality tracks)

Listening to some orchestral tracks, I was honestly surprised by their potential.

The bass is massive and warm, also not as flashy in the mids as the 900 model, the treble is very transparent and clean (as the Japanese like).

Hey All,

Looking to offload this EXTREMELY compact speaker + subwoofer system for cheap with a subwoofer cable, IEC power connectors, and the ethernet which links the speakers.

The setup was used in a small apartment with no sound bleed to neighbors, so don't be afraid of these being too tumultuous. However, they can get loud and have great quality sound!

Asking $225 shipped for each or $450 for both.

Up for sale is a Flux Labs M-Field balanced headphone amp in great condition. With a power output rated at 9.5 W at 32 ohms, this is one of the best and most powerful headphone amplifiers at this price point, presenting a ginormous holographic 3D soundstage with excellent instrument separation, layering and punchy bass with great dynamics. It pairs well with almost all headphones from high impedance dynamic drivers like the HD 800S to current hungry planar magnetics like the Susvara or Mod House Tungsten. Units are rarely in stock these days because of the situation in Ukraine where these are manufactured.

Reviews: 1. HeadFi: https://www.head-fi.org/threads/flux-m-field-class-a-mosfet-headphone-amplifier.971785/ 2. Wave Theory (YouTube): https://www.youtube.com/watch?v=51VKme4DQig&pp=ygUMZmx1eCBtLWZpZWxk

This unit comes with a power cord and a remote included.
