Unfortunately I moved my Mad Scientist Black Magic USB cable on, so cannot compare it to the the MS Black Magic Ultra.
Planning to evaluate it next week after 300 hours.
A friend has just received his, and says after 12 hours the ultra pulls away from the original with much more detail and soundstage.
It's truly remarkable. However, it took a while to really break in and open up. I would say at least 50 hours, maybe more. I practically no longer hear any difference vs. my previous USB, the SR Galileo SX. The Mad Scientist Ultra USB is actually a bit more musical. Galileo maybe has a bit more details and "sparkle", but I think I prefer the Mad Scientist more. And for the price (compared to Galileo) is a no brainer!
Thank you Thyname, that's just what I wanted to hear.
I found an offer for a used SR Galileo sx (anyway 1600 €) and I was about to get it, as I took SR Atmosphere X Reference Ethernet Cable and I'm very happy with it. But now the choice is even more difficult, since I thought of combining it with the Active Ground Block if to optimize its effects
A friend said about his Black Magic Ultra:
"The Ultra resembles the original but pulls away by imparting much more detail and soundstage while improving timbre and virtually eliminating tonal bias."
Ozzzy Glad we were able to make you happy. Speaker cables will be ready to try between 20-27th of the month. If anyone else wants to try usb cables or interconnects let me know. I will be sending more demos out.
Compared Diamond and Callisto 1:1 few years ago, think it was one of the Callisto's earliest release...
Callisto won with classic knock-out in first round.
Delivery from New Zealand to Sweden was much faster than I expected. Now its here and I look forward to hear more as it burns in. But it sounds very good so far.
