From the review by Mr London -
An audiophile who will spend $3,000 on a dedicated CD transport would be very motivated to spend a bit more to get the maximum performance out of the Box RS2 transport.
.....I contacted Mark Schneider, owner of one of my favorite companies, Linear Tube Audio,......They also make very high-quality linear power supplies that can be customized for other companies’ gear. I had Mark take their LPS+ linear power supply and change it from a 12V/3Amp to a 20V/3Amp to match the Box RS2 transport input level, along with building a DC umbilical cable. Total cost, $645.
This for a custom made external LPS. In my experience custom made are much more expensive (and not just in $ terms - yours and my time to research and talk and research, perhaps travel, etc. It adds up) than a supplied component due to one off tooling costs and so on.
And after all that, it is still external. I maintain that it is false economy to not include an internal LPS. Like saving pennies on an heirloom.
Still, well within comfort boundaries compared with the prices of other technologically comparable units - those prices are so far away as to make any comparison like apples to oranges.
The Pro-Ject engineers would design one that is optimal for the transport. I would suggest that this would be "better" than a generic one that is designed to fit around the product rather than specifically for it.
So, we agree -
The cherry on top is one can further extend the sound quality if they decide at some point to add a LPS. This is a splendid scenario as far as I am concerned.
