Just noticed that the new redesigned RM15 PIU is now available from Torus. I understand that it has some design changes that make it more efficient and slightly smaller. Biggest change is the pretty impressive drop in the price: it went from ~$2800 to $2000. I've posted the write-up from the Torus website (only documentation available that I can find) below:

Latest news from Torus Power
Torus Power RM15 (top right) has been re-engineered into a more compact size, and lower price ($2000 MRSP). Torus Power RM15 delivers the maximum power available from a standard 120VAC outlet, and delivers all the Torus benefits of cleaner power, total isolation from the power grid, more dynamic range and detail in audio, enhanced video, plus complete protection from lighting, spikes, surges. The consumer style 17" face-plate is available in silver or black. Rack mount versions are also available.
I believe that a post by Mr. J Tanner 8 months ago informed us of the new product. I will dig it out and post the link here again for your reference.
Needless to say, I no longer had any arguments against ordering one. It's on its way but 30 days away (new orders slowing processing as I understand it).
Thank you both Torus and Bryston.
