Just reported on the JCAT Isolator/ISO cable in a post under the USB Isolator topic. Adding my feedback on the FEMTO card in this post.
I just purchased a USB FEMTO card which replaces a JCAT v1.1 USB card in my dedicated audio PC. The FEMTO card, along with a JCAT Isolator/ISO cable have been in my system for about a week and a half and seem to be well burned in.
The FEMTO card was an easy replacement. It fired right up when I turned on my PC and I didn't change any JPLAY settings at all.
I am very happy with the results. Immediately I could hear areas that the FEMTO card improved over the non-FEMTO JCAT card but wanted to wait for the new components to settle in before reporting. I'll also say the I have listened with the Isolator/ISO cable in and out of my system so I can "isolate" the benefits of each. See the post in the JCAT Isolator topic for my perceptions of the JCAT Isolator w/ISO cable.
The FEMTO card is a very nice step up in sound quality over the non-FEMTO card. The music flows much better; a combination of having a smoother and more refined inner details across the frequency range with better bass extension with better articulation. I really like the changes the FEMTO card makes to the sound of my system! Highly recommended!
The JCAT Isolator/ISO cable augments the changes of the FEMTO card plus adds to it. I couldn't be happier with this purchase.
Marcin great job pulling together some great quality products! Looking forward to seeing what's the next new products
I am using a single PC driven by a 100W linear power supply. Marcin has been working on me to go to a 2-PC set up! Always another step to improve the window into the music -- The reason I enjoy this so much!
