Keith (or cheekyboy as he is known in these parts) has kindly sent me a Majestic preamp and 2 Proprius monoblocks as part of the Graham Slee loaner program. Loaner programs are great, as I'm discovering, you get to play with new toys for a few weeks for only the cost of the postage (both ways guys, best to get that out there now, both ways) and that is a no brain-er in my opinion. I haven't had the Slee gear for long enough to do a full write up yet I just thought I'd start on the process ahead of time and throw in a pic or two to keep the visual-ites amongst us happy. There they are, dwarfed by those two disc spinners of mine. The little Majestic is both a DAC and a pre and, as I have found out, has a massive amount of gain. I don't think I've taken the volume control past 8 o'clock yet, there just hasn't been a need. The two Proprius monoblocks are actually smaller than a carton of cigarettes (that's a carton, not a pack, they may be small but they aren't that small!). They are actually only slightly larger than their power supplies. My initial impressions are extremely positive, the sound quality is excellent and the musical capability of this system is in no way related to its physical size. I'll throw in a couple of shots of the Majestic because I think it deserves it, a DAC with six inputs hey, who would have thought. And a usb makes 7, almost forgot. I'll try to dig in and get to the details over the coming weekend, stay tuned.
