Ohm Walsh Micro Talls: who's actually heard 'em?

Rebbe,

YEs, the Peach is the one without phono and apparently lower possible output impedance also, so that would be the Juicy Music one for you to consider.

Tvad,

I know you've heard a lot of combos and have a good handle on the matching impedance issue between amp and pre.

Do you find that the ratio of amp input to pre-amp output impedance is a reliable indicator of performance? If so, what differences do you hear consistently as this varies? Are there thresholds regarding this ration that can be identified that reliably predict actual performance in certain areas?

Thanks for whatever insight you might offer up on this topic.

Tvad,

Have you found the better clarity and control extends into the upper frequency ranges as well?

Any downsides that you can identify to go along with the benefits?

This is something I'd really like to test out in my system.
