I was the lucky first on Todd The Vinyl Junkie loaner program and have been listening for over 3+ hours and I agree with everything you have written except I am not noticing the treble issue mentioned. Todd did spend some time with them so they may have more hours on them. Also, and this could be factor is the 5 foot split single ended Cardas Clear headphone cable. These are a must audition headphone. I currently have them paired with Roon feeding a PS Audio PWD MKII connected balance to a RSA Apache.
