Bi amping with Tube and Solid State


I have a Sonic Frontiers SFS-40(High) and Mcintosh MC-2155(Low), wanting to get biamp for my Linn Keilidh. Will I get into tonal unbalance since one is tube and the other is solid state. Any Suggestions?

Don't do it, it's very hard to integrate tubes and SS via bi-amp. Go one way or the other.

You must match the output levels for the amps first otherwise the top or bottom will not sound balanced. Second is to get an active cross-over to be able to adjust the sound. I posted about this a few weeks back but have decided to stick with one amp for now. Too complicated with cables, power cords, room for all this stuff for the amount of time I am listening to music recently. If you can put in the time and expense, this is the way to go.
Fortunately, I have gain control on my McIntosh. According to Jeff, you said go one way or the other, do you mean all tubes or all ss??
Try it - I biamp my Legacy 20/20 Focus with tubes on top and SS on the bottom. Sounds good. If you do not like it than undo.
This is what is known as "Fool's Bi-amping"!! It's bi-amping for the sake of bi-amping. While it is true that you might reap some benefits, the hassles of making sure that high & low are matched is perhaps not worth the time & additional expenditure of cables.
It would be much better to get a very good external xover ckt. This will keep the low freq. out of the high freq path & ensure that the high freq amp is only responding to the signal it really should. This will also keep the speaker cones from mistakenly responding to the low freq. signal, which could cause smearing. Similar argument holds for the low freq amp & the woofer driver.
If you have a volume control on the McIntosh that will help a lot but the tone of the ss & tube amps might be very different. Thus, even if the ss amp gives better bass control you might not like the tone diff.
Just MO, ymmv. fwiw.
