Who Offers a Highly Musical Preamp using a 6SN7 tube and a remote?

I think the XA25 single ended and wouldn’t benefit from a balanced preamp. I’d recommend on LTA microzolt Preamp.  I own one and love it.  And they can use 12sn7 or 6sn7 tubes.  I know I’ve read about the combo of the LTA and pass/first watt amps.  

Anyone heard the Erhardt preamp?

or Atmosphere UV -1 ( reviewer found it grainy )

I own one, and 'grainy' isn't a trait I would ascribe to it, in the least.

Quite the contrary. To my ears, it outperforms many preamps, even ones that are higher priced.

@armstrod is your Atma-sphere MP-3 “stock”, or does it have upgrades such as V caps or Caddock resistors?
