Hi Teeshot, I have the XP15 with the XX2mk2 on my VPI Classic 1 and it's a great combination. I have found you need a lot of gain with this cartridge. I run the XP15 at 66 db gain loaded at 100 ohms into my Pass XP10 pre which provides another 10 db gain. The XP15 does everything very well, esp the midrange, and bass control is astounding. It's completely smooth and grain free. Very flexible in terms of loading and gain, but the tiny switches on the back are a bit of a pain to dial in. When everything is set up properly, excellent recordings sound fully three dimensional, wide and deep. Poor recordings can't hide but they can be bearable with the XP. I listen to a lot of rock and jazz and it does those genres great, but everything sounds great on this phono pre. You can work with Mark at RenoHiFi and get a great deal and a 2 week trial. I have not heard the Herron or the Avid but considered those brands while shopping for mine. Good luck and keep us posted.
