Neh, t'badlands! (Lancashire)
Another Neh. They make them do nearly full output at around 1 o'clock to sound impressive! Been there - didn't like it - resigned. |

Hi, pictures in new website great and notice the Proprius has a different power supply to the normal psu. Is it a different case or differing supply?

Yes, it's a 48 volt bought-in switched-mode with built-in short circuit protection and excellent regulation. Does 120 (real) watts.

These little gems need no tweaking whatsoever.
They are driving my 6Ohm Harbeths with ease and then some srtrapped to the back with super sticky velcro. It's just amazing how quality sound travels at normal listening levels.
It's fair to say everything else sounds poor to middling by comparison. |

Hi all - a question for those with more technical knowledge than the likes of myself!
My Majestic-Proprius combo happily drives my Spendor standmounts in a small-medium size room, so much so that I rarely exceed 9 o'clock on the Majestic's volume dial when the Proprius pots are set to max. If I adjust down the Proprius to say 12 o'clock, the Majestic can go to 10 o'clock or beyond with comfortable listening levels. BUT the sound changes - it's more relaxed, slightly less dynamic etc. Ohms Law tells me that turning down the volume on either one, or both, components will reduce the Power (W) output to the speakers. So why the variation in sound?

My setting is to have the Proprius level at about 2 o'clock. It reduces the gentle hiss but most importantly means I can use the more of the Majestic volume control range as you mentioned.

The Proprius exhibit audible hiss at high dial positions with low impedance loads like speakers. I don't set them at max or out of circuit for this reason. I set the Proprius between 9 and 12 o'clock, allowing for more usable dial range on the Majestic too. For my cardboard open baffle speakers where I listen at close proximity, I set the Proprius at 9-10 o'clock to achieve a totally silent background at the speaker cone so I can use them like enormous headphones with angled drivers. Set at an appropriate signal to noise ratio, the Proprius are just like the Solo Ultra Linear.
I guess in theory that you are better having a higher preamp level going into a less amplified amp stage; a purer output in terms of signal to noise ratio. Edited by Ash - 05 Jul 2022 at 7:37pm |
