Thanks...

I voted 75% desktop, 25% portable.     And by the way - I wrote here a few words about the iFi iPhono:   http://stereoikolorowo.blogspot.com/2014/01/ifi-iphono-przedwzmacniacz-gramofonowy.html   Enjoy!

Matrix mini-i is wonderful!! I use it together with Accuphase E-213 and Musical Fidelity A1 CD-Pro. The sound is fast and crystal clear.

Shuguang Treasure KT88-Z are amazing! I listen to them in comparison to the Russian tubes and the advantage is on the side of the Chinese people!

Project86, Thank you for the excellent and comprehensive review. There is something to read!   I have Matrix mini-i and Matrix M-Stage, and with great amazement and curiosity, I look at what the Chinese company will produce more good.

Question. Do you turn off the power of Matrix M-Stage during non-use? It is terribly hot. I am afraid that something inside it will not spoil.

Please be informed that the Matrix M-Stage famously works with Sennheiser HD598 headphones. The sound is close, strong and very uniform. Basses are more than wonderful!

OK. I also bought a Matrix M-Stage. I will listen to how it will be played with the Musical Fidelity CD-PRO A1 and differs sonically from amp's - Matrix mini-i and Musical Fidelity X-Can v.3

Nice sale of Matrix Cube 24/192 ASRC DAC :)

I already have a Matrix mini-i. It is really nice: sweet, spacious and detailed sound. I like it very much. Compared to the Musical Fidelity X-DAC - Matrix is slightly less warm, but more detailed and has a broader sound.

Can I ask for an opinion on the latest version Matrix M-Stage? Someone has already listened to? Alternatively, please link to the description. Thank you.  ...

  Scrivs, Pricklely Peete,   Thank you for the interesting description of Dr. DAC DX. I interested in the topic because I plan to soon buy the DAC in the price of less than 300 USD :)         

  Does anybody know what happens to the Matrix Cube DAC? There was a short information, which then disappeared!

Only HD650! And forever! :-)
