Is it class-D output stage, don't say and in pic. I fail to see any heatsinks, looks like a tube pre only.

Any good?

I think it's a Class D "Hybrid" similar to their larger Hydra and Medusa power amps. I owned the larger Medusa and it wasn't for me.... sounded a bit veiled and compressed compared to the all tube Stereo 90 Super Magnum amp and my Rogue Cronus Magnum integrated.

I was really excited to hear the Sphinx but came away unimpressed, and I absolutely love the 180 monoblocs and the stereo 90.

I know Rogue uses the Hypex UcD Class D modules but they modify the front-end with tube inputs and do something with the output MOSFETs.... or something to that effect from what I recall reading.

The design got a lot of positive press and praise but I didn't hear it that way.

Unfortunately, their "Hybrid Class D" implementation struck me as worse sounding than some plain-ole mainstream Class D amps that I have owned.

At the other end of the spectrum, I know that Rogue's all-tube amps are fantastic sounding and a great bargain. I had my eyes on the M-180's but then found a great deal on a pair of used Ampzilla 2000 2nd Edition SS mono blocks. But the M-180's are on my bucket list to try someday. ;-)

Maybe what you really want is Kronzilla.

Cool!

I've seen those tubes and they're much bigger than they look in the photos. I can't recall what they cost but they're not cheap.

Neat amp.

see my old review in Positive feedback...it is simply the best amp I have ever hear or had in my home.

I lived with KR VA350is for six years and they were nearly as good and will drive just about any speaker but the tubes are literally half the size and cost 1/4 the price for the tubes. I only sold them due to have a baby that I wanted to protect from the blazing heat of the tubes.

At 3% THD...I wonder what the real output is at the universally accepted 0.1% THD. Probably closer to 15 watts per side. It probably sounds good, so the 3% THD is not a huge deal, but I'd appreciate a bit more transparency (honest power rating) from the company...
