yet another tube preamp recommendation thread


hello, currently looking for tube preamp linestage upgrade recommentations.
recently tried an older cary audio slp98p f1 edition with new tubes. i do not need phono capability.
the cary had a lot going for it, an incredible midrange, very good bass and transparency, it just sounded unrefined and ragged in the treble on occasion, possibly due to the new tubes.
a new Slp 98 l with upgrades is a considetation.
also considering primaluna evo 300 or 400
and rogue audio rp7.
i value transparency, refinement and dynamics the most.
thanks.

you should look seriously at the KR P-135.  It is a 45 based preamp and throws out a huge sound-stage with tons of dynamics.  This is the review from Positive Feedback.

Full disclosure, I am a KR dealer but this is a pretty special preamp.  I would also suggest you look at the Art Audio Conductor but that is a bit above the price range you have listed.  It is highly customizable with switchable gain and it has an amazing headphone amp. 
I second Aric Audio! I have the original Motherlode with a Coda Model 16, and I have put the brakes on the the constant hunt for sonic bliss!
Avanti, if you want bullet proof reliability and service find a used ARC preamp. I know of units that are 50 years old and operating perfectly not to mention they sound wonderful. 
What sort of amplifier is being used- tube or solid state, single-ended input or balanced?
thanks to all so far. i am asking for preamps in the range of the cary slp98 up to the primaluna evo 4000/ rogue audio rp-7 or so, this is a rather specific price range.
i have heard of these preamps before but never had a chance to listen to the specialty and direct brands.
is the economy of scale such that they really sound better than the well established mainstream audiophile brands?
feeding a new parasound a21+ who's sound i really love.
