Having read all I can find on tube friendly, damping factor etc, I have the following questions:

If a tube amp has sufficiently low out put impedance (and the resulting high damping factor), I could still be all right with just a couple of watts? It seems that the low damping factor in SETs is the real problem and not necessarily the low power output? After all, if the speaker has 100db/1w/m, 2-4 Watts should be enough, yes?

In for example a PSE arrangement where the additional tube is used for lowering output impedance instead of doubling the power could do the trick??? Example: using 2 x 6as7 (one tube envelope) with for arguments sake a 5kohm primary would yield high enough damping factor to allow for higher Zmax on the woofer...????

Sorry if the quesiton is foolish, but I am really curious on this:)
