Mnmatt - I'd be very interested in how you're set up with the jukebox changers - who writes the Titletrack software and does it physically interact with the changers?
I have two Sony CD changers and have it set up to control them with the Nirvis Slinke controller from my PC. The controller costs $$$ and they give you the jukebox software. Conceptually it works great - fabulously flexible keyword assignments and infinite flexibility for playlists, etc. In reality, the jukebox software is the most bug-ridden software I've ever allowed to crash my computer more than once. I've tried to coax it to behave because I want the functionality in the worst way, but it's a bad piece of software and I've probably now given up. I'd love to know some alternatives, especially if somebody has some success stories.
The other cool box I've seen is from a company called Lansonic. It's a hard-disk based "jukebox" with an ethernet interface on the input side, hard drives for storage in the unit, and an audio-component output side. It connects to a network and looks just like an NT server to other computers on the network. You can control it from any browser on the network, and it can play songs from any location on the network. I'd go for it in an instant if I was convinced it actually worked reliably, but it's a relatively new product and, like Nirvis, is probably a hardware company that writes the accompanying software "because they have to" and many companies like this produce bad software.
I love the best possible reproduction path when I'm sitting to specifically listen, but the technology exists in spades to have your whole music collection at instant access, and that's what I want. Unfortunately, I haven't been too successful coming up with the right mix to accomplish this (and, I agree - the Escient stuff is just too expensive even if it works flawlessly). -Kirk
