I'm sorry if I wasn't clear in both of my prior posts, but the Utrasones & the Beyers were both using their stock cabling with the 1/4" plug. Only the Senns were cabled balanced. So the Beyers I preferred over the other two were playing under the same conditions as the 2500's.
Also sorry if we continue to disagree so vastly on our sonic preferences too, Alberto. But I find the CD3k's barely listenable, and not even close to being worthy of the cult status they now enjoy after being discontinued. I really wanted to like the Ultrasone Proline 2500's, and had every hope for the best until I put them on my head. The headband is completely inflexible, with little padding on the top. The earcups are not as large as either the Beyer's or the Senns, and also not as deep, so they are not as comfortable as either. Sonically they were like mud.
I could have blamed the associated gear, but the Senns and Beyers sounded fine. Not to mention the Meridian is a well-regarded source, and the Rudistor amp was provided by you. Can't blame the Grace 902 like you did at the National meet.
I do a pretty thorough job of qualifying my opionions as just that -
my opinions. And of course it was under meet conditions. But I think this test had a fair amount of controls and references.
