Phonostage for Rega P10

0,35 mV.
Regular phono cartridge - cross, neodymium magnet. No compliance figures. I am curious which edge can cut neodymium magnet :)

Looking at the OP's phono stages i think it's better to replace a cartridge to something first class, but not the phono stages

Rega P10 with the Apheta 3 sounds first class to my ears. The Ares sounds great mated with the Rega and I could leave well enough alone. 

I can't help feeling that the Rega would benefit from the next level of phonostage. The NVO looks like a winner except with all those tubes, I'd always feel like there's a bad one in there eventually. I have issues...

Not being able to demo puts me in the forum where enlightened ones can chime in. Budget is $5K after I sell some gear. So that puts me in the following territory.

Allnic 1202
Gold Note PH10
Boulder 508
Herron vtph-2a
Pass Labs XP17
Parasound JC3
Audio Note L3 kit (I love building stuff)

I’m using Gold Note PH-10 with PSU-10 in my system, this phono stage is great if you have a lot of cartridges or at least two tonearms/turntables (like myself), you can connect two MC or two MM at the same time, or MC and MM. It is more flexible for LOMC cartridges with all the loading options and gain options.

If you have just 1 cartridge you don’t need a phono stage like Gold Note in my opinion.

@chakster  I respectfully disagree regarding the PH10. Yes if you only own 1 cartridge now it's still a wonderful piece but us audiofools are always experimenting with things including cartridges so given the PH10's flexibility I think it's a great choice. 
PS: The NVO sonically is still the better choice I for one have never had a tube issue
