I had the same experience when I demoed Hegel 390 with Harbeth 30.1. It took in a dark tone and was over damped, at least for my taste. The best pairing was with Audio Hungary Qualiton a50i. It added that extra bit of airiness at the top that some Harbeth models lack.
Integrated Amp Pairing for Harbeth 30.2
I am asking you to suggest compatible solid state integrated amps that works well with the Harbeth 30.2. This is a downsizing exercise and the unit should have a DAC and Phono Stage, both MM and MC.
My budget is anything less than $13,000. A Krell Evo 222 and Krell 302 was my previous setup.
