V100 is a great amp , do not know which opamp No. or what is inside - have not opened the box yet; what ever they did HD 800 likes it and so much more I like what I am hearing. There might be a better amp for HD 800 outthere - so far could not find one - any ideas ?
V100 is not cheap but worth every cent if you want to come a huge step closer to the real thing (live classical acoustic concerts, jazz or whatever music).
Some tube and hybrids costing few times more than V100 kind a suffocate HD800, somewhat colouring the sound in a worst possible way i.e. you can not hear what is HD800 in reality capable of : transparent, sound stage, instrument separation, speed etc.
I am not mentioning those amps - maybe other people like what they do, I am surely not. To me it looks like no "christmas tree amp" can properly drive HD800 ?
