Tube Pre-amp Suggestions.

Fezz Audio Sagita Prestige - fully balanced tube preamp for $3495.

I am very happy with my PSAudio BHK pre. ChatGPT ranks it as my best component and wants me to replace my Moon 330A with your Coda #8, as it thinks the #8 is a perfect match for my system. 
It follows the BHK would match very well with your Coda. 

You guys are awesome, thanks!

I guess it depends on your objectives Solid state or Tube based pre. I suppose your BHK offers a little insight into tube pre amps. I use a EamAR Yoshino 912 which is fully balanced All transformer coupled and has an absolute pearl of a phono stage.You could also consider the EAR 868L or PL if you want an excellent configurable MC  capable phono stage.

To all the respondents recommending and/or using 6SN7 based vacuum tube preamplifiers:  try a set of Sylvania triangle plate 6SN7’s made in the late 1940’s and early 50’s. Something special, and in my experience, low microphonics (not always a given in octal base small signal tubes).

My recommendation would be the Luxman CL-38uC if you’re seeking a full featured tube preamplifier with bulletproof built quality and stunning retro looks.  Transformer enabled balanced in’s and outs, a great phono stage with SUT coupled MC inputs, mono switch, variable turnover tone controls that can be bypassed, and a basic remote.  I know it’s out of your budget, but considering what it includes, the Luxman CL-38uC is a great value sez Art Dudley in his Stereophile review.
