I picked up the PCA-2/HCPS and HCA-2 when PS Audio discontinued them a few years back, later I added a MF X10v3 tube buffer in the loop. My speakers are 25 yr. old Vandersteen 2C. I also added AirMatrix XLR's and Silver Resolution [better!] IC's. Last fall I purchased a AE-25 Superamp on Audiogon. The results were way better than I hoped for. When I rolled 6CG7 RCA cleartops and 7DJ8[Haltron label] tubes everything came together. I stopped hearing the hardware. Now to the point. In my system, the PCA-2/HCPS and Vandersteen 2C[12ga hookup wire from RS] allowed each improvement to be heard. Would the Pass be better? Don't know. But I think the PCA-2/HCPS is a fine preamp[phono card included]. For now I, still have my HCA-2 but no way am I getting rid of the PCA-2/HCPS AE-25 combo. I suggest that you live with what you have until you can pin down the strength and weakness of your system. Work in the direction you want to go by optimizing the necessities. Be patient, try not to get obsessive, wait for good opportunities and enjoy the music. That green grass over there takes yardwork.
