Tube integrated with real bass. Does it exist?


Let's assume it will drive two way speakers with 1" tweeter and 8" woofer, 89db 8ohm. Any price level. No hybrids invited.
I personally haven't heard of one.

Is tube power supply important or could be solid state?
Is tube amp with solid state power supply like QuickSilver M60 considered to be tube or hybrid?
PrimaLuna - Read this months Stereophile review of the YG Acoustics Carmel 2. Stereophile editor John Atkinson won't even use tube amps to write speaker reviews because they measure like crap but did not get satisfactory bass from even the Parasound Halo JC-1 and $24k MBL solid state mono amps.

He had a PrimaLuna HP integrated there for measuring and a review and recalled how well it measured and tried it. In triode mode, no less which is only 36 watts. And the results were so good that's how he finished the review. There's a thread here somewhere from a guy that said it was better than his McIntosh MC601 monoblocks which impressed me enough to buy.
Here is my list of tube integrateds with good bass to name a few..

- Viva Solista Mk3
- Vac Sigma 160i SE
- Einstein The Amp Ultimate
- Unison Unico 150 (tube hybrid)
My Ayon Triton integrated has good bass, at least I like it. The Kimber PK10 Palladian power cord helped too.
