Just a note of caution: please make certain all of this is properly gain-staged and be conservative on the level settings to avoid clipping anywhere in the chain for both outputs. I might add that at least two inputs with individual loading adjustments would be great. How to deal with stereo is also a question. I have not looked at the KAB, but I thought it was a mono device. One needs balance between the two stereo inputs before summing at least. If you're designing something new, a full-stereo RIAA option would also be great. The raw output should not be summed. It should be stereo. In cassette work, I sometimes go back to the channel-selection stage to improve a segment when dealing with mono tapes. Cheers, Richard -- Richard L.
