Thanks again for the responses.
Ok, so my Onkyo built in 1989, though perhaps their best machine at the time, will sound similar to a decent machine built today? Or going with a second hand dac is a much better upgrade? Then, does anyone have experience as to how the onkyo fares as a transport?
To update on my Dyna, I swapped the tubes in the line section for the ones in the phono stage, and they were good. At the same time cleaned my (I'm embarrassed to say rather tarnished) copper power cord plug and expanded it for a tighter fit, and the results were definitely noticeable and positive. Could it be that the signal from the cd player is more vulnerable to uneven power due to the greater frequency range? I'm starting to think an upgrade from Curcio Audio on the preamp may be a step in the right direction.
As for the amp, the friend who gave me the Dyna Pas also gave me a couple of non-working Dynaco st-70s and I was thinking at some point of repairing one of those, and possibly modifying, perhaps with Curcio's drop in assemblies.
Mahalo,
