I owned a Moon I-5 for over a year and found it to be very well made, easy to use and integrated well with my subwoofer. Simaudio is also a great company to work with. However, I also was never able to get it to sound right with anything I tried it with. I'm not saying it always sounded bad, quite the contrary, sometimes it was magical. But in my room it had a tendency to be lean and a bit sizzly on top no matter what cables or speakers I used it with, and over time that became unbearable. I eventually went to a tube preamp mated to a solid state amp. I think that move in itself may tell you that my tastes could be different from yours, but I thought I would just offer my experience.
