Phono stage for tube system - recommendations?


I recently swapped my Blue Circle driving Merlins for the well regarded Ars Sonum Filharmonia integrated. I have gained a fair amount of air and presence but lost a smidgen of attack especially on higher spectrum of frequency. Front end is a Shelter 901/SME-V/Orbe SE.

I was previously considering moving from my modified GCPH to a tubed photo such as the K&K Maxxed out, Herron,JLTI Artemis, or Aesthetix Rhea, but am now having second thoughts going all tube, and contemplating upgrading along the lines of a Solid State Phono stage instead.

On the solid state side, the candidates are the usual suspects: Pass Xono, ASR, Whest, Tom Evans.

I'm sure at least a handful of members have come to this fork and have some experiences to share. Thoughts welcome!

Thanks,

For SS phono,don't overlook the Aqvox 2CI.It is a sleeper.Great soundstage,timbre and PRAT.I use mine with a tube integrated-simply delightful.
Jmcgrogan2, if what you say is true, then Lloyd has not spent a lot of time working with tubes! The 'unbalance' issue is literally a red herring.
Dan,

Since our get together, I did both the Audio Note tantalum resistor upgrade, as well as a MOSFET upgrade on the CCS...if anyone out there with the K&K still uses the old Supertex part, switching to the IXYS part is a massive upgrade (all for 89 cents from Mouser).

I wouldn't mind another friendly sit-down with your Doshi ;-))

Richard, I can see that happening with the other things going on pretty soon.
Kevin of K&K Audio has a new, fully balanced differential phono stage in beta form. I have one that replaces my original K&K phono pre (by original, it was the first full kit that Kevin sold). In just about every way that you can imagine (sound staging, attack, transparency, flow, pace, weight, color, etc.) it surpasses the current kit, in some ways by a large margin. In the context of a full K&K system (line stage, PP parallel 6550 mono-blocks) it is really pretty awesome. If you think tubes can't get the leading edge of notes right and do attack, you have to hear this set-up. One good thing about dealing with Kevin: he's always trying new things and improving his products, then passing it on. He recently mentioned to me in a phone conversation that dropping the value of the grid-stoppers from 100 ohms to 10 ohms in the phono pre and line stage made the music more dynamic, incisive. I went out and replaced them and his description of the changes was accurate to the T. FWIW, I have used the Shelter 90X. Currently I have a Shelter 9000 mounted and the difference is not trivial.
