Could this be a 'giant-killing' tonearm cable?

The filigree detail that you mention is all well and good but I want to HEAR what's on the record and not have the thing glossed over by a wave of discolouration.

Interesting comment, Andy. What I heard with Marco's 423.5 'special' in my system was a combination of great wealth of detail within a fantastic (and I mean strongly better than with my Dynavector cable) soundstage with greater width, depth and, intriguingly, height. The sense of a real space with dimensionality was palpable and all three of us heard it clearly.

Now, I think that there is an important symbiosis going on with tonearm cable, SUT, and interconnect to phono preamp; in fact, I think this is critical to success. So in my case, the 423.5 'special', Choir Audio SUT-H7 and Tellurium Q Black worked very well together although Marco preferred the G1000HD/WBT in the latter position. I have ordered a 223.5/WBT to compare with the TQ and get the very best symbiosis I can achieve.

As for your comment about valves, bear in mind that my system is all solid-state, so I'm not sure that the chosen technology is a factor.
