Preamp recommendations for my system please

I have an Allnic L7000 SE and have no reservations recommending it.  Used under 10K.

I really love my passive dual mono pream Big Hattor

Try the Benchmark LA4 if absolute transparency is one of your goals. Prior to owning a Benchmark stack, I was of the belief that distortion and noise performance is not so critical. Turns out that notion is very wrong. I figure the reason that some low THD+N products sound mediocre is because they still suffer from significant crossover and intermodulation distortion, and channel crosstalk. 

Returning to tubes following a stint with the Benchmark gear reveals that those supposedly innocuous low-order harmonics are indeed a detriment, especially with respect to listening fatigue. 

Nice choices,what ever you pick ,you won't go wrong.

ARC, or Aesthetix, CAT, 

Thanks to everyone that responded, provided feedback, or provided suggestions.  I have decided to stretch for the Audio Research Ref 6SE.  Now on to cables.

Congratulations. Would be great to hear your impressions when you get it as as things break in.

The preamp will take a couple hundred hours to go through its largest part of breakin (~100 - 120 hours SQ can waver substantially)… after that it slowly gets better and better. While ARC said 600 hour for breakin, I actually found it continues beyond that… to about 1,000. I would hurry the first 120 hours… then just use it to achieve the rest of the breakin.

I would recommend waiting on interconnects and cables until all is broken in and you really know the sound. But I think what I say below likely to be a very safe route if you want to get it together more quickly.

When my system got to a very high level of performance like yours, the components have no flaws or nuances you do not want to hear and the best interconnects and cables become those that are as neutral and passed through as much of the signal as possible. To me these are Transparent. ARC and Transparent are a known synegistic combination. I also found their power cords to have a similar impact (don’t ask me why power cords would sound similar to interconnect… I sure have no clue). The only exception for me was the amp power cord. I liked Cardas Clear Beyond for that.

Benchmark LA4 or Wyred4Sound STP-SE - both offer similar design concepts and either one would be a great choice for a quiet and neutral presentation. Forget those tube things. They will not bring you the truth.
