Thanks guys. I managed to borrow a Son of Ampzilla 2 from a friend. And just coming out the gate, barely warmed up, it is clear that stepping away from the Class D monoblocks is my direction.
Hattor Ultimate Power Amplifiers
I am wondering if anyone has tried Hattor Ultimate Power Amplifiers? I am currently driving Martin Logan ESL X speakers with a pair of Nuprime STA 9s as mono blocks. I am happy mostly with the soundstage and detail I am getting, but I am experiencing a little harshness at very high volume and I am wondering if next level class d will afford more musicality and punch. Anyone with experience going up the food chain in class D amplifiers have any insight on this? Thanks, Tom

By the way, I am thrilled with my Khozmo mostly passive preamp. Arek added a simple stepped attenuator to it for me because I needed a little more gain in my system. Arek at Khozmo was a delight to do business with also, just awesome customer service. I have had other serious preamps in my system, from Berning to Superphon, and this Khozmo is my keeper. It is so clean and simple and it lets the music bloom. My original post was really about whether or not to go Upstream to the $3K to $5K class D amplifier level... and for now i have made my decision... A/B. |
Class D is not an optimum match for electrostatics.middlemass and mijostyn are correct tomflynn OP , Class-D really dislike driving 1 ohm loadings in the highs, and that is what the Martin Logan ESL’s present, and a heavy negative phase angle –68.81º at 5.9 kHz together with 4ohms loading.
