I used a Weiss DAC2 for a year with a 47Labs 4716 transport. To my ear they worked beautifully together and soon I was dreaming of upgrading the transport to the 4713 Flatfish(only $25k cheaper than the top of the line $30k PiTracer, anybody). However I began to notice a definite division in my CD collection. I found that there were those that performed sublimely well and those that fell well short. Too many fell short of the sound I was looking for. So I ultimately got rid of both and instead went for an ARC CD5 which allows a good many more of my collection to sound good or even great. But in all honesty I have to admit the best ones don't sound as good as the Weiss/47Labs combo.
