you very much should care...and I'm not here to break anyone's business.
see it as those ppl who buy regular cars, and put "momo" racing car wheels and modify the car completely to be a lot more nervous on the road. many ppl like those cars w/o all those modifications, it's not a crime!
someone on the forum said that talking about sound was like dancing about architecture...and there' a manufacturer that says that listening to cheapo opamps is like listening to an orchestra through a key hole.
what is coloring the sound the most is your V100 is -more than likely- the cheapo 5532's. do you find it normal that the sound of a $600 amp goes through $0.3 opamps? seriously?
You don't seem to have much experience in rolling opamps, and you can rest assured that you ARE (most exclusively) listening to the 5532's when you turn on your V100.
here's an attempt from Ray Samuels(another amp manufacturer), trying to explain what the LT1028 does to your sound(it's one of my three favorite opamps): REVIEW: Ray Samuels Emmeline HR-2 - SGHeadphones
that's what LT1028ACN8 does. really.
it's expensive, and I think it's still a hell of a bargain(and should have been priced 4X higher to be taken more seriously )...I'm sure the V100 would be eye popping w/ a bunch of these. try it, become a believer...don't be afraid...well, actually, be very afraid because the SQ will be a night and day and you won't quite be able to turn off your amp anymore
PS: about your DAC question, same answer: Heres some test results for the new ESI Juli@ card.  - RightMark Forums
the OPA2134 in your Matrix DAC are ruining the SQ completely
I am afraid, according to the description what these amps that you suggest do like
As Mr. Samuels once remarked, the LT1028 is like putting sugar all over your sound
they would not help a bit in the quest of reproducing the sound as close as recorded.
I do not wan't sugar all over my Mozart, Hydn, Stravinsky etc nor cream or dope. I do not fry eggs when I listen to music - so I strongly believe a tube amp is superfluous (the second one you suggest) .
And also I do not need military grade components & wire in my amp.
The temperature in my room is average 18-20 dgs cent. So no freezing and towing cicles that can screw the components and make them unstable.
Can you suggest an amp that can help HD speak the truth ?
