I just sold my late 80’s era ARC D70Mk2. Replaced it with a pair of new Mono blocks that use the new KT150 tubes. The ARC was an awesome amp...even by today’s standards...back in the day...NOTHING could have touched it! However, the new amps are so much more resolving and a lot more capable at both frequency extremes. The new tubes may be accounting for this, but the fact is that the ARC was still highly competeive in my system after all these years...VERY impressive.
Have we seen an increase in SQ from the latest amps compared to yesteryear...I vote yes, but not to the extent that one would expect over this period of time.
