Unison Research S6 vs S9 vs Sinfonia

Hi,
I am evaluating some higher powered SETs for my 93 db sensitive Tannoy Turnberry SE speakers. These Unison Research models are quite appealing. They all seem to have a healthy power output of 27 to 35 watts in pure class A single ended mode. I heard the smaller Preludio and I was very impressed with its rhythmic and lively presentation. Has anyone heard the bigger models, especially S6, S9 and Sinfonia ? Which of them would be the most dynamic all-rounder ?

I am worried that the bigger models like the Sinfonia and Performance have much higher level of negative feedback and that could take the magic away, that's the reason I wanted to know if anyone has heard preludio and the higher models. I listen to a lot of big band and classical music so dynamics at reasonably loud volumes is very important to me.

Dear Pani,

We have the S6 on display and it is a fantastic amp, given the right speakers it is just magical. The S6 will work woinders on your speakers and will not run out of steam. The S6 drives most of our display speakers which are 86-90db surpisingly well.

The soundstage transparency and clarity and musicallity of these amps is top notch.

Hi,
I got the S6 mk1 with LaTout tubes on Living Voice OBX-RW with 94Db sensitivity, and it has lot's of power left. The S6 mk2 is much better then the mk 1, and according our importer the Sinfonia gives you much more on all fronts, and is less fussy as the S6.

Pani the Preludio, is a bit more powerful and has more kick, it doesn’t have the same sense of  presence of the S6.

As long as you dom’t push it the S6 is awesome sounding.

Please PM if you want more details.
