I have had many amps in my system, but none drive my Eggleston Andra 3 with more ease and let the speakers breathe in a way one think impossible before having heard it! Fantastic amps with enormous headroom, quietness, debt. Theres details foremost in the lower regions i have not heard before. People often tend to focus on source, cables, other tweaks, but not having a good amp can force you into problem soulution where theres actually no problem. A great amp is basis for a good setup; with this you cant go wrong!
It is expensive yes. is it worth it - well for an Audiophoile YES!
