Got my set of Proprius amps last week. To start off my listening journey, burning it in with my Esoteric CD player and KEF LS-50 speakers. Everything is digital and sounding fabulous.

Next projects include:
1. Compare the KEF LS-50 bookshelf versus a floor-standing - Magne Planar - see if there is any expansion in soundstage and if it is needed. The KEF bookshelves seem to fill the room adequately...but need to cross off checking the floor standing speakers.

2. Connect my turntable to listen using the Proprius amps with the Accession MC or MM pre amp

3. Connect my Revox PR99 reel player to listen mode

4. Eyeing to purchase the Majestic as the center piece of my music setup.

Has anyone used the proprious with 4 ohm loads?

If so, how did they perform?

Not 4ohm but my Harbeth P3s are rated at 6ohm. Proprius are flawless powering them.

Yes my Magnepans are 4 ohm and low sensitivity. The Proprius amps had no problem and could go much louder than I wanted to listen, without any audible distortion. I hope that helps. Which speakers are you looking at?

I have driven two sub-8 Ohm speaker drivers in parallel from a Proprius monoblock so the resultant impedance is less than 4 Ohms; no audible loss of sound quality. However, I do not turn the Proprius gain dial all the way up (out of circuit), instead using it at 12 o'clock or lower to contribute to the load impedance and also to lower the noise floor.
We do not see things as they are. We see things as we are.

I have a friend who has some KEF reference speakers who is interested in borrowing my propriuses for a couple of weeks and I just wanted to know that they would be ok with a 4 ohm load.

Any comments from Graham?  Min impedance I believe is 3.2 ohm which is pretty low.
