Audio Research PH6 Phono Stage - How is it?


I know most of Audio Research stuff is top end with little complaints about anything they make. I like tube gear and have more of a preference for the tube sound but looking for a phono stage with little noise. I know the PH8 reference phono stage is a true reference standard but way out of my price range. So that brings me to the PH6, which retails for around $3,500. Not too many reviews on this one and hasn't been compared to other phono stages at a similar price point. There are some good competition at this price, especially the Herron VTPH2, which is also a great phono stage. Does anyone have any information about the PH6?

My current system is Primaluna Dialogue HP Integrated Amp, VPI Prime turntable, Ortofon Quintet Black MC cartridge, Sonus Faber Olympica III speakers. Much appreciation!

I bought a  used PH-7, about $3k.  Noise is a non issue, even with a .28 mv cart like the DV XX2 MKII, although I did feel the dynamics were a bit restrained. It works great with a Cadenza Bronze .4 mv cart, no reservations.  Maybe try it, resell if you need to.
My PH-8 worked very well with the AT OC9 III that has .4mv output. It works even better with the AT ART-9 that has .5mv output. 
One great thing about the Herron and Zesto is their versatility. Unlike most phono amps (ARC included), they have separate MM and MC inputs, with dedicated circuits. If you add a high output cartridge to your system, with the Herron and Zesto you don't have to also get a new amp which won't be overloaded by that output.
I really like the versatility of the Zestos phono-preamp. I am really glad I bought it over the ARC. I can't comment on the Herron because I have never heard it. Though I have heard nothing but good things about it.

You should consider auditioning a K&K Audio Maxed Out. They have a home audition program now.
