Unfortunately not using the TL51X with the EC, but I use it with a LessLoss DAC 2004 MkII. Previously I had the North Star 192 combo. For comparative purposes I tried the North Star transport with the LessLoss. It performed very well. The North Star had a bit more oomph and speed while the CEC had an overall smoothness to it that is hard to explain. I know it's cliche but it did sound more like vinyl. It conveyed more of the pace in music that I enjoy.
Overall I was very surprised and pleased with the results of this transport. For the price it would be worth trying with your EC.
