Yes, surprisingly, the Speltz cable is at least in the same league. Thus far I've only used it from my DAC to preamp (replacing Cardas Golden Ref), and it only has about 125 hours of burn in. I've tried many of the relatively inexpensive cables in the past and have never been much impressed, ie. I was somewhat cynical about the cudos given this cable. At this point I'm really impressed with this cable, at this price it is a no-brainer, it compares with much higher cost cables.
I hear really wonderful transparency/detail, tonal balance perhaps a bit on the warm side, actually, very similar to the GR in my system. I have only a couple of small nits thusfar, it seems a tad more aggresive on the attacks than the GR, the GR seems to accentuate the decays rather than the attacks. Image density and demensionality are a tad thinner as well, GR's really excell in the spaciousness category. Finally, there is a bit of confusion in more complex passages. The slight aggresiveness and confusion could be due to either RFI/EMI or lack of burn in. The info sheet that comes with the cable, and talk in the forums indicates these cables may need 500 hours to fully burn in.
I am somewhat skeptical that any wire needs 500 hours to burn in, 100 hours has been the usual mark in my experience. Anyway, I'm burning in the cable further at the moment, I will listen again at 200 hours, then 500 hours. Even as is, this cable is worth a listen, it may be all one needs! Keep in mind I'm only using the single IC, Golden Ref and PAD Dominus everywhere else, a full system of Speltz IC's and speaker cable, who knows?
