I have 2 Cary amps that I use with my Soliloquy 5.3 (special order black ash). I use both a Cary 300sei (11 wats RMS) and a Cary 2A3i (with 4 KR super 2A3 tubes in push pull configuration for 15 watts RMS per side). You will like either... or both! Both of these will cost you a little more that $1500 each, but...you will not need a preamp or interconnects. I suspect you could find either of them used for $1700-$2000...but not mine! There is nothing wrong with the SF or CJ... or a lot of other good tube amps, but the owner of Cary founded Soliloquy and I believe the 5.3's and the rest of the Soliloquy line are still voiced with Cary amps. Both amps will drive the 5.3's to sufficient volume levels. I have never had the volume control on either past the 11 o'clock position. The 300sei, as might be expected, presents a more lush midrange and sweeter highs and slightly better imaging that the 2A3i. The 2A3i has a fuller and better balanced low end without giving up much on the mids and highs....sounds kinda like a SET amp with balls. I do switch the amps off every week or so and when one is on the Soliloquys, the other is with B&W CDM SE's and a sub. I do not use a sub with the Soliloquys normally.
