I didn't mean that to be a knock against the brands you listed- I'm sure it's nice stuff. Mostly, though, it's just a list of expensive gear I've never heard and was never very interested in. My list would be
different stuff I can't afford and haven't heard.

For starters, probably Bel Canto, Meridian, Spectron, Musical Fidelity & Embla would top my list for electronics, with Lexicon & McCormack also on the short list. For digital source and/or DAC, probably Meridian, Electrocompaniet, & Esoteric Audio. If I had unlimited coin, I wouldn't buy speakers without first checking out the top dogs from VMPS, Selah Audio, GR Research & Epiphany Audio.
Spec-wise, all the manufacturers on your list make gear with suitably SOTA numbers. I'm interested in very hi powered digital amps because of their unique properties. (The Acoustic Reality stuff might merit consideration if Peter didn't come across like such a nut job). At the nosebleed levels of price, it just comes down to your particular fetish, I guess.
Fancy cables? Hell, why not, if it's that or flush the cash down the crapper. I'd probably go in for mid-fancy stuff. I'd buy Boulder Cable's stuff, cryo'ed, with Bybee's on everything, primarily because Wayne is a really good guy: I could live with him making some profit off my "Howard Hughes Factor". And it would keep guys like AV_Phile off my back.
