I really like the C-Marc. I had seven RCA cables in my home at the same time,ranging in price from $35.00 up to $1000.00
I had a difficult time choosing which RCAs I should go with,but in the end the Callisto+C-Marc was the best sound overall for my system.
I did a video review of the cable shootout. Keep in mind my primary focus are headphones,and my comments made in the review about how the cables impacted the sound of my nearfield 2.1 system are based upon using entry level speaker cable,which im in the process of upgrading.
Nice. The Callisto a genuine high and audio component, and affordable at that! In fact a bargain upgrade. Don't forget they also do superb Ethernet, RCA, XLR and Power cords. High end cables at real world prices.
I am a big fan of FTA Callisto usb cable which I use for over 1 year , unpowered version, bought sh from Goran ( Golum).
It is a fantastic cable with very dark backround and palpable presentation , I would say on slightly warmer side.
Two month ago a young Polish engineer asked me to try his usb cable in my system.
I did not expect too much but the reality surpassed largely my expectations. In my system is even more precise , with even better than Callisto 3 D soundstage and quiter backround.
Very neutral timbre.
I decided to get one, the price for unpowered version is around 400 euro in Poland.
Will keep both - Callisto and Audio Phase usb, this is the name of Polish small company.
I have no commercial interest in Audio Phase, just to be clear.
I sold a Ganymede recently, with the 2020 spec and new plugs. I tested it in our system with Aries Cerat Kassandra and Genus SET, and it is a superb cable. Really natural and solid, with great details and timbre. It is the best interconnect I have heard so far, and is surpassing the cables we have heard at twice the price. I have it on a promotion at the moment.
Very interesting. I had not heard of FTA cables until a few days ago from a trusted friend. Appears the FTA USB may be besting Nordost's top rung. Will need to hear this for myself soon!! Word is spreading
