Fantastic! Glad I could help. Let me know your impressions once you get it. I love that X Bass switch since I'm a bit of a basshead. The only drawback to the amp that I've found is a lack of a power switch. To get around that I use it with a remote controlled power plug that I bought on eBay for like $10 to turn it on and off.
I've had enough time to evaluate the M1060C's (open modded) with the iCan SE and it is a pairing I really like: smooth, detailed yet very relaxing and non-fatiguing.
After converting these cans to open and running them via this hybrid tube amp they perform very well and punch above their weight - providing you give them enough juice.
I first tried this set up: Schiit Modi Multi > iFI iCan SE (Listening mostly to FLAC files through J River)
I liked it. Very clean sound. Bass extended low (nothing missing). Mids were pleasant (Do not find mids shouty or hear any ringing). Vocals pushed slightly forward but i like that.
Then, out of curiosity, I incorporated my Sony STR-DB790 again as a pre-amp feeding the iCan SE.
Not as black a background as before but... Goddam! the overall result was a lot better.
I was happy with how it was before but now, with the Sony's extra power, combined with the smooth / warm sound signature of the iFI iCan, these M1060C Opens suddenly came alive. I've test driven some LCD2 Classics and ZMF Atticus recently and really liked their impact and how they make you feel the music in a tactile way. The M1060C's are now getting closer to that experience (but a little less thickness and a bit more brightness).
Instrument separation, placement, imaging, detail and micro-detail are all improved. The music has become more holographic. Sometimes the sounds are happening around me and I am sitting in the centre of a performance.
What also increases the realism and enjoyment is that my open M1060C's can now dish out bass with authority. The detail and texture is outstanding. If i switch the iCan X-Bass on (and eq bass up a touch on the Sony) it is pure bass bliss. Clean, fast, detailed, extends way down low and makes my skin vibrate. Its not bloated and doesn't bleed into other frequencies. (I don't like overly bassy closed cans because of weird resonances that make my ears ring). This crap was clean though, completely controlled with no distortions.
The headphones have suddenly come to life and in turn brought the music to life. It allowed me to listen to my music collection in a completely new light. I heard details i didn't realise were there even though i'd heard those songs many times before.
I love the sound signature of the Modi Multi & iFI iCan combo. It just needed a touch more power to make the M1060C Opens shine.
I will replace the Sony in the future with a better, cleaner solution. But keeping me happy for now...
