Fjn...for sure there's no harm in questioning an opinion, that's what this board is all about. My opinion is really only valid for my experience, and am sure that others have different opinions when hearing the same things.

I've heard Devore speakers with a variety of different amps in the Leben/Devore lineups over the last few years, both at the Montreal audio show and at Coup de Foudre. The Shindo combo they usually have on display at the store (when they can keep them in stock) has been Aurieges/Montille (though I may have heard other combos at other times - when the Shindo wasn't something I was looking at buying, I wasn't paying as much attention to model names, though I do remember listening once to a Giscours preamp), and at the audio show they've tended to bring Leben integrateds with the Devore speakers. So...my experience isn't scientific, as the room is a notable variable to consider.

With the P/E's, I do usually run my amp in tetrode as you mention, but for smaller scale recordings switch it over to triode. When I was comparing the ST150 to the MB125 EL-34 monoblocks in my system, the added power and control of the ST150 was a significant enough improvement that the triode mode had sufficient power for most types of music. But I still use tetrode about 75% of the time.

BTW...nice system that you have there. Do listen to the Leben amps if you get a chance one day, I'd be interested to hear your thoughts in comparison with the Shindo that you're used to.
Countingbackwards- my reply from the other day mysteriously vanished, so I thought I would follow up. Perhaps something I wrote was not approved by the moderator. I did leave my e-mail address, so perhaps that's the reason. I would like to think not, but can't imagine what else it was! I appreciate your response. To be frank, I wanted to know if your opinion was based on hearing the preamp and amp. I have been to CDF a few times. I have no affiliation, but have to mention they are a great bunch. They all seem truly passionate about this stuff.
I've heard those Nines many, many times, with lots of different equipment - all Shindo, Leben, Shindo-VTL (which I've also hear with some Wilson speakers and, of course, my own), and probably others that I don't recall. They're kind of my "go-to" speaker at this point at CDF, as I'm comfortable enough with them that I can get an idea of what gear does when I hear them. But of course I haven't done any strict "comparison tests" with any of this gear - I've just listened for enjoyment.

IMHO, the Nines are capable of an astonishingly high level of detail retrieval in the midrange, but are less refined at the frequency extensions, which are subtly rolled off in order to mask that deficiency. That's a pretty good way to design a speaker like this to be excellent in one area, without really having any audible downsides.

My point with all this...every piece of gear with a more developed, detailed midrange makes these speakers sound better, because those assets will shine right on through the speakers. I would be aiming for increases in midrange detail and texture with every piece of electronics that I buy for Nines (which I came quite close to buying before ultimately going with the Parsifals).
Interesting no one mentioned Harbeth! I've heard Leben and Harbeth, this setup synergies on a different level. Transparent amp with warm speaker equals musical bliss. Plays emotionally sweet with all types of music.

Keep the Shindo with Devore. This makes all your music sound old school. Good for the masses but not for me. Occasional listening to rock'n roll can't be sounding old school and romantic. Go figure. Warmer amp with neutral speaker, that's shindo with Devore. Sounds very natural, but keep the rock and techno genre off your listening sessions.
