Their website is up and running:

Doesn't seem to have been updated since the last time I was on the site about 5 or 6 months ago, so I don't know how active the company is, or isn't.
I heard some Soliloquy's bookshelf speakers many years ago connected to a Bryston amp. I went to hear the Bryston. I remember the Soliloquy's as being very clean, maybe a tad bright (bad room accoutics ... glass walled dealer demo room), very strong powerful midrange and surprisingly good/deep bass coming from a bookshelf speaker. Great build quality.
PS: Really good bass from a small twoway bookshelf, I asked what brand of sub was being used.
Would I buy Solioquy for the sound quality? You bet. And the audiophile 'rags seem to glow about the speakers, as well as some of the consumer reviews

But, a limited dealer network and a small company means that my money would usually get spent elsewhere.
