Yes, I was one of the very first to receive the JCAT USB XE.

The Technology

Some technical data:
- Emerald OCXO (oven controlled oscillator) ± 0.005 (± 5 ppb) stability
- ASM3142 USB 3.1 host controller
- LT3045 linear regulators and filters eliminate noise interferences from a PC

Compared to the USB Femto Card, USB XE has a heat sink.



The external power supply with 5V via a high quality linear power supply is very important in my opinion.



In the picture below the PCIe card is installed on the left.



The Sound

A noticeably cleaner sound, better spatiality, more audible bass range, very finely resolved in the highs. In terms of tonal balance, the sound has shifted a little towards the treble - but very pleasant.
