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.
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

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.

Thanks tweak1. That is a nice deal on those monoblocks but it's still above my current budget. Luckily, the Son of Ampzilla MK2 I am auditioning is for sale and it is more in the range of what I can spend. I am going to listen for a few more days, but I am pretty sure I will be keeping this Son of Ampzilla MK2. |
