Looking for a new Amp or Preamp? If you're after tubes, post over here.

RE: "While not perfect, it is still better then anything else available" seems you forgot to add IMHO...nt

As I mentioned in my post to start this thread...the problem may not be so much the device...although even the VFets and screen driven 509s are not as linear as a good DHT, but using it in push pull. So, Nelson's SIT amp might be the answer but even that, I am told, doesn't converge with DHTs. It is also power limited.

I got pretty close with my NAT Symbiosis, which was a Class A SE(T) hybrid. Input and driver were tubes and the output was a single big industrial MOSFET mounted on the bottom of a vertically mounted monster heatsink. It delivered a true 100 watts of Class A power with no negative feedback and had the tone of a nearly perfect SET and SS like bass control and drive. HOWEVER, it was still missing something that was difficult to pin down and in the end I preferred true SET amps over it. I wish I could find some measurement data on it but there seems to be none because it was probably close to ideal but missing in a key area.

In terms of imaging it was more like great SS than holographic 3d.
