Ok, here's my final impressions on the PH-10. I have about 20 hours of listening to the phono preamp with the Classic Evo TT with a Nagaoka MP-200 that I recently replaced the stylus on so it is still breaking in as it takes about 30 hours per Nagaoka and they are spot on with the break in.
I am loving the phono pre. I fixed the shoutiness that occured on high dynamic range albums. The preamp allows you to adjust the gain up or down in 3db increments for a total of +/-6db. I turned down the gain and switched from XLR to single ended and that fixed the problem entirely. This preamp is really made for MC cartridges as there are multiple settings for them but only 1 setting for MM cartridges. The problem with MM carts is that you can only turn the gain down to -3db. With MC carts you can do +/- 6db. That is why I went from XLR to single ended to lose about 6 more db in gain and it worked like a charm. I will go back to XLR cables when I upgrade to a MC cartridge next fall.
There already is a bit more warmth with the Nagaoka breaking in and the sound becoming more detailed but smoother at the same time if that makes sense. The bright edge has disappeared. The sound stage is tremendous and there is a lot of depth to the music. Micro details come through in spades. The midrange is full and lush without sacrificing transparency and air. Bass is punchy and not lacking in the least. Treble is smooth and airy and sibilance is contained with occasional break through on some recordings.
Some music sounds better than digital depending upon the recording and my digital end sounds great with my Luxman DAC and WW Platinum usb cable and JCat usb card. All my LP's that are from Acoustic Sounds and on 180gm to 200gm vinyl sounds superb and better than digital IMHO. No fatigue whatsoever.
That said, I would still like a little more warmth as I am so sensitive to brightness. I will do another review come November when I upgrade the cartridge to the Shelter 501 v3 MC cartridge. So for now it is a keeper and it may be the last phono pre that I ever own, it is that good unless I win a large amount in the lottery. Then, I will give it all away and build a system from scratch with an unlimited budget

Something like the Boulder system at RMAF a few years ago. My son and I still talk about that room.
