Your current setup is about where I'd like to end up truthfully (with the exception of the uber-dac). For me, a better DAC and probably a future headphone upgrade are still on the table. I'm finding the WA7+WA7tp to be quite satisfying at the moment. I'll probably wait a year or two on the headphones, as the current version of the LCD-2 with the fazor is actually very, very good...not to mention that I'm always interested in checking out whatever new and improved products are on the horizon. A proper Stax setup is beyond my reach, though I'd like to listen to one at some point just to get a taste of what the SR-009 sounds like.
All this said, there's a lot to be said for a setup that makes you "perfectly happy". Recognizing this is probably as important as anything, truth be told.
Haha. Right. It's all those
other engineers who are hacks/idiots. I'm not sure why they can't get things right.
