Just a quick interim report:
I have received and hooked up the ncores. I join all the other grateful audiophiles on the tour in expressing my thanks to Jason for his generosity and good nature in allowing us to audition this new technology.
My system consists of a macbook air playing itunes front end; bel canto dac 1.5 taking the usb output from the mac; and Mark & Daniel Ruby speakers. The ncores are being tested in place of a bel canto s300iu integrated amp. So far, my impressions are very favorable: although I have always thought the bel canto amp had superb detail and articulation, the ncores may even be slightly better in this regard, and are slightly more "open", "natural," and "relaxed." I put those words in quotes because it is hard to describe exactly what the difference is, but all those descriptions seem to fit. Also, the ncores seem to have a slightly more extended top end--the high frequencies come through better. So far, the differences are not profound, but they are noticeable in my system.
I will give more detailed descriptions of equipment and software used, background, and listening impressions over the weekend, but I thought everyone who follows this thread might be interested in these quick initial impressions.
