I have been playing bass for 28 years and have owned a multitude of high end amps. I had been currently using a WT800 and WT400 through a Bergie 310 cab. About year ago, I sold a Trace RAH600SMX head (to get the WT800) that I really missed as soon as it left my posession. While there's no doubt that the Eden heads sound great - I have to say that the RAH600SMX sounds even better to me. I used it this last Saturday for the first time and my sound was tight and very "tube-like". I love the dual compressor! I've seen a few threads here lately where the Trace stuff was getting some negative comments in the reliability and sound catagories. My last RAH600SMX I used for 6 years with absolutely no problems. I also had a Trace 1210SMX combo that was awesome. What's the current feeling on the newer (higher end) Trace stuff? Any other satisfied customers out there!?
