Some general feedback from a very recent buyer (for whatever it is worth):
I spent about 30 minutes looking at this product and skimming though this thread before pulling the trigger. I saw that it was tied to Bill and figured if I was going to buy *another* measurement system, it would be nice to support Bill in some very small way. My existing meaurement systems can be a bit buggy since they rely upon external sound cards and mic preamps to work with laptops... with mixed results at time thanks to older drivers, aging equipment, etc......and it was a bit clunky carrying it all around to customer's houses and having to plug it all up.... and then sometimes having issues with drivers and getting things recognized while you're trying to look semi-professional in front of the customer... this seemed like an easy plug and play setup with little fuss. I paid my money and bought the unit in December.
I'll be honest, I bought it incorrectly assuming that the surround capability was coming as an upgrade not far down the road. That's entirely my fault for not reading more closely and fully understanding that I'd have to pay more for the DVD... I *assumed* it was going to be a download, like a version upgrade and folks could burn their own discs.
So what did i get for my modestly discounted from full $399 MSRP purchase price?
As far as I can tell, a $60 microphone (unless there is some dramatic difference between the mic included with the kit and the UMM-6 that PE sells separately), and the rest covered the person to do the calibration on said microphone and the actual OmniMic software itself.
The software is fairly clean and relatively straight forward to use. Not world class, but not bad at all compared to some software I've used in the past. Not quite as much of a learning curve as REW and slightly easier interface, I guess, to use. It's not buggy and has good help files. I've personally not used anything in the software that I couldn't already do with REW and/or HolmImpulse for free. I thought I was going to be able to use it with theater setups and tuning those without having to swap RCAs around (for pre/pro and amp combos) or swap speaker wires (if using a receiver based system). But it appears I have to pay more for that capability.
Honestly, if I'd known the DVD was going to be an additional expense before my 45 day window was up, I likely would have taken advantage of PE's generous return policy...... having to pay even more for the DVD is rubbing me the wrong way no matter how much I'd like to support Bill in some small way. As it stands, even if the DVD were included, I'm not really seeing the value for dollar over buying a better USB mic than my current mess of stuff and using the other free software options. It pains me to say it, too. The extra charge for the DVD is the little extra kick in the teeth that is leaving a bad taste......
IMHO, YMMV, blah blah blah, etc. etc. etc.
