Phonostage for Rega P10

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

My understanding regarding the Rega is that its performance is so good, a top shelf phono preamp would serve it well

Are you looking for a phono stage for the actual cartridge or for a turntable for some reason ? Would you like to mention your cartridge specs and type?  

Then you’d better post Apheta 3 specs, i can’t see even the Output of that cartridge on their site, anyone can comment ???  350μV is 0.35 or what ?

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.

For one cartridge JLTi mk4 or mk5 is much better phono stage than Gold Note PH-10 which is not cheap at all with PSU-10 (power supply). If the budget is not the issue then unused 2nd input on PH-10 (and digital interface) is what you extra pay for.

JLTi Phono stage with one input with gain switch and optional RCA plug load resistors will cost less ($890 / AU$1490)), but the sound is even better. No limits with RCA plug load resistors for LOMC (better than Gold Note). The JLTi can be modified by the manufacturer and after this mod MM cartridge can be unloaded (100k Ohm instead of 47kOhm), you can't do that with Gold Note.
