I don't have a huge amp collection - I simply have my small, medium and OMG riggage* (*Smadder.com copyright 2012, all rights reserved).
Small = SWR Baby Blue II. This little wonder doubles as my ABG rig, my home practice rig, and my Moog Taurus/synthesizer meduim gig rig. The Spectors sound great through it, especially the CRFM w/EMG pre.
Medium = SWR Headlite through a Sonic cab loaded with a single 15" EV driver. This rig doubles as my live Moog Taurus & Synthesizer amp. The spectors sound great through this one as well, especially the Euro w/non-trim TonePump pre.
OMG = Phil Jones M-500 head through Phil Jones 8-T and 16-B cabs. The Spectors sound effing amazing through this one, especially the USA NS-4 w/USA 18-v pre. The punch & low end of this amp blows away any other rig I've ever owned, including my old Ampeg, EBS, Fender, Peavey and Marshall stacks.
The pics below show all three rigs as used at medium & large gigs. The Phil Jones rig handles the bass duties, the SWR Headlite/Sonic rig handles the Moog Taurus, and the SWR Baby Blue II is used as a bass monitor for the drummer.
