Integrated amplifier help

I have no prejudices I think vitus or the Ma9000 could be, does anyone have this coupled?

Vitus?  Aavik?

I have no experience with your speakers but after looking at the stereophile measurements there are various McIntosh amps and at least 1 integrated MA9000, that would drive them. I know people hate or love them, just another you might think about.

I have experience with the ML585 and Dartzeel Cth8550. I’ve owned a lot of very high end gear and find both to be exceptional products. I was a little biased against the ML expecting darkish and maybe somewhat boring sound. Reality is that it has beautiful highs with tight bass and mids/vocals as good as I’ve heard from any such unit. It’s grainless and very detailed.  I was going to sell mine to stay on the merry go round but decided that this would be foolish. These units can be found used in the 6-7k range used(list12k). In typical ML fashion the build quality and ergonomics are stellar.
The Dartzeel is great also but has a caveat or two not to mention the expense. Finally I would think that the Luxman L-509x should be considered but I keep coming back to the ML. I’ve never been more surprised at how good it sounds. In today’s high end pricing scene it’s a crazy stupid bargain at list price and folks are giving them away. FWIW

Thanks Al for your technical disquition, surely there is some truth in what you say. But I think that what is heard is true in audiophilia. that's why I wanted to hear opinions from those who have ypsilon.

I’ve heard Andy Pryor uses Gryphon amps (among others) to voice his speakers and that he himself is partial to Gryphon, so that might be something to consider.  Someone is selling a nice Diablo 300 on USAudioMart that could be worth a look.  Best of luck. 

If you don't think a Raven tube Integrated can work than you may want to consider Luxman or Gryphon.  

ypsilon phaeton integrated

That's some amp...

Whatever you get shop around, take  your time.

At that price point, you should be able to find a dealer you feel comfortable with, and help you. I wouldn't be on forums if I were about to drop that kind of dough.

I have no directly relevant experience. But if the impedance curve of your Avior is similar to that of the Avior II, as shown in the measurements section of Stereophile’s review, I would have my doubts that the Ypsilon Phaethon would be a suitable match.

The reason I say that is that the Phaethon has a specified output impedance of 0.5 ohms, which is not much lower than that of many tube amps. And as can be seen in Stereophile’s measurements of the Avior II the speaker’s impedance is in the vicinity of only 3 ohms at most bass, mid-bass, and upper treble frequencies, and is as low as 2.6 ohms at some frequencies. 3/0.5 corresponds to a damping factor of 6! That is vastly lower than the damping factors that would be provided by almost all other amplifiers having solid state output stages, which are the kind of amps I suspect the speaker was intended to be driven with.

Good luck. Regards,

Thanks for the advice on raven, but I think the integrated tube does not match the speaker. I was wondering if anyone has personal listening experience on ypsilon and avior or possibly darTZeel CTH-8550 Mk2? ...

That’s ^ quite the opinion. Another opinion might be to audition the darTZeel CTH-8550 Mk2 in this category along with the Phaeton.

What an absolute ugly brick of an amp. When I found the absolute sound review thought at first it was some awful AVR or something. Then I saw $25k! Seriously?!?!? Oh well...

For less than half that you could have more than twice that, and with out of this world beautiful looks to go with the gorgeous sound.

Its not even close. Not to mention its made in Texas.
