cost no object integrated amps

My brother has a Gryphon Diablo he got it for around $15 k 
I have not found anything at even low $20 k range that sounds that cohesive .
having the size to keep things properly isolated and premium parts quality when you are not under price constraints , like others mentioned less power cords and interconnects , and the synergy of the amp preamp in one chassis truly 
make sense .when he is ready for another upgrade That would be my end game setup.

I’m very happy with my Gryphon Diablo 300

Have you determined the wpc rating you want?

FEATURES.

no matter what, I would want both remote volume and remote balance. I find a squeak of balance adjustment from my listening position can make a big difference regarding proper imaging, and the sound simply opens up.

I want on, adjust volume, great, refine balance? click, done!

You may have remote balance in your existing pre-amp, but you might change that, might go back to a Vintage Tube unit, like I and many have done, losing any remote control.

Inexplicably, many new pieces, they often don’t even photograph the remote, and don’t list the features.

I had to download owner’s manuals and scour them to ascertain what had what, AND, sometimes it is buried deep in a menu.

compilation albums have individual tracks from all over the place, a track or two often benefit from adjustment.

I just bought as terrific album, high quality, it needed a few clicks to the left, then was wonderful

initially both drums were bunched up on the right, and Ry Cooder was weak on the left. 3 clicks, Ry volume up, and one of the drummers, his son, moved left of center. Just like the photo of them playing!

I started a thread, not the ultimate as you are lookin for, but about remote vol & bal

IMHO, Accuphase E-800 Integrated offers amazing versatility, build quality and feature set that easily puts many integrated in $30k-$60K range to shame. 

Mola Mola has just announced the Kula fully integrated 1 box solution. Kula can be ordered as a conventional integrated amplifier incorporating preamp, amp in the chassis or can be fully outfitted to include, preamp, amp, phono stage, DAC (with Roon endpoint) to have single chassis solution. Pricing ranges from $13,800-$25,000.

If in the market for one, I’d add these to my audition list :
- Analog Domain MD75 mkII
- Boulder 866
- Gryphon Diablo 300

Give the Ypsilon a hard look. A friend has a full Ypsilon system that is mind blowing. If the Phaethon is in that realm (I’m sure it is) it would be stellar.

The idea behind high end integrated amplifiers is to retain the majority of performance (sonic and aesthetic) offered by state of the art separates while simplifying the experience. A simple system with a set of loudspeakers, an exceptional integrated amplifier, and a turntable can be very attractive.

I have a darTZeel CTH-8550 Mk2 in my studio that sounds lovely and fits in with my clients' lifestyles rather than demanding they work around it. It's freeing.

@audioinfidel - do you own the ypsilon integrated?on paper by specs it looks slightly lower on the power side

@highend666 not about any game changer amp. but trying to understand the high end market on integrated amps.if any of the one's are as good as separates, it might be worth switching , considering the cost of good power and IC cables

That game-changer amp...

Ypsilon Phaethon
