I’m happy to say that I use a 3020i and a 3225pe in a bi-amp setup and love them. The 3225pe drives the woofers in my Energy Connoisseur speakers and the 3220i drives the mid/high. They are basically the same architectural design, but the pe has an additional set of higher voltage power supply sections and a few other tweaks. The NAD service manual is even the same, covering both models.
Whats your take on a NAD 3020, I truly believe it defined stereo and still does!
No matter what I have on the audio front, this old baby just flows through my home.The tone is pure ...she is my reference and always be such.Am i the only one who loves the old girls?Rotel, Marantz, HK, Arcam, Cambridge and retro including class A all have a unique sound.
