Dear all.
Whilst I'm saving for a phono stage I am planning ahead for future purchases and how to incorporate them into the home in a family-friendly fashion. Specifically I am thinking of the location of Proprius power amps in relation to the pre-amp and speakers. Is it generally considered better to locate the Proprius next to, or close to, the speakers, with the attendant short speaker cable run and longer interconnects between the pre and power amps? Alternatively would it be more sensible to have the pre and power amps close to each other and have a longer speaker cable run? In case it is relevant, the distance between the pre-amp and the speakers will be two metres to one speaker and four to five metres to the second speaker. (The pre-amp will be located in a corner of the room and the speakers more or less central to the seating position.) No mains cables will be in the area between the pre-amp and speakers. Thank you.

The Proprius on the speakers is only viable where a balanced feed is available from the preamp/control amp.
In my own set-up I use long speaker cables, even though I have the balanced output of my Majestic available. I run unbalanced interconnects from my Majestic - which acts as my preamp - to the Proprius inputs. |

I think Graham is right. I have my Proprius amps next to each of my speakers (I lifted them off the carpet on small platforms) and use long balanced feed from the Majestic with very short speaker cables. It sounds great to me and may be the best fit for your domestic situation, unless I have misunderstood. |

I'm interested in the experience of other proprius users who have moved their amps closer to their speakers. What changes did you experience in sound quality as a result?

I tried both, and found very little difference (if any) in sound quality, but I was using a maximum length of about 3m.

For connecting Majestic to Proprius, I was led to believe that Lautus-R3 1.5m is probably the optimum interconnect. It is the minimum length required for the EMI-suppressive ferrites and uses the anti-phase signal only (unbalanced) rather than either the standard phase or both phases together (balanced). The anti-phase (R3) alone does not carry forward common mode distortion whereas the other two options do. So in theory, it seems this interconnect would provide the purest output. The benefits of using anti-phase plus ferrites should offset the surplus length of 1.5m.
CuSat50-R3 of any length uses the anti-phase but has no ferrites. Libran of any length uses both phases (so carries forward common mode distortion) and also has no ferrites. So even ultra-short lengths of either of these interconnects is unlikely to offset no ferrite EMI-suppression and carrying forward common mode distortion on the standard phase of the Libran. Whether you could actually hear a difference in purity between the cable choices in another matter entirely. You'd need to optimise the rest of the system before being able to hear any difference at all probably.

I have the Proprius amps close enough to use Spatia jumper leads about 150mm long because the Magnepan terminals are at floor level. Before that 300mm bi-wire cable which replaced 4,000mm bi-wire cable from hifi rack to speakers. All very good, subtly different in sound.
