@ calvinj, congrats on the nordost Tyr and the EH 6h30 tubes!, Keep me posted on the sound of it all, after your tubes break in, I would put the original interconnect back in to hear what the tubes are actually doing, since you are familar with your last interconnects!, then put your new tyr interconnects in and give me sentiments of all of the sound, I look forward to hear what you have to say!,, cheers!
