Proprius Mono Block News The latest on the Proprius Mono Block Power Amps. We now have sufficient amounts of metalwork and components to make a start on manufacturing the first production batch. As with all new products it will take time for us to get up to full speed. It already looks like we'll be oversubscribed and there could be "waiting lists" at some point in time - but we'll be doing our level best to deliver quickly. In other words - get your order in early  Here's some photos to be going on with...     ------------- That none should be able to park up and enjoy the view without a smartphone and the knowledge in how to use apps |

That really looks good and I'm sure it will make a lot of people happy. I'm sure there will be much discussion about the capability of such a dimunitive power amplifier, perhaps an indication of the full package with power supply mioght help. One obvious question, what is the cost, having looked back through the threads, have you managed to maintain the anticipated £1250-£1300? And one not so obvious, will it drive my Dynaudio Geminis? an early place on the UK loan programme would be good. |

Great news indeed! How far in development has the Aria come if one may ask?

Just about.
I think you will need to find that out empirically and a word with Jon (FMG) may secure an early loan.
Not very far I'm sorry to say - too many procurement problems getting the Proprius finished has shoved this and other designs on the back-burner for the time being.
Yes, but I've not seen them turn up from our metalworkers yet...  ------------- That none should be able to park up and enjoy the view without a smartphone and the knowledge in how to use apps |

That is fantastic news, indeed! I can't wait to check Proprius in my own system - that's why I still keep Apogee Mini-DAC as a second DAC in my system. This DAC has XLR outputs + volume control, so I can use it for Proprius without any hassle. |

 Because we are trying to sell our house and move upto North Somerset in the near future (I hope!), I will not be placing my order just yet, but I will be placing it I will have to try and get a pair on the loan scheme to torment myself with when they become available! Should I be thinking of modifying my Usher S520s as per your post on the subject? Can't see the wife letting me buy anything better for the time being  Looking forward very much to hearing (or is that not hearing?) this little monoblocks. Will you be making up some cables for these? Regards Les ------------- I don't do mediocrity! Les Sutherland |

Forgive my ignorance but is the Proprius also intended to be used in conjunction with a conventional pre-amp? Most posts I've read only mention DACs or similar. I assume one will be required for each speaker? The input to the Proprius (XLR?) is something I for one have never used. The input will surely make it difficult to use with a pre-amp with phono out, interconnects with phono to XLR required. It will be virtually impossible to use with DIN out because suitable cables will be impossible to source. It's difficult enough obtaining good quality DIN to phono as it is! ------------- Peter P T- LPT/RB300/G1042, Pink Triangle Tarantella/Nima/Ortofon 2M Black, SL1210II, Naim CD5, NAC112, NAP150, Flatcap2, Proac SC1, GS SoloUL,GS Accession , Senn HD250 & HD540. |

oldagetraveller, do not worry. See picture below... 1] Under the speaker sockets there's a boxed caption which says "When used with preamp set vol to max" This means that we expect quite a lot of customers to use them driven from a conventional preamp which has its own volume control, so the Proprius volume controls can be parked "out of circuit" at maximum. 2] Yes, one per speaker. The Proprii serve a number of purposes, one of which is to turn passive (normal) speakers into powered monitors - by bolting a Proprius to the back of each speaker or standing them at the base of each speaker. Therefore they're made as mono amps and two will be required for stereo. 3] Many domestic audio equipment users have never used XLRs, but that's nothing to be afraid of. It's not difficult at all and we'll be launching the necessary cables to coincide with the Proprius going on sale (anytime now). 4] It's not difficult at all to use with any source - preamp or phono out. a] We gave them volume controls to enable their use with a phono stage or other line outs where required.5] I'm compiling answers to a number of questions regarding Proprius usage, which will appear on the Proprius page on our http://www.stereoaudiopoweramplifiers.com/ - Hi-Fi Amp website (shortly to be published), with the kind assistance of morris_minor (Bob Wood). ------------- That none should be able to park up and enjoy the view without a smartphone and the knowledge in how to use apps |

Thanks Graham, you've taken the fuss and PR puff out of high end monoblocks, delivering very high quality and ease of use. I can almost hear the Proprius coming... Jon

Page has some "road works" on it - quite challenging getting all the information and pictures in the right order and places on the page. If tabs look duplicated right now it's because work's in progress. (for others... to get there click Hi-Fi Amps, Mono-Block Power Amp tab, and then the picture/heading link) ------------- That none should be able to park up and enjoy the view without a smartphone and the knowledge in how to use apps |
