Graham,
Any news on the release date of the Proprius? Am I right in thinking that input is via a balanced jack? 'Scuse my total ignorance of this, but I assume this is a quarter inch "stereo" jack? How would you connect the unbalanced output of a pre-amp to it? Would it simply be a question of getting a phono to XLR adaptor, and then using an XLR to jack balanced cable? Lastly, such a setup could also take the output of a DAC or unbalanced phono amp directly, using the Proprius' volume control - presumably? Thanks!

Single or Mono format would be more convenient for a multichannel setup, which would be a nice setup for me. Will the configuration still be "dual mono" if combined into a single chassis? Tom |

The Proprius' are awesome. I tried them with different bookshelf speakers and some small floorstanders, and they perform well. For a pair of amps of this size, they are an audiophile miracle.

I'm saving up to hopefully be able to get an Aria and a pair of Proprius blocks all in one when the Aria is finally completed and put on the market. Presuming they'll come in a bundle as they're natural complements to each other.
Although I'm also tempted at maybe getting a real quality piece turntable first. I saw a vintage one from Acoustic Research, with an SME 3009 fitted, for sale that at least looked the business. But I have no idea of how good it sounds. Anyone have any experience with vintage AR turntables? Edited by suede - 19 May 2013 at 3:32pm |

Hope this is the right place to post this. I am not technical and have a query about the Proprius. It uses a switch-mode power supply and, having had a pair of amps on loan, I can confirm that the power packs are extremely well-made and that the sound of the amps is simply stunning. However, I was wondering about the decision to use a switch-mode supply. On other forums, these supply often get a bad press and, especially with Class T and D amps, there is a view that a replacement 'stiff' linear supply greatly improves the sound. I understand that an internal power supply would make the Proprius too big and costly but would there be an improvement in sound quality/performance if an external linear supply replaced the switch-mode units?
This query is raised for my own personal interest as someone who has no technical knowledge and is in no means a criticism of the Proprius - I'm saving up to buy a pair!!

The Proprius sound fantastic with the switched mode power supply.
One of the things why we probably have switched mode power supplies is probably the development cost and testing of a linear power supply, and the switched mode works just fine! |
