Matrix Mini i DAC

It is really convienient and user freindly designed.
Pairing with Little dot MKVII+, the sound is amazing for classical music listening.
It drives reasonably DT990-600 ohm.
 
I have several audio sources, all of which are able to be connected to this many interfaces without swapping the connect each time.
The LED indicate is pleasing and shows how it is connected and operated.
 
Strong and heat dissipating aluminium case is very good for a long listening.

 
I bought this used with a reported 500 hours on it, so I assume it is broken in.
I really like the Mini-i, the soundstage is HUGE! (width & depth)
It also has a lot of texture and airiness to the mids, instrument sounds seem expanded.
Along with the soundstage, the instrumental separation is very good too,
(most of the time) Things only seem to get "muddy" with a huge wall of sound.
That is, many instruments playing at the same time in a crescendo.
But that is also typical of many dacs, amps and phones.
My only real complaint is that some of the highs that are not center stage
are rolled off, or seem to be muted somewhat and put in the background.
I am comparing this to my other DAC which has great treble characteristics.
(almost sibilant) 
So now I see what everyone is referring to regarding the mini-i's sound sig
being almost tube-like.
 
I have not tried the balanced outputs yet, so my perceptions may change.
(I am hoping for the better)
Right now I'm using USB, and mostly lo-res recordings, so that limits things as well.
I know that I will be having a great time exploring the limits of this machine.

Had it in my rig for a few months, might have been unsuccessful in breaking it in properly but after much consideration my Kingrex UD-01 SE with the PSU unit stayed and the Matrix went away. I experimented with using the optical toslink instead of USB but the Kingrex still stood strong, which I didn't expect. Still, a good buy at the 240 something (not quite sure exactly what I paid anymore..).
