Rogue Audio Perseus Preamp Vs. Magnum 99

Has anyone listened to the Perseus and the Magnum 99 preamps on a one on one test. If so, what would you say the audiable differences were, if any?
I have owned them both, although not at the same time. Overall I prefer the Perseus, but I did have it upgraded by Mark O'Brien with about $500 of internal goodies.

In my system, the Perseus is more neutral, much more transparent and dynamic. The 99 seemed to have a mid-range tube glare that I could never get rid of even with various NOS tubes.

Send me an email if you want more detailed information.


Thanks, I will send you an email tomorrow.
