Cwazz - Assuming your Fisher can get you about $400 back in your pocket, allow me to suggest the following amps that are all on Audiogon now - most I have heard minus the Cayin (but I've heard great things about them). All of these should be fairly easy to resell also.
Vincent SP-331 Hybrid (although $700)
Cayin TA-30 Bizzy Bee (this would be my choice)
Jolida JD-302B or 202A
Rega Mira 3 - if you want solid state
I believe any one of these could be a great match for the Lores. It seems like you prefer vintage for front end, no?
