I'm in a different camp than most of the folks that posted here (and I'll likely get blasted for it). I would encourage wavendon to explore some reconditioned vintage tube or solid state integrated amps or receivers. If you can find something with variable loudness controls, that can make a very big difference listening at low volumes. I believe the lower powered solid state gear from the late 60's and early 70's has a very nice tone and sound quality, and the tube gear from the 60's sounds absolutely wonderful. Both of these should be a decent match for your speakers. My current favorites (in no particular order) from extended listening periods with moderately efficient speakers are:
Sansui 777a
Marantz 2215
Marantz 1060
Luxman R1070
Harmon Kardon 330c (the 330b might be even better)
McIntosh MA6200
Fisher X-202-B
Scott 222B
Most of these can be purchased in recapped/serviced condition ready to play for many more years for less than $1000, and some way less than $1000. Good luck on your journey. Feel free to PM me if you want more details on any of the pieces I mentioned. I've spent many many hours with all these and know them well.
