Why do you keep starting duplicate threads?

@thecarpathian, it is part of the young audiophile’s upgrade path...a sad, impatient, confused one, especially when on a budget ( but I speak for many of us ). I responded to his other, duplicate thread. A complete rebuild would be more than his budget, but is an amazing thing ( new chassis, new connectors, new attenuators for volume and tone, and a few more goodies ( all this from AliExpress )

No. Not worth the change. Listen to ghdprentice. You're not going to find anything better for $300. NAD 3020 is a classic. You'd have to spend a lot more to out perform it.

What are your sources and speakers? Keep the 3020 and focus on those if you really want to hear a difference.

If you can swing $600, get a Denon PMA-2000. The original. It has a light gold color anodizing. A great amp in my opinion. This amp will pretty much drive any speaker, and won't need a rebuild.
