Saw these on AliExpress for $1099 ready to be shipped. Not sure if they are real so I wouldn't risk it. I think of the A83 as a competitor with the ever so overhyped SE846. It will be interesting to see how the newest model in the Fidue line will be received. I plan on making it my first $1000+ IEM.

There is a forum here on it, I'll find the link for you. It's a more refined treble than im70 with equal bass qaunity yet higher bass qaulity than the IM50. It's great for those looking for a upgrade from both.

Try the audio Technica e40 or Ckr9

That sucks. I would tell you to go to eBay but, you can't trust the quality.

I got mine for $180.

Try the Audio Technica MSR7's best look to sound qaulity ratio (which is what I think your preferences are) headphone around. You won't be disappointed.

MSR7-it was built for music Differences from m50: -More treble and the mids feel closer (like you are microphone being sung into) -Tighter bass -greater clarity and accuracy Cons: Source dependent. Will reveal bad recordings due to the increased in clarity.

I hope they fixed the issue with the distant mids. If they did it's worth maybe $250-$350 not $500-$600. The biggest issue is the fit and cable. There's a market for this product internationally not sure why it's Japan only.

I would reccomend the Ckr9. They are basically the MSR7 on ears if you're familiar with those headphones. I would not get the LTD 90% are fake you can only find real ones in Japan. Other than that: Triplefi 10 -I know a guy who can give it to you cheap brand new with a replaced cable FidueA83...
