Funny. I recently switched from my Conrad Johnson pv-11 to my krell Pam 5 and the krell has way more detail. I even had nos telefunken 12au7’s in the cj. I think I’ll be staying with the krell for a while. Maybe look into buying a nice Ayre pre. I believe I’m hearing a lack of distortion. The krell also has a separate power supply and is a very quiet pre.
