One data point. Not a HK 3270 and do not do vinyl. Do use a similar, slightly newer, HK 3485 (120W/Ch) as the focal point of a 2-channel CD/USB FLAC/BT 2.2 bookshelf speaker system in a small room.
It performs beautifully. Bought the HK used in ~2015 and have no regrets. It has a strong, smooth amp section and the functionality I need.
There is no bass management except for pre-amp out / main amp in.
To integrate a sub, I use a Sub that has 80Hz HPF RCA outputs. Then reconnect back into the HK's main amp in inputs to limit what the books are asked to reproduce.
Cheers,
