SET sound without a lot of money

Any experience or opinions on the Almarros, Music Ref RM10 mkii, or the Joule Electra Stargate amplifires? Looking for a good SET experience without overly-colored sound or congestion, while pushing enough current to excercise existing 91db speakers at low to moderate volume. I would like to swap one of these occassionally into my system without having to rebuild (re-buy)a whole new system to accomodate a tradional low-watt 2A3, 45, or 300b amp.
