Well, I called around yesterday to see if any local shops had a Duet in stock and low and behold I managed to get a used unit that had 3 days of use at a studio. I also purchased a 1/4" phono to RCA pair to run my sub from the headphone output. I can sum up my first impressions as WOW! The reviews are dead on for this unit. This is the tightest,deepest and most articulate base I have had from any of my systems. The sound is dynamic and punchy yet smooth and revealing. I was worried that the highs were not going to be to my taste which is to the warm side but these are crystal clear without harshness. In fact, I was able to listen at high levels with absolutely no audible distortion. My Dad sat in to listen and agreed that this is the best sound that I have had from my system. I am using a pair of Senn HD 650 right now as I type and I am very pleased with the head amp. I think that this is one of the nicest looking products on the market as well. The portability factor is a huge plus as well. I will have top notch sound on my weekends in Whistler or while on vacation.
Thank you to those that replied and to those that read this thread let it be known that I give this product a huge thumbs up!
Cheers!
