It's all about the tone.

Sorry that I haven't been more clear about this. I'm a music lover first and audiophile second. Some of most intense experiences I've had have been with live music, and my tweaking efforts have always been directed towards capturing more of the tone of live music in my system. When I installed the Raptors, I was captured by the gorgeous tones present in my favorite recordings.

RF noise is the major cause of harsh, cold tone in serious playback systems (along with the usual other issues), IMO. Switching amps that contain switching power supplies are compromised by the proximity of the supply. The Raptors are based upon oversized linear supplies for this reason. My OTL amps could approach the Raptors for good tone, but were more susceptible to RF noise from other sources than the Raptors appear to be.

The chip technology is proprietary, but is made by a well-known manufacturer. The assembly is done by a first-class military-qualified house.

I haven't had the amps long enough to say that they are tweak-proof. They perform so well that I've been busy cleaning up some now-obvious problems with my CD player AC supply and interconnect cables. I've found some slight resolution dependence on the details of the Raptor power cords, but that is all.

The amps use toroidal power transformers, and, like all such transformers, will buzz if the AC has enough harmonic distortion. I can tell when my neighbor uses her hair dryer on half-power! Fortunately, that is the only local AC harmonic distortion issue that I have.
