Had my Proprius amps and Majestic since 2015. The Proprius amps are mounted directly on the back of my speakers (Frugal Horn XLs), this made a nice improvement.

I’ve had no desire to upgrade any of the amplification (inc. the Accession MM from 2017) or cables (Libran and Lautus). The sound is so sweet no matter what I’m playing.

I put an Enigma on the Majestic and I’m thinking of doing the same with the Accession.

For what it's worth, my pair of Proprius is piggy back to a early 1990's BW 620 much tweaked 8inch cone with a bass radiator inside a 30 litre Volume box and very balanced in musicality, and loud enough to fill a 3.5 metre by 5.5 metre lounge sitting room. Acoustic music recordings of late 70's to 90's mellow and sweet tone and is there to stay until I can no longer feel the sheer music to enrich my soul .....But Electronic Pre-amp on my DAC output 2.7 V is the weak link. Yes, libran interconnect from Proprius to the 30 litre Speaker saves for expense Speaker cable and the beauty of two mono amps to create the sound stage is super value.

Thank you for your positive appraisal. I will not be able to add suggested "whistles and bells" since I have recently retired, and now it's up to John C as to which direction things go.

The Proprius paved the way to a better understanding of how a.c.-coupled power amplifiers work best - at least to my understanding. As is usual, the technical subtleties are not easily described. I intend to continue sharing the knowledge on the "7eventies indulgence."

Hi Shashi, GS equipment should come with a health warning, it's adictive!  The Majestic compliments Proprius and Accession to make a wonderful music reproduction.  Happy listening.

I have now crossed the 50 hour playback mark with my Proprius mono amps. I have connected my Esoteric DV50 CD player as source and the KEF LS50 bookshelves as speakers

The amps have already disappeared into the background - and so have the KEFs. Its just music and sounds wafting around the room with no equipment drawing attention to itself. I might as well store the Proprius inside the sideboard.

The sound is absolutely as it should be - not overtly digital/loud, the acoustic instruments have the warmth and depth. There is ambience - as in it feels like sitting in a recording room/small performance hall. The volume scales up and down smoothly across all the equipment - no jarring or harsh sounds - except loudness. For a change, I am turning the volume lower since it does not take much to fill up the room.

So I guess my concerns of obtaining enough volume from Proprius are at rest. Of course I would experiment with a floorstanding speaker in the future - especially the Magnepan LRS speakers.

I have not yet played anything analogue - reel tape player and vinyl is next on cards.

And after waiting, reading, reviewing and comparing, I have pulled the trigger on the Majestic. I cannot wait for the Majestic to drive the volume on the Proprius. I have also ordered all those cables including Libran, Spatial, Lataus USB...which means more comparison and satisfaction on the cards.

The only downside, given the size/shape and high gloss of the KEF speakers, I will not be installing the Proprius on the speakers. But the reduction in cable clutter is totally amazing. I will be able to get away with just speakers on top of the entertainment center...nothing to see here.

Goes back to my original nit with Graham - he needs to make his equipment huge and flashy with those big truck grills, dazzling LED lights, a smoke generator, maybe a bubble maker, some additional weight of copper wound transformers, dials and lots of labels of audio standards. That stuff sells!!

Meanwhile I am happy with my selection of solid state silver boxes that give me the perfect acoustic instrument playback...do not miss any tubes and bells and whistles. My product collection now includes: the Revelation C, Accession MM, Accession MC, Proprius, Majestic (soon), Enigma, Lataus, Cusat, Spatial,
