Choosing between 2 preamps

Quickie peek, I would pass on the BAT based on the comments about the Soviet Tube they use.

Atma-Sphere, I wish I liked it's looks because everything seems right! I wonder if they could provide a Stereo/Mono in addition to or even instead of Phase, and if not remote balance, then separate left and right volume controls.

$2200? Used? An MP3 is $5k plus new.

@noromance yes used with phono i think its mk 3.2/3.1.

Aounds too high? I don’t live in the US and all US gear is pretty pricey here.

@elliottbnewcombjr I didn’t understand if you talked about the visually look of the MP-3 , sorry.

also can you link me about the soviet tubes? It’s just normal 6h30 sovtek/ elctro harmonic from what i know.

yes, I was talking only about the visual appearance, and my desired features, atma-sphere's equipment seems top notch, from both their site and remarks from owners here.

if you get the serial number, then atma-sphere can tell you about it, including optional future upgrades if they recommend any.

I have the BAT VK-80 and I can assure you the 6H30 tubes are very good. Even much of the Audio Reasearch gear has used them!

I would work on speaker positioning. Your Audio Research Ref 75 has plenty of power for your speakers. Tube amps like this are very powerful. They have deep and nuanced low end. 

@ghdprentice those were not my speakers.

my speakers Sonus Faber Electa Amator 1.

but I am right now looking for a preamplifier (i dont have)

and I can’t audition these two at home…

can you share with me your idea between BAT and Atma Sphere

I saw this right after I joined the forum

Ralph has replied in generous detail in many discussions I read, including to me when asking for advice here.

I’ve heard the Atma-Sphere (but not the BAT.) and it’s darn good. @atmasphere service is second to none so you’re safe for service and upgrades. Going from 3.2 to 3.3 + VCap is a worthy upgrade.

Maybe you should look at locally made preamps?

I'd pass on both and consider the Audio Research SP-14 that's listed on eBay right now for $1400.00.  Especially since you have an Audio Research power amp.

I don't have a horse in this race, and I'm not getting anything from the deal, but this sure looks like a great deal on a preamp that's definitely top-tier. Stereophile said 

'In my opinion, the sound of the SP14, via line or phono, will set new standards for the industry. I can see other companies using the SP14 as a benchmark by which to judge their own products—it's that good. It is user-friendly and attractively styled, injecting its unique form of magic into the reproduction of music to a degree I've rarely experienced before. I feel it should be included in Class A of "Recommended Components." It is a very special product."

@panzrwagn my amp ihas only xlr inputs.
