Had a pleasure trading with TWerk: he was friendly and knowledgeable, quick to respond, and shipped the amp in two boxes to make sure it would be comfy. Highly recommended.

My fav is the iFi iDSD Black Label, but for the sake of this survey I'd pick the iFi Micro iTube2

It would be my pleasure! Are you making it to LA for CanJam? Or alternatively - any plans to be in NYC any time soon?!

Thank you - you're welcome.

I've compared the MH40 to the Mad Dog and AudioQuest NightHawk, using the Questyle QP1R while listening to the fascinating and stunning new recording of enfant terrible conductor Teodor Currentzis to Mozart's opera "Così fan tutte", whose range of masterpiece music run from orchestral music to...

What I refer to is that the OS is pretty reliable - very little cases of downtime. The QP1R is an outdated OS, which on its own, is something I find negative, and in addition I had hard time updating the music library.

Based on the last 4 days, it seems so - I didn't encounter any gapless issues.   In general, the system seems to have little issues. The one aspect of the DAP that I cannot discuss at length is the ability to use it for streaming, as I use it 99% of the time for files dowlaoded to the internal...

Hey Brian, I can confirm that version 2.5.6 does indeed include gapless playback

Thanks @bcarr112281! I just checked, and I have the latest firmware, but had issues with gapless playback. Not sure why, but now I will certainly explore this further.

Hey Rob @robfol,   Thanks for your response. Although the M2 can drive... I do feel that with some of my cans - like the HE400i and Alpha Dog - they reach the maximum volume without actually optimizing the punch that I'm looking for. And I feel this would be even more challenging with the...

Hey @AR-Voice,   Was wondering from your experience which portable amp work best with the AR-M2?   Thanks!

Hey Brian,   It does sound like we have similar taste in music, and I feel that the AR-M2 would make you a happy man.   Functionally, it is far better than the QP1R and all the other players I used, incl. the AK.  The android platform is seamlessly integrated, allowing to use digital...

Here are my subjective impressions from a concentrated listening session to the AudioQuest NightHawk, followed by a comparative listening session with the similar priced MrSpeakers Alpha Dog.   The source I used was the Questyle QP1R, and the music used was Beethoven's String Quartets played...
