I too own the Au24 speaker cables, and tried their RCA interconnects on loan. Matched against my personal reference van den Hul The First Ultimate interconnects, I thought the Au24 was very good but not quite as accomplished as their speaker cables, and not superior to TFU. Specifically, I could identify some very slight coloration and smearing, and a hint of compression, that was absent from the vdH TFU, though in general the Au24's performance was probably better than that of my previous interconnects (the ones I replaced with the TFU).
(I should note that my interconnect auditions include both conventional subjective A/B's, and also more controlled bypass tests, where each IC is compared with its absence from the chain, to help determine what the objective effects of each are in isolation and not just in relation to each other. My preference and goal is for interconnects that degrade the input signal as little as possible.)
Dale has offered for me to try out the Orchid XLR, which I will put up against vdH The Second XLR (my balanced reference), in a system with a balanced DAC, preamp and power amp. In addition, I will get a second audition with the Atlas Navigator, this time in XLR form, which Dale previously lent me with RCA's. (I thought it was quite good, especially in terms of top end extension and dynamics, and though it didn't quite manage to overthrow TFU for me, it was very competitive with an RCA pair of The Second.) So we'll see how this shakes out -- The Second is supposed to be at its best in balanced configuration, and I'm a big fan of the vdH carbon sound, or lack thereof. (For those unfamiliar with the line, vdH offers interconnects with conductors made from carbon fiber instead of metal, The First and The Second, but The Orchid is not one of those.)
