No worries. I have been pleasantly surprised with how quiet the Proprius are with my 300 Ohm headphones. I guess it's a sensitivity v.s impedance thing?? The Proprius would likely be unsuitable for driving high sensitivity / low impedance headphones but I'm not the expert here; Graham is. I wonder if he has tried his HD250II from Proprius...
With my 300 Ohm Senns, the Solo ULDE seems to offer no sonic advantage over the Proprius. Doesn't seem to be any more or less resolving; the monoblocks just have more power available for driving speakers which is why I shouldn't part with them... Edited by Ash - 26 Sep 2014 at 8:52pm |

The specs show the Proprius amps drive 4 ohms as well as 8, and they have no trouble putting more current through the lower impedance points in any of my speakers. They sound great at any volume short of madness. I expected that but it's remarkable that they can drive 300 ohm headphones just as well as 4 or 8 ohm loudspeakers.

I have just plugged an old pair of KEF Coda 9 floor standing speakers in, and they sound awesome on the end of the Proprius amps. New they cost me £299 and that was more years ago than I care to remember.
Mtprs H will flip if she sees big black boxes, so they will have to go back to home cinema duties soon. |

I have just added the final piece (apart from the linear PSU I have just ordered)of my amplification. A nice "Class A" preamp. Yes, I was too impatient to wait for the Aria(?) and I didn't have the funds for a Majestic. I understand that Graham is a busy man, and you can't do everything you want to. When the Aria gets finished, I certainly intend to have a listen to one. It should be a partnership made in heaven.
The difference between my system now that the new preamp is in place and the Proprius being fed by my Arcam Alpha 8R is staggering. The speakers are probably the thing holding my system back now, but I have a bathroom to refurbish before Mrs H will let me entertain changing my speakers. I can certainly recommend the Proprius amps. |

Great news! But I have some bad news (for your wallet) to go along with it. I, too, ran my Proprius from an Arcam, the Alpha 9. And yes, what a difference from the Arcam in its own! But now I have a Majestic. Sorry, you'll really, really, really want to sell family members to get one!

My cash priorities will be turning to my family members for a while!
I have indulged enough for a while. There just are not enough analogue inputs on a Majestic for me. I'm a bit old fashioned, and I still use a tuner for when I just want some background music. |

Can anyone tell me what difference it makes bi–amping the Proprius? Is there any advantage to having 4 amplifiers instead of 2? I have already discovered that in my system we preferred the sound of a single speaker cable rather than bi-wiring.
