Which high power SET


I'm looking for a high power SET to drive harbeth shl5, using Shindo masseto pre amp.

Have short listed Verdier 845, Audion black shadow and Wavac MD805m. All three should drive harbeth sufficiently. Any opinions on the above 3 amps are most welcome, especially thoughts on matching with shindo pre amp.

Hi Edoit,

You're getting a lot of great advice here from some smart audiophiles. The common threads appear to be: 1) don't become overly enchanted by the idea of any single topology; 2) your speakers are ill-suited for SETs.

SETs can sound great; they also have real limitations. I've been running a sweet 2A3 DHT SET into 99db speakers (easy 8-ohm impedance, compression drivers) since 1999. It sounds really good in small spaces for quiet near-field listening. In my critical-listening room, however, where vinyl rules and I want realistic SPLs, it pales. That's with speakers designed for low-watt tube amps. Your speakers are not.

SET lovers tend to be very passionate about their choices, and they're on to something, no doubt. There's an infectious immediacy about the SET sound. But sometimes the passion takes on a metaphysical character that seems to imbue the topology with the ability to transcend the limitations of mundane physics, like adequately powering inefficient speakers with challenging impedance curves.

If you're certain that SET amps are your manna, I'd suggesting thinking about the amps and speakers as a unit, a single purchase, without trying to retrofit amps to your Harbeths. That way you have a much better chance of hearing the magic a SET *system* can make.
Pani, don't agree with you. I have a VAC 300 watt push pull mono blocks and my Absolare 845 mono blocks are better in every way. Less mechanical, more open, and much more natural. The VAC is great don't get me wrong, but sounds a little veiled in comparison.
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.
Charles,
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.
Charles,
Many have expressed that harbeths are incompatible with SET.
Is this a problem of topology (SET vs push-pull) or stated power?
I'm using a el34 push giving out 28 watts and I hardly go have to go past 9 o'clock on the volume knob. To my ears, the 28 watts seem more than enough for me in terms of power with good frequency extension.

If it's topology, it means harbeths with its low sensitivity are generally incompatible with any SET amp, irregardless of it's power output. Given a hypothetical world where both push pull and SET generate the same power output, does push pull drive harbeths better simply because of topology?
