Tube Preamp Recommendations?

Hello, I'm a newbie to this forum.  I'm on the hunt for a new tube pre-amp.  I think.  It is replacing an aging PSE Hybrid Line Stage 1 preamp.  Several of the RCA outputs on the PSE don't work, the power button is finicky, and it is all original, ostensibly in need of major overhaul.  Labels on capacitors and other parts have fallen off, etc.  I love the slightly warm (to my ear) holographic sound of the PSE.  I would like to upgrade the SQ.  I find bright, high resolution sound like that of my KEF X300A computer desktop speakers very fatiguing after a short period of time.  

My system consists of an Auralic Aries Mini with SBooster power supply > Kimber Kable PBJ RCA interconnects> PSE HL1 > Kimber Kable Hero RCA interconnect > N.E.W. A-20 amp > Analysis Plus Oval 9 speaker wire > ProAc Response Two S speakers mounted on very beefy steel stands.  I stream a lot of Tidal on the Aires' Lighting DS app.

My short list of possible replacements are AR SP6, AR SP8, CJ PV10 and Quicksilver Full Function.  Two other options are AI Modulus 3A and ModWright LS 100 (if i can find a good deal on one--it's a stretch for my budget), but I'm afraid these two might be too neutral or bright for my ear.  I'd appreciate any recommendations.  Overhauling the PSE preamp is a possibility, but one audio professional i trust told me i can really improve SQ over the PSE.

Thanks for any tips or advice!

Your options will depend on your budget. For warmer sound, most recommend a CJ tube preamp but consider the higher than average gain when matching with your amp/speaker. If you have an amp with a low input voltage sensitivity combined with an efficient/sensitive speaker, you won't be able to move the preamp volume control pass 9 o'clock unless you like your music extremely loud.

If buying only new and your budget is little tight, it would be hard to beat this:

Think about Allnic.  Great sound and great backup service.  I have had the L4000 for six years.  I bought it second hand on the gon.  The batteries leaked in the remote and destroyed it.  Kung Su Park sent me a new one free of charge even though the amp was way out of warranty.

Whats your budget?
Like gdnrbob I also like the 6SN7 pre amps I own a little AE-3 , sadly no longer in production but the Atmasphere is. I don’t know what the price is but it may be affordable new..

I must say your list of possibilities is long is filled with pres that are quite different from each other. The CJ is warm the ARCs are certainly not despite the use of tubes, For instance I own an SP6b. I tried to roll warm tubes into it  but it had no effect whatsoever. Not all tube preamps are warm and not all provide the 3D magic that tubes do in power amps..

Not sure what causes you to think the Modwright LS100 is a bright preamp; far from at least in my listening experience. Drop in some NOS Sylvania , or even Sophia Electric 6SN7s and enjoy
