Thanks for the feedback Alan. I realize that this upgrade came of came out of left field and is not inexpensive. Retail price for the PS upgrade, for existing LS 36.5 owners is $3995, through your local dealer. The cost for a LS 36.5 w/PS 36.5 when purchased new as a set, is $8750.
This started out as a curiosity on my part, as to how good an outboard, dual-mono power supply could sound and what it could do for the already exceptional 36.5. I found the bass impact, separation, resolution and overall physical body of the musical presentation to be staggering. We then took it one step further, by adding discrete tube-voltage regulation stages, using the 6EA7/6GM7 tubes. The PS has a total of four transformers, two chokes and four tubes. It weighs more than the stock LS 36.5 and is finished in the same chassis/casework to match the LS 36.5. As a result, it is not cheap to build.
It wasn't a planned upgrade, but it was SO good, that we decided to take it to the RMAF show in Denver and a feel for people's reactions to the sound. The show was a huge success, the sound was phenomenal and our LS 36.5 w/PS 36.5 made beautiful music with Art Audio Vivo KR 300B P-P amp. We decided that it was an exceptional upgrade and therefore would be available as part of our lineup.
Our first production run was small, and is already sold and spoken for, before they are even built. The next production run will be bigger. Obviously this is a Reference piece for us and is at a higher price-point that people are accustomed to seeing from ModWright. I will also say, in 100% good conscience, that it STILL represents the same level of performance/value that all of our gear does.
