So I've just popped in the D7000s into the Concerto and I must say that this amp continues to impress me on Day 3 (Day 1 --> T1, Day 2 --> HD800). So far, I'm 3 for 3. Likely the best SS amp I've heard the D7000s on and I think I prefer it to my Mapletree tube amp.
The bass is just better controlled and deeper and they are less "U" shaped than on the Micro Amp. The mids don't seem as distant and the treble has just the right amount of sparkle. The other amazing thing is the sound stage for closed headphones is very impressive. They seemed closed in with the Micro Amp, but not with the Concerto (Low Gain).
Very nice and I'm quite happy with this combination....actually my favourite to date for the D7000s.
Jan Meier has created one amazing amp for under $1K. It can successfully power the T1s (600 ohms), HD800s (300 ohms), and D7000s (25 ohms) to incredible heights.
heh, glad to read Peter!
I was pretty confident the amp was going to continue to impress you with the D7000.
It truly is a killer amp for the price.
My favorite part of the sound is how well defined the soundstage and imaging become. Very 3D and precise with all the headphones I have tried. Couple that with the crazy low noise floor, and almost perfect neutrality, and we definitely have a winner.
They also drive the LCD-2 very well, so truly an all rounder than people can count on for excellent sound, regardless of the design of the headphone.
