I just wanted to briefly let you all know about my experience with the FTA Callisto USB cable. I have compared numerous USB cables in my system and started the
USB Cable comparison thread on CA that now has a life of its own.
I compared this cable to the Light Harmonic Lightspeed 10G and the entry-level Gekko USB cables in my system. The Gekko had replaced the Lightspeed in my system because of a more resolved and quiet midrange. Nonetheless, the LF and HF of the Lightspeed were better than the Gekko and I started to look for something that would have the best of both worlds. I had the opportunity to get to know this cable and can now say that I found what I was looking for. It did take a while though.
The first cable I received was clearly inferior to both my cables and after a burn-in process I concluded that there either had to be a defect or it was simply plain bad. I reached out and they were extremely forthcoming in sending me a new one, trusting that I would compare both and send either one or both back, the latter in case it was not a defect.
After receiving the second one I inserted it without any burn-in into the system and compared right away with the Lightspeed, since that was the one which would need to be surpassed on all levels to make it worth my while. Right from the start it was on par with the LS, which was very surprising, since all USB cables have benefited from burn-in here at home, which bode well for a future comparison. 150 + hours later I sat down to do the real comparison and here are my findings:
- much better LF than the LS. not only deeper, but more accurate and, at the same time, more natural. transient attack was on the same level, but now had a more real texture and body
- mids were far more resolved, more calm, settled and poised. I gained considerable depth, a little bit more even than with the Gekko, which had been its major selling point for me. texture was more refined and even tone was better.
- the whole sound picture was now more integrated and cohesive
- HF on the LS, which had always been unsurpassed, now sounded slightly smeared, more specifically in the HF bloom and decay of harmonics, which now were more natural and well-reproduced.
Needless to say, that I won't be taking this out of my system, unless I find a worthy competitor. The Callisto definitely took away the itch and completely dethroned a cable that I have been using for almost 6 years. It is one level above any other USB cable I have had the chance to listen to in my system. Of course, ymmv, but I would strongly suggest anyone looking for a top-level USB cable to give this one a look.
Hope this helps someone. I do know it won't help me sell my Lightspeed, but I'll find another use for it.
