Preamp suggestions for Atma-Sphere Class D Monoblocks


As I impatiently await the arrival of my Atma-Sphere class-d monos, I am writing to solicit opinions from experienced members on this site. Balanced inputs and outputs as well as the ability to connect a subwoofer are important. Headphone amp would be nice but not critical. Ditto for built-in phono. These are some of the tube and solid state units I am considering (not necessarily exhaustive):

  1. Atma-Sphere MP-3 mk3.3
  2. Cary SLP-05 (ultimate edition, if I can find a pristine used pair at a good price)
  3. Modwright LS-100
  4. PrimaLuna EVO 400
  5. Supratek - Champagne or 6SN7 Cabernet - I have no idea what the difference between these two are and the website is not helpful at all
  6. Anthem STR
  7. Benchmark LA-4/HPA-4
  8. Bryston BR-20 (or one of their purely analog variants - BP-19?) - I am hesitant to bundle streaming and dac into a preamp
  9. NAD M66
  10. ?

I will initially use the Bel Canto DAC2.8 as a dac and preamp with an Auralic Aries G1.1 as the streamer. My speakers are Totem Acoustic Forest Signatures, sub is a REL s/510 that I seldom use. I am unsure whether I can use the speaker level connections with the A-S monos (my current Bel Canto Ref510S class d amp has a chassis grounding screw to which I connect the REL’s ground wire).

Philosophically speaking, I have owned a wide range of equipment over the years - everything from "measurements above all" type gear (a full Benchmark stack), a few tube pieces (PrimaLuna, Tavish Design, Rogue), Class A amplification (Pass Labs XA-30.8) and a completely active Genelec 8351b based system. I seem to be slowly but surely gravitating towards subjectively great sounding gear, regardless of how they measure - the Totems are a case in point. However, I don’t want to find that I have moved too far in any one direction. At the end of the day, I value realism and emotional connection more than the ability to deconstruct the music but I don’t want to listen to a sloppy system that homogenizes everything. I’m sure this is all clear as mud! It is however, a reflection of where I am at the end of 28 years of being on this hamster wheel. All thoughts and suggestions welcome. Thanks in advance.

@  srama    I have owned the A-S MP-1 for 20 years and just got it back from being upgraded to 3.3 status. Ralph finally got me to agree to it after 10 years of subtle persuasion. All this time it has been paired with his M60s. A friend of mine has the MP-3 (not upgraded) paired with MA-1s and I have been listening to it routinely for at least 10 years and have had it in my system a few times. I am here to tell you that the MP-3 is fully 90% (maybe more) of what my preamp is sonically and requires only about half the tube complement mine requires. It is truly balanced and  represents one of THE great hifi bargains in preamps. Buy it and don't look back. The fact that you will simultaneously establish a relationship with one of the most knowledgeable, caring and responsive bunch of guys in all of audio and will be buying American is just the cherry on top. Enjoy!

High praise indeed! I value your personal experience hearing the MP-3 in your friend’s system. I just placed an order for an MP-3 with the V-CAP and chassis damping upgrades - to say I’m delirious with anticipation is understating it!
