Is anyone using the UA with line out for SILENT (or extremely low) direct recording to hard disk? If so, what else is required (some type of cab sim box, or can you add cab sim AFTER your through your sound card using something like Guitar Rig? I've heard some people use the Palmer DI's, but those can get expensive too, right? How are your results? Is this a viable option / config for getting great tube amp tones thru headphones? How do you guys like the bedroom switch? Is it realistic enough? I'm not really a non-MV guy (but might consider a non-MV amp if the UA is the answer). I actually like good MV amps, but even my MV amp would sound better if I could kick it up a few notches and let it breath and then reign it in with something like the UA. I have tried to be pretty specific in this post so no flaming / hating kicks in... I'm not interested in hearing why MV's are better than the UA, just from people with experience with the UA as listed above.
