So I spent a bit of time yesterday with PrimaLuna EVO400 preamp and although decent, it just didn't add anything tangible. Maybe a bit of warmth, but the amps felt anemic with it. Not a good match. Also tested the EVO 400 amp with it and that doesn't agree with the AP Avanti III. They sounded glorious on my friends AP Virgo II's.
I'm guessing that I just need to try a few different pre's to get an idea of what works...
