I have a Magus also so I have a few questions for you to consider before you get another pre-amp.
1) You are using a MC cartridge (I assume - I don't know the Koetsu Black). Have you used resistors to match its output impedance (plug in types)? If not that could be your problem.
2) Have you played with the phono and output stage tubes in the Magus? Perhaps all you need is something warm in the line stage tube - try a cheap new JJ 6dj8 for example, and or some Mullard 12AX7's in the phono stage. That would warm it up in the highs and fill out the bass.
3) Have you optimized VTA on your turntable? That could be also be a cause or solution to your problem.
That Magus is a nice little pre-amp...........:-) BTW, you say you want a dedicated phono stage. What will you use for a pre-amp to drive your amps?
