Sanders ESL Power Amp & Mono blocks


I would be interested to hear feedback from users of the Sanders amplifiers. In particular, why you chose this amp and what else you considered at the time? Further, did you also acquire Sanders Pre-amp or opt for another manufacturer? If another manufacturer who?

I have some power hungry full range planars (84dB sens) to feed.

Ah, some more Sanders amp users...

Why? Well it has one of the purest mids-highs I've heard from SS amps, while retaining the grunt in the bass. Its like a marriage between v good SE tube w/o the euphony, and powerful clean SS bass.

What else? Nothing really. I only consider changing equipment when it is able to move me, draw me into the music. Otherwise I don't really bother. I'm mostly a tube guy, so getting this amp really speakers volumes about its musicality.

Opted for the ModWright SWLP with NOS tubes. Heard the Sanders pre, but I couldn't warm up to its sound.

I don't agree that this amp is meant for digital, that would be very obtuse. The amp is extremely neutral and clean. It would therefore reveil whatever warts or beauty there is from the source.
Hi Kiwi

Well whether it is the Cabasse @92db/w or the much less efficient Vandersteen 2CE SigII @86db/w, the ESL stereo amp had the same basic neutrality about it. You don't get the "edge" or digititus when listening to CDs. While the 2CE SigII has the upgraded tweeter, it was a significant degree smoother and controlled with the ESL amp driving it. How I ended up with the ESL amp is because I loved the purity in the mids/highs, in many ways similar to the much more expensive Dartzeel amp.

I also had the opportunity to hear the ESL Monos driving the big Dynaudio Evidence Temptation, which aren't exactly easy loads despite the 90db/w rating. It handled these big speakers with ease and had tremendous control off the woofers. You can hear this when the music gets complex at fairly loud SPLs, and it doesn't break up, or show stress as in muddling of the soundstage.

The dealer which sold me the Sanders also carried the ModWright, so it was a natural choice. Perhaps I should have waited for the 36.5 with the separate power supply, but the price difference pushed that out of my budget. However with the NOS Amperex 7119 in place of the 5687 tube supplied in the SWLP9.0, this pre takes on a very special presence and transparency which is very hard to surpass.
Hi Kiwi

Well I heard both combinations at the dealer's showroom. The Sanders is typical SS sound, very clean and leaning towards the lean/thin side. The ModWright had more body straight off, but does not sound euphonic like older generation tube amps. Perhaps its me, and you might want to get another opinion from Cerrot, who has the complete Sanders system.

You are right about the balanced operation which IS a good thing with the ESL power amp. I did try driving the amp direct via the balanced outputs on my Benchmark DAC, and it was a marked improvement over the SE connection.
