hi jack,
here's a response w/a bit more specifics... ;~) if ya liked the thiel .5's but they didn't *jam* enough for ya, for ~$1500, if you're patient, you'll find a used pair of 3.6's. these are full-range, plenty of detail, & they will disappear as well as any monitor. while jim thiel is known to come out w/a new model every now-n-then, there's a reason this particular model hasn't been changed in, what, ten years, at its price point...
i also recommend picking up a used tube preamp down the road. (i'm partial to melos, there's several f/s on a-gon at present.)
for amazing digital on the cheap, pick up an art di/o dac from boldercables.com for ~$120, have it sent directly to wayne @ boldercables for mods that run ~$265. then add a $4 upgrade power-supply from hosfelt.com, & pick up a couple $300-$600 isolation transformers on ebay for ~$25-$50 each - one for the transport, one for the dac. absolutely amazing performance, considering its price. amazing performance *period*, imo, even *not* considering its ridiculously low price. if you're handy w/a soldering iron, you can buy all the parts needed for ~$100, & diy, instead of sending it to boldercables.com.
you will have a system that does *not* hide the truth of the recording, yet it will still be eminently musical...
oh, and, re: subwoofers, for possible future consideration: even the thiel 3.6's, full-range tho they are, will benefit from a quality subwoofer system, imo - outboard electronic x-over, outboard amps, and a *pair* of quality passive subs. my old thiel 3.5 certainly did, & they go even a few hz lower than the better-in-every-other-respect 3.6's...
regards,
