Hello Ben,
I had a Pre-1P for a while and thought it did an admirable job. I compared it to the Black cube, the phono section of an AL- M3A, the EAR 834 and the Quicksilver. My take was that it bettered the Black cube and the Audible Illusions by a fair margin, and was on par but not as lush as the EAR or the quicksilver.
My guess is that you would need to spend 2-3 times the cost for a noticable improvement
