Hybrid Amplifiers suggestions

Lamm Industries M1.2 Reference monoblocks are a pure class A hybrid design and have been an industry benchmark for a decade.

Ypsilon’s Aelius II also comes to mind.

Heads up that I’m a Lamm Industries dealer.

Cheers,

New York Audio Labs (NYAL) made three excellent hybrid tube/MOSFET amps back around 1990. The Moscodes 150, 300 and 600. 75, 150 and 300 wpc. Designed by George Kaye and built in NY State. I have the Moscode 150. They differ in the number of output devices used. There is a review of the Moscode 300 in the Stereophile archives. It made the cover of that issue and got a favorable test by Atkinson. All the models use 2 input tubes per channel: a 12BH7 and a 12CG7/FQ7. I recommend buying one of these over any more recent ones!

Van Alstine makes FET Hybrids!

Thank you all for your suggestions, keep them coming! 

The two I am thinking of both have Class D output stages rather than a MOSFET Output stage.  
The AVM A5.2 and Canor Audio AI 2.10 are both awesome amps but require you accept Class D.

frank is one of the original no BS guys in the biz... puts $ into the sound quality, not the bling factor

truly well designed, truly excellent sounding gear

no affiliation, just a loyal customer many times over

Pathos Acoustics. 

I have the Classic One MKIII and love it. Upscale Audio is the US distributor and great folks to do business with.

Had a Raven Blackhawk and had issues from the start. Have Raven CeLest Speakers and they work great with the Pathos. 

Folks, I have decided to keep things simple and going to keep the amazing Accuphase E-650 Integrated in my system.

Thank you all for chiming in :-)

Nice

I wasn't impressed with the Rogue Sphynx 3. Descent amp, but all I heard was class D. Don't take my word. Just my taste and observation. I was surprised due to the good word on this one.

that accuphase is beyond reproach... enjoy
