Mixing SS and Tubes

Please explain your first statement. I agree with your second statement, but suspect I do not with your first.

Tbg, I'm not sure if your question was addressed to me or not. Many speakers have impedance loads or power requirements that are challenging to many tube amplifiers. I agree with you that the impedance matching of tubes to solid state can be an issue, but there are some fairly low out put impedance tube pre-amps (Sonic Frontiers Line 3, etc.) and some fairly high input impedance solid state amps (Electrocompaniet, McCormack, C-J, etc.) to work with.

Yes, I was responding to your comment about "speakers will have a lot to do with your ultimate success." It is certainly true that some very low impedance speakers could cause problems for tube amps and for ss if there is a thermo runaway possibility.

I think the old wisdom that you could not have tube preamps run ss amps is out of date. I suspect the old wisdom to the effect that some "tubes" in the mix will help your sound.

Unsound what should be the ratio of impeadance when dealing with tube pre ss amp issues? I currently have this setup(see my response above) and in addition will check my manuals on both pieces. Thanks.

I vaguely remember a 1 to 4 ratio, but the smaller the output impedance is relative to the input impedance of the amp the better.
