Which high power SET

Edoit,
That's a very nice list you have. There's a Shindo GM 70 SET available here on audiogon, surely a fine mate with your Masseto. Yes, some excellent choices to pick among.

Edoit,
Atmasphere makes a good point and his reasoning is sound. However if there's any chance you can hear one of those premium SET amplifiers with the speaker, please do so. From personal experience I can say that expectations aren't always reality. Those are "very good" SETs on your wish list. Depending on your taste, music genre,room size and listening volume they could be just what you want.Compare them to a higher powered(pentode tubed) push pull amp and decide. You may be pleasantly surprised by what you hear.DHT tubes are capable of producing beautiful natural sound.
Good Luck,
Charles,

Larryi,
Many good points you've made as usual. I agree that no single amplifier or particular topology is perfect, they all will require some degree of compromise. The key to ultimate success and long term happiness is knowing what type of sound/presentation you truly want. I stuck with the SETs since this is what Edoit expressed interest in. I believe that he's headed in a very good direction with his list of candidates.

Edoit you say that you current 30 watt amplifier is enough power and pleases you, that's important information to know. Based on that I'd strongly urge you to listen to the 845 SETs you're curious about. Given your comments it suggests that high quality 30 watts is satisfactory with your speakers. Quality will often win out over quantity with the appropriate speaker match. As Larry said an OTL is a viable option (they all sound different depending on the brand).Personally high quality SET amplifiers are the closest I've heard to mimicking the live venue experience. That's why I'm very supportive of your pursuit of them. Naturally YMMV.
Best regards,
Charles,

There are enough existing variables involved that a solid argument can be made for numerous opinions. Edoit's typical daily listening levels will determine so much about successful amplifier selection. We all can agree that an in home audition is the ideal solution.

It hasn't been established that the Harbeth is incompatible, just speculation. Edoit is doing fine with his present 30 watt amplifier so a similar power SET is at the very least worth an audition. Either he'll like it or he won't. Listening is the only way to determine this. It could disappoint him or reveal a honesty and realism he's not heard before. Let the ears decide.

Pani,
I appreciate your comments but I must agree with Jwm (Jeff). He and I have been good friends for many years and have heard numerous amplifiers in our respective systems the past 22 years. VTL, ARC, CJ, VAC and on and on. His 845 PSET is simply superior sounding and far more natural than all the previous amps mentioned in his home. The VAC IMO was the best of the push pull amplifiers he had. Even the VAC PHI 300.1 mono blocks were out done by his sublime performing Absolare Passion amplifier. Jeff like many others was skeptical about SET capabilities, not any more. Pani your opinion is just as valid as ours, the point is that we all hear as distinct individuals.

Hi Clio09,
Not sure if you've read the entire thread. Earlier posts have mentioned room
size and listening levels as important variables that must be considered. As
I told you at CES this year, your amplifier was terrific sounding.

Keithr,
I enjoy these types of discussions as they highlight the marked differences and conclusions we form. I still own an el34 PP amplifier that's 40 watts ultra linear and 20 watts triode mode. My 8 watt 300b SET literally embarrasses the PP amplifier with my speakers. This is vastly different from your experiences but that's how it goes. We all have varying outcomes. I'm in the minority here and that's okay, I respect all the participants here. Maybe I'm the oddball but to my ears SETs consistently sounds better because they are more natural and realistic. Needless to say, YMMV.Edoit "listen" to your Harbeth with your list of fine candidates.

Charles,
