Help recommend a good tube preamp

This pre amp shines in my system . . . very different approach. Hashimoto MC-10

The HM-3 is a simply amazing step-up transformer for MC cartridges.  We are not quite sure if it's appropriate to mention the HM-3 on this Web site because this step-up transformer can be a treasure not only for tube amps, but also for any audio systems that equips with a MM phono stage.  The basic idea of the MC transformers is to amplify the MC cartridge output signal to the acceptable voltage level for MM phono equalizers through a transformer - without an active amplifier.  With the HM-3, the sound image becomes very wide and deep with three dimensional representation.  The low sound is very tight and the high frequency is crisp clear.  In essence, the vinyl sound through the HM-3 is the closest to the real live music.

Any BAT preamp is good. Never had a bad one. 

+3 for the Backert Labs.

Aric Audio, point to point wiring, should last a lifetime.

Also Aric is a great guy, very helpful and accommodating.

I currently use a Atma-sphere MP-3.2 that I got used.  Only using it as a linestage with a Zesto phono pre and and a DAC.  Balance in for both sources and out to a Zesto Bia 120.  It's quiet, dynamic and not finicky.  Bad news for some there is no remote volume.  I was using a BAT before and while meeting all of your criteria, it was not as dynamic as the Atma-sphere.  I will probably upgrade and not because of the sound quality but user convenience.  There are only two prospects, a Zesto Leto or an Aric Ultimate.  I only need to balanced inputs and one balanced output.  Both the Zesto and Aric fill those requirements.  I'm leaning towards the Aric as the output level is adjustable via resistor steps and he's in my home state.
