Preamp Deal of the Century

.
Sorlowski,
.
I have the Rollerblocks placed under both the Pre-Amp and the Power Supply.
.
The Rollerblocks are placed in direct contact with the bottom plate of the boxes (not in contact with the rubber feet).

My only disappointment is the amount of ‘sweetness’ in the midrange, would like some more of that. Three questions for my Supratek bretheren;
1) Any NOS tubes that’d exchange some bass response for more midrange sweetness?
2) what would be an appropriate level of turntable for this phonostage, I was thinking MMF7 or something in that strata – can I go for a less table like the MMF5 or would going up the food chain be the hot ticket?
3) the power supply tube is only an inch from the next shelf and the bottome of the shelf feels very warm to the touch. The rack is open on all sides. Cause for concern ?

1.) Sylvania VT231 have a sweet midrange and less bass punch as well as RCA VT231 in my system. The EH 6SN7 though sounds wonderful as well and does not command the outrageous NOS tube prices.

2.) I would recommend a Teres table. Also, a Denon 103R while you are at it with a high mass arm.

3.) Although it will take an enormous amount of heat from the tubes to burn your shelf even at an inch away which is impossible to achieve with the 5AR4/5Y3 type tube, peace of mind is the thing that really matters here in the long run.

cheers

Richmon: With your concerns about heat, just stick a 4"x4" square double layer of aluminium tinfoil (shiney side out) under the shelf above your power supply tube, it should act as a heatshield. Since you have an open sided shelf, heat build up shouldn't be a problem.

Slowhand: I agree, the Supratek phono sections are a real gem! My turntable with Koetsu Rosewood cartridge murders my digital front-end consisting of Sony XA-7ES + Bel Canto DAC-2. Digital sound is nice when listened to in isolation, but just doesn't stand up to an A-B comparison against analogue...

Thanks for the feedback lads, hard to believe that the phono will be even better than the line output, Jimi Hendrix was in my living room last night, playing the 'experience Hendrix' CD remaster of Electric Ladyland. Found myself in the kitchen between CD's muttering to myself 'damn that sounded good, damn that sounded good' - if the LP playback gets even better, scarey to think what I'll be mumbling about next.
My concern about the heat build up around the power supply tube was more about tube life, not actual fire.

Richmon,
I'm in a similar situation, as you are. I recently bought a new Chenin from Mick M., and wanted to share my impressions.
When you say:"amount of ‘sweetness’ in the midrange, would like some more of that."- I'm not exactly sure what you meant, but what I'm hearing, is the slight emphasis in the presence region (voices especially).
It does make it sound very "alive", but on some recordings it becomes too forward, boardering on irritating.
Again, I like many things, that Chenin does excellently, but it defenitely will not let you " to sit back and relax", it requires your full attention.
And to me it's becoming a matter of personal preference in a sense what one expects from the listening session- relaxation or kind of an "analytical" and "wow" experience.
I should make a few reservations though:
My Chenin is new and likely is not broken-in fully
My source is digital (Modwright tubed Denon 3910)
And my impressions are of course relative to my previous pre-amp McIntosh C-45.
I would love to know if anybody else shares my impression of Supratek midrange?
Also, what tube(tubes) can make midrange to sound more "recessed" if you will.
