I demo'ed one for about a week. Used with my Krell FPB 200, Krell HRC preamp. B&W Matrix 800's with Purist Elementa cables. I wasnt impressed with the 300 at all. The detail is excellent. If there is anything on the CD, u will hear it with the 300. I just couldnt listen for more than 30 minutes or so b4 I had to turn it off or just lower the volume to very low levels. I thought it was way to bright/harse to listen 2 for extended periods of time. Thats just my 2cents tho. I ended up buying a Wadia 850. It was more $ but I'm happy with it.
