Frankly, i’ve built many amazingly good systems around a lowly NAD 3020 A Integrated and eventually adding a more robust power amp….. BUT by putting the bigger $ into the transducers ; cartridge and speakers.
One such combo: Denon DP-47F > Grado Sonata > NAD 3020A > Vandersteen 1’s
BUT i understand the itch to try and learn by doing….
Lets coordinate for loan of a tube Belles preamp, so you can evaluate the change, scratch the itch and not be out any $…..
