linelevel pre that facilitates balanced bi-amping?

You can add the Aesthetix Callisto to the SF Line 2/3. Actually had an SF 3SE home for extended audition. The Callisto was the only linestage I found that beat it out overall. It was a close thing. If remote had been a big deal the decision might have swung the other way. Both pretty much smoked the ARC LS2B that the Callisto ultimately replaced.

Thank you everyone for your thoughtfull replies. Interestingly enough my friend previously owned a Sonic Frontiers Line 3. He sold all his equipment prior to a recent move. His requirements have made a rather radical change with the purchase of a TacT 2.2.

So far I have found one that meets all the criteria, the GamuT.

can someone provide a list of all pre amps ss and tube models that have a biamp capability ..i wish to see what my choices are..thanks

I am not sure but Gryphon may have such a pre-amp.
