I've had the I-7 in my system for over a month & it is the best sounding integrated amp I've ever heard. It has awakened my B&W nautilus 803s speakers & reinvigorated my interest in audio. The soundstage is absolutely huge , the bass is unbelieveable & the seperation between instruments is astonishing. Whether I spin vinyl or CD I'm delighted with everything I've heard so far. It does take lots of breakin & it runs very hot, but thats not a bad thing in Canada in the winter. You couldn't pry this amp from my cold dead hands.
