Atma-Sphere vs. Supratek


I placed an order last year for a Supratek Cortese LCR preamp; it will still be a few months until it will arrive at my home in Silicon Valley. Meanwhile I keep reading good things about the Atma-Sphere MP-1 and Mp-3 instruments. Can anyone voice an opinion about those two brands, both hand-made tube machines in a similar price range? I listen to all kinds of music, including opera, mostly on vinyl [Basic 2200 Signature with Vector 4 arm and Benz Micro LP-S cartridge, Sunvalley phono stage with EMIA SUT, MSB Platinum Signature CD transport and DAC, LinkwitzLab NCore6 active crossover/amplifier, and Linkwitz LX521.4 open-baffle speakers (best speakers I have ever heard)]. For preamp I am currently using Ed Shilling’s The Truth. For me a natural-sounding soprano voice is the pinnacle of well reproduced music.

Atma-Sphere is in the USA, their are few Dealers whom you can borrow the unit from and have a home demo.

 

I own the MP-1 and MP-3 both with Phono Stages. Not heard the Supratek so cant comment on that,.

My Phono Stage in the MP-1 is dead quiet, if you use noisy tubes you’re gonna get more noise.

Nos Tubes dont work in the Phono Stage they are just too noisy. The Phono Stage runs fully balanced, i have balanced cable going into it. It is by far one of the best sounding phono stages i have owned. The Phono Stage alone has outclassed other standlone units that cost north of 20K so having both a Line Stage and Phono In one unit is a big plus.

 

If you’re encountering noise in the phono section try to use cheaper quieter tubes this has worked very well for me.

I agree on the Chassis its cheapy looking compared to others. However im paying for Sonics and Reliability not bling bling so it never bothers me much.

You can ask Ralph to build better Chassis for you thicker plates or what ever but be prepaired it will raise the cost much higher. Im more bothered about Chasis but i appreciate the Tech/Circuit Design and the SQ
