Amplifier for Harbeth 40.2

Upgraded to synergistic research Galileo UEF speaker cables and has added more punch and more feeling to music seems like the solution for my system

You might want to add Synergistic or another brand power cord for your Pass.

 My new Mac MC462 works wonders with the 40.2‘s. 
It s the best amp I’ve ever heard with these speakers ( I previously owned the PS audio BHK 250 and the pass labs 250.8 ) and it is best app I have heard. Period
The MC 462 is one of three or four new generation power amps from McIntosh that feature several updates (including increased filter capacity) which  increases  clarity, dynamic range and bass control (among other things) which is very apparent when listening through the 40.2’s.(Check the mcontosh website)
 I think you would be hard-pressed to find anything better for the 40.2s under 20k

Look into the Digital Amplifier Company's (DAC) amp selection. I have had many different class A (Pass, ATC), A/B(too many to mention), and class D amps over the years. DAC's amps have a grain-less sweet clean tone, perfect bass reproduction, and all the power you will need! Plus you get 30 days to try them with a no hassle return policy!
