Like others I am not familar with all of the amps in your list, however I have very revealing speakers with a nominal impedence of 5 ohm and 86dba and I use a Muse 100 as my summer amp in leiu of 160wt tube monoblocks. Except for some loss of upper frequency air and extension I find it more than adequate, in fact it is the only reasonably priced SS amp I have enjoyed in my current system. The 160 Muse is an improvement over the 100 and at its typical used price I would give it strong recommendation for consideration.
