New Classe Delta amps and stereo pre amp

If Class D. ?
no thanks

I am curious, too; though I think their pricing has moved out of my bracket.

If Class D. ?
no thanks

Not likely, with this kind of bandwidth
1Hz – 650kHz

and weight
102.3 lbs (46.4 kg)

and ability to increase wattage from 8ohms to 4ohms to 2ohms
Stereo
250W / 8Ω
500W / 4Ω
350W / 2Ω
Monoblocks
300W / 8Ω
600W / 4Ω
1000W / 2Ω

No Class-D could do this sort of doubling.

The amps are not class D. The preamp seems to be a significant update of the CP-800; by which I mean, similar features + phono. The MSRP if $12,000 is twice as much.

These amps are made in Japan by the same company that owns Marantz. They claim the new mono amps run up to 35W in pure Class A whereas the stereo delivers around 25W in Class A. Looking at the design it is very clear it is indeed a class AB project with proper class A bias, particularly on the fan-based cooling system it employs (!). I am unsure about the sonic effects of that solution on the overall performance, as critical as overheating is for this kind of topology.
The preamp features an analog section (volume control, RIAA inputs etc) and a separate digital section with dsp settings, which is very interesting for someone like me figuring out how to integrate HT and stereo optimally - an optional HDMI board is offered as well.
