20 Year Old Amplifiers compared to 2017

Class D and digital amps are relatively new, thus do not have vintage counterparts.

I do say that the early Pioneer Elite Class D amps that were used in their upper end A/V receivers were not bad. I used one from 2003 for 2 channel music for a few years and was surprised how dood it sounded to stand alone class A amps that I tried. 

Whenever one of my class A mono blocks needs service, I pull out a 20-year old Hafler P3000 studio amp from the garage and replace it for a while. Always have the same two reactions:
1. Surprised at how good the Hafler sounds
2. still, can't wait to get the mono block back
Have recently tried a Nord class D amp and did not find it in the same league as class A amplifiers.

+1 on that, listened to many "good" ones now that owners say are good, but they still don't cut the mustard.

@aardbear, CJ makes great stuff, always has.  Not sure why more on this site don't use it.  ARC gets way more love, CJ used to be more competitive but has not kept up with the volume of innovation.

You have very nice gear!
