Thank you Natan 6355 for your initial report.
Interesting, you comment that "Going from wired to wireless on the same song I felt the need turn the volume down 1 step on my CAT preamp " says a lot because Ken Stevens steps are of few dB each - I always had difficulties to find a sweet spot in-between.
Thank you again
Simon
P.S. If you can do aslo A/B comparison using hi-rez downloads (e.g. 24/96) - whatever your equipment allows, it will be very useful to hear as well
