CD Transport for the next 10 years.....

I would stick with Wadia, Theta, or Levinson. I have heard them all and owned the first two. It is really hard to beat the resell value, the build quality and more importantly, the sound. So, if you don't make it 10 years, you won't eat too much depreciation and will have made, more or less, the most with CDs during that time.

No, I mean the 31. I had the 31 and the 37 and kept the 31. The 31 is built like a tank and will truly make a believer out of anyone who doesn't believe in transport differences. The 37 is also good, but imho not in the same league as the 31!

I'm using a Sonic Frontiers SFT-1 and it's absolutely wonderful. The build quality and sonic performance are outstanding. In addition, the price you'd pay is typically less than what you'd pay for Wadia, Levinson, or Krell. Good luck!

I'd have to say the #37. I have never owned a #31, but I'm sure it is built like a tank. There have been write-ups (stereophile) that prefered the sound of the #37 to the #31--but as we know it's very system dependent and listener preference certainly plays a role at that level. They are both excellent, and the one that is right for you probably has more to do with your budget--they'll both last 10 years easy. Also, I recently bought a Genesis digital lens. It improved the sound, but the odd thing is, that it doesn't measure any jitter from the #37. It did at first--but now that everything has been hooked up and on 24/7--no jitter.
