I think that the MBL electronics, if within a price range that's possible, would be the perfect match--the synergism of the product line becomes very obvious at that point.
I've tried the MBL in my home and it's very Gryphon-like in its sound. Not at all hashy or grainy, very smooth, nice staging. Possibly a little 'soft' sounding in the very top. I don't really know if it measures this way, but it sounds to me as if the last octave, (of what is considered human hearing) 10K to 20K is a bit honey colored, and overly smoothed over. This is NOT a deal breaker for me, as I prefer that over the other side of the spectrum.
This kind of overall voicing of the amp/pre and even integrated, may reflect their speakers propensity for a bit of forwardness in it's presentation in that region. So, the process of interactive voicing may be the reason for this result.
If you can find MBL used, (built like a tank by the way) consider that.
Good listening.
