I have the krell kid and the wadia i 170. They are really good however the wadia i 170 is better. MY wadia was sent to steve at GNS co for mods. The wadia bypasses the i pods dac and the krell kid does not. The wadia sound depends on your dac that you are using. I had mine hooked up to ensemble hi dac and the sound is great it blows the krell away as is should. I really dont use a cd transport anymore the future is in ipod transport and music servers. I am now using the MSB ilink transport to my dac. Its cost 2300 however its worth every penny i cant tell the the difference between my ensemble transport which cost 4 times as much as the MSB ilink. I take that back the MSB has better mid and highs to me. I would not spend mega bucks on cd transports you will just be wasting your money.
