.After hooking up the M51 I spent a couple of hours doing A-B testing with the same tracks, between that (Sonos/M51) and the Renew, both via XLR into the Primare . . . . All I can say is 'Wow!', I was more than a little surprised and impressed - the M51 is quite something - in my system it gave a decent step up over the Renew, perhaps to a similar extent than the Renew did over the Sonos/SP32. The M51 revealed detail in the tracks that the Renew simply didn't recover - it gave a clearer sense of the acoustic space the artists were performing in; there is a natural audible decay and reverberation to the instruments and vocals that is clearly there in the recordings that the Renew simply didn't resolve. It also added even greater separation, detail and texture to vocals and instruments than the Renew achieved, and added significantly more three dimensional depth to the sound stage, whilst really striking the ideal tonal middle ground in that lower mid/bass region - fuller and more balanced than the Renew, and tighter and more defined than the Sonos/SP32.
As I say, I was more than a little surprised, and took the demo really only on a recommendation. I certainly didn't expect it to best the Renew, but hoped merely that it might close the gap a little.
Given its £1500 price tag, the fairly extensive feature set (HDMI inputs, re-clocking etc) compared to most DAC's, and of course the incredible sound quality I experienced last night, it's an absolute steal.
Needless to say, the I have decided to send the Renew back for a refund, and will be getting an M51. With the £2,500 change, I will probably get the matching M50 streamer that is due out shortly, which will give me 24bit streaming and possibly another step up in sound quality over the Sonos - plus I'll still have change!
Don't get me wrong, this has been a pleasurable experience, and a real eye-opener to me, on the huge importance of the DAC in a digital streaming set-up. The Renew is a fabulous sounding piece of kit in its own right, and for someone adding this to a system with lesser DAC's, the improvement will be substantial. But given the existence of the M51(and possible other DAC's out there up to the value of the Renew/Akurate), one has to question the value for money of the Linn offering - and that is even without considering the full price Klimax DS.
Many thanks for all your help Cno (and others), as always, the journey continues...
