Oh how I wish Class D amps ...

" Any of the class D users driving a pair of soundlab speakers;if so whats your opinion?"

A friend of mine with soundlab (latest A1) have auditioned my Wilson's Sasha driven by the pair of Spectron monoblocks and also bought the pair. (He used to have Pass Lab X350.5) I love the sound of his system and so does he.
Pass Lab, rather suprisingly for me, sounded "grayish" or "grainy" with shallow bass and very little dynamics in comparison to Spectron. I suspect this is only because these electrostatics demand power and power and power and Spectrons have about 7kW peak power.

" ...the bar that has to be met by class D is not how they compare to traditional transistor designs but (especially on SoundLabs) how well they compare to tube amplification. "

Hello Athmaspere. I don't like to put all amps together into single group as "class D" and even more tube amps.

I mentioned in my post Spectrons and Wayne Donnelly, reviewer from Enjoy The Music, sent back his $50k VTL Zigfrieds (spl) when he got his Spectron. I also much prefer Spectron over my former amp, McIntosh 2202 etc

On other hand, I truly love OTLs - your and that of Jud Barber of Joule-Electra but I can't stand their heat and high maintanence. Moreover, only you know how well your amps can drive Soundlab (I suspect very well) but 100% they cannot drive my Sasha by Wilson and provide the same dynamic range as Spectron does - Sashas are the most power hungry speakers in entire David Wilson line.

" Mike do you think Ralph's MA2 or MA3 could drive those speakers?"

Hello Rlff: I think this question is best to be addressed to Ralph...

Atmasphere, least of all I want to argue with you. However, I did not expressed any doubt that your "bigger" amplifiers (or similar OTL amps) can drive Sasha too. Surely, they will show magical midrange there as well.

I love to audition operas e.g. Saturday's "live" transmissions from Metropoliten Opera in NY, big symphonic music and I do stand behind my statement that any OTL I know of: "cannot drive my Sasha by Wilson and provide the same dynamic range as Spectron does ". PERIOD !!! I believe Spectron has 7kW peak power and it shows!

"Verdi's Requiem, track 2, Dies Irae" Oh yes, sir !!!!!
The biggest dynamic range I have experienced when (at holidays only) I use Sony early SACD where Eugine Ormandy conducts Philadelphia Orchestra.

I stand corrected - live FM transmissions are probably compressed, indeed. However, when I see them in my own listening room singing and talking and I am actually away hundreds of miles away and did not pay hundreds of dollars for ticket - my knees are shaken !!!! It is the best system in my life, system which transfers me there (or them to me - I don;t understand he difference) sometimes so realistic I almost cry...

You are great man Ralph! and you undertsand us "obsessed" as few can
