Atma-Sphere MP1 with single-ended inputs and outputs? Adapters OK?


I had the opportunity to hear an end-game system (for me) that was fronted by an Atma-Sphere MP1 preamp and their Novacrons.  I was blown away by the overall sound, and am highly considering starting purchases toward that system for myself, but had the following questions I'm hoping someone could answer.

In short, the purchase path for me is likely going to last 18-36 months, given the costs of the various components and speakers, so I'm going to have to be living with "hybrid" systems for that time period while I spread the purchases out.

My current weakest link is my pre-amp (although it's not weak, but...).  If I start with the MP1, both my source material (VPI Classic turntable) and amps (Thoress 845 SET monos) are single-ended.  I'm sure I could get an appropriate balanced output for the VPI (I think?) and my DAC already has balanced out (which is my only other source), but what loss in sound quality will I experience adapting for singled ended RCA connections out from the MP-1 to my SET monos?  My current set-up has short (1.5M) runs, so the length of cable won't be an issue for me in single-ended.  But will using something like adapters or the tape outs on the MP1 negate any sonic benefits of the MP1 I might otherwise be getting for the time period I'll be using single-ended amps?  BTW, I LOVE the Thoress 845 amps, so they will likely be the last part of the chain I will consider replacing, and I may choose to keep them in the end-game system depending on the synergy.

Thoughts or experience with the MP1 and single-ended output?

I think RCA output to XLR input cable will be safe, but XLR output and RCA input will be careful.

So what is final solution for RCA pre to go xlr  only  power amplifier? The answer is passive preamplifier with XLR output.

You put that passive preamplifier in between your  RCA pre and. The power amplifier, that's it.

Get high quality one to match your RCA pre.

 

I use the Jensen isolation transformer, and the sound lose a lot of detail.  I think the isolation transformer should have gain volume control and let you get the right gain after the transformer, as the signal will become weak  if no gain increase and that's the reason I give up the way to use Jensen isolation.

The one I got is defective one, when I connect it ,just less than 5 minutes later, strong noise coming from the speakers even I shut down the volume.

I am discussing with Jensen for return.

 

I got return and refund of the ISO MAX transformer finally.

It has strong noise for my system, I do not know how other's situation.
