Atma-Sphere S-30 MK3



To Atma owners and gurus;

I've just recently jumped on the Atma wagon and I must say that so far this has been the single most eye & ear opening amplifier experience in my entire audio life of almost 28 years.

The S-30mk3 has been residing in my rig for close to 4 months now and is still breaking in, but should be almost done anytime soon.

I do however complain of an un-natural tonality in general that comes and goes during the break-in period and which was also very clear from the beginning. This is also accompanied by a certain 'hardness'..much like looking directly into sunlight as opposed to looking through a pair of poloroids..This issue is really bugging me and was wondering if it's part of the break-in process of Atmasphere amps in general, as I have never experienced it with other amps, tube or SS..

This aside, the amp seems to be taking forever to break-in..!!! But, it certainly looks to be my holy grail in amplification.

Along the way, I replaced the stock Chinese 6SN7's with EH's and now settled on Tung-Sol's. The latter being the best sounding of the lot. I do wanna stick to current production tubes as much as possible. Don't wanna go on the NOS merry-go-round..:-)

The S-30 is driving a pair of Tannoy Edinburgh's, from the Tannoy Prestige Series, to wonderful effect and the sound is heavenly! Preamp is a BAT VK-3iX Special Edition and is also a very good sonic match with the S-30..

Appreciate any input and of course any advice from the Atmasphere gurus and lovers here..!

TIA

If I may to offer a differrent perspective.
This discussion sounds utterly familiar to one , that took place in the infamous "Preamp deal of the century" Supratek thread, regarding "glare", that some Supratek owners (myself included) heard in very different systems, that employed Supratek preamps. Our impressions were very similar, but at the same time an obvious minority. The vast majority of Supratek owners couldn't understand what glare we were talking about, and the general consensus in the end of that discussion was pretty much:" Majority of esteemed and experienced A-gon members didn't hear the glare, and the small number of owners, who did, obviously didn't know how music is suppose to sound".
Fast forward from my Supratek phase, and after having some other preamps in my system- Doshi Alaap, and now I have BAT Rex with BAT-75 SE (graciously lended by a friend), I can say with a high degree of certainty, that I just confirmed my impressions of Supratek as very colored, bright and definetely exibiting glare in the upper midrange (not at all dissimilar to "looking directly into sunlight).
To sum it up, my point is this- I think we all have different sensitivity to certain parts of the audible frequencies, especially upper midrange, treble.
It can be attributed to the age differencies for one, and to a multitude of other physiological factors as well.
BTW, I retrospectively think, that Supratek's "glare" is attributed to silver-plated copper internal wiring, used in the chassis (it's point-to point wired).
Now, I'm sure, many will conside my post rediculous, and will continue to defend their own listening experiences, as "the one and only truth", which in the context of one person's hearing abilities, is such.
Ralph,
Very informative, as always.
When you said:
"All our products are built with a custom copper wire that is as pure as anything else out there- by rights, we could be cable company ",
I wonder, if you have found silver-plated copper wire to sound different (read glare), than pure copper. That has been my personal experience.
