I love my Andromeda. I have yet to use it in a recording though.
I was so-so on the Xpander/Matrix-12 sound. yes, that ultimate Roach-machine just didn't cut it for me. It, oddly, sounded awfully digital and buzzy to my ears. That said, I'd like to try it AGAIN. Just to make sure I'm not crazy. My friend, who bought mine, won't sell it back to me even though he doesn't even use it.
I'd love that Eventide H-8000, but my Eclipse does me just fine... as well as my Lexicon PCM-80.
I have a Polymorph. It's interesting. I need to dig into it a bit more.
I have a Waldorf Q (the sexy Nextel Blue color which is, well, pretty sexy) & uQ - the Phoenix is reportedly plagued with bugs, so if you got money for one you might think twice. I don't know first hand about that, but you may be better off with a standard Q.
That new Moog is already being bashed for its $5,000 price tag and still monophonic. I can understand. The truth is the Moog is sort of a one trick pony. What it does, it does well - I have a Model D - but it's not a very good synth for ambient, IMO.
I'd like a Manly Massive Passive and I sure as hell wish I'd gotten in on the new Solaris synth when it was first offered. The initial buyers are getting one heck of a deal - of course it's been 3+ years or something since its initial announcement, but I'd love one of those but not at the current price tag. My friend (the one who doesn't play with the Xpander and will probably barely touch the Solaris) has a custom one coming from the first batch and I think he paid something like $1400. Solaris is way more now for a non-custom one.
I'm sort of interested in a used Dave Smith Prophet 08 and/or PolyEvolver. I traded my desktop Evolver for a Blofeld and quickly sold the Blofeld. The Blofeld sounded and operated great but it was redundant since I have the Q, uQ, and XT.
I sure wish I could drop a load of cash on vintage synths though. Being unemployed and stuff just isn't conducive to boutique synth-buying.
