I ordered a Woo WES (stock) and an SR-007 recently after having heard them (in the maxed configuration) at a meet, but I only have relatively cheap sources (a xonar essence soundcard and a USB 'ODAC' from JDS Labs - but neither have balanced outputs) at home. The sources sound great to me with my previous headphones, but I've never owned anything with balanced inputs before, nor anything as high-end.
If you connect via RCA to the Woo WES you have to use "phase splitter" tubes, apparently. Jack told me that they're included with the WES. I'm completely confused by what that means, though...
Could anyone offer some insight as to what that entails exactly, and offer me any suggestions as to whether the difference in sound quality would be significant between connecting via the balanced xlr inputs vs the RCA inputs? My understanding of "balanced" was just that there was less noise along the lines, but I can't get a clear explanation.
I'm contemplating adding a $1-$2k usb dac with balanced xlr outputs to the mix, but I'm trying to get some idea as to whether or not it would really pay off.
