I've not heard the Plasma tweeter, but spent a lot of time at 2012 RMAF listening to Jim's then flagship speaker. As I was considering downsizing from 400 lb Monoblocks and Soundlab speakers, to hand held amps and Jim's highly efficient speakers, the Vaughn's were sonically very appealing!
I ultimately choose to upgrade & stick with Soundlabs, but if I didn't, Vaughn's would have been on my very short list. BTW, I bought my original Soundlabs from Jim.
Furthermore, I more than agree with the previous poster's comments regarding Jim! He formerly was a brick and mortar audio store owner in my part of the country. There, I got to known him quite well and learned more about this hobby from him than from anyone else, or anywhere else. First and foremost he was a consummate hobbiest, rather than a salesman for sales sake! He thrived on quality playback and had an uncanny knack for getting the best out of equipment and rooms. Over considerable time and with numerous instances, I came to trust and value his opinions. I found his opinions as unbiased as any one of us ever can be. And no, I'm not related to, nor connected to Jim in any way! He's simply one of the good guys in this hobby and although it has been several years since he left the Midwest for CA, I still miss him and his store!
