I originally had my Magnepan 1.7s paired with a Peachtree Nova Preamp and a 220 watt amp and the results were good but nowhere near great. I sorta lost faith in class D amps and set my sights on a ‘McIntosh level’ amp however my bank account said ‘that ain’t happening’! Recently I upgraded to a Peachtree Nova 500 integrated amp and the difference is night and day.
There is a presence and detail now that I always knew the Maggie’s were capable of and the Peachtree makes them sing.
Class D amps have come a long way and more power helps too.
