I took the plunge and ordered a Platinum from Alex. He was gracious and finished it in black. It came in yesterday. I ordered upgrade Eidolic connectors on both the amp and headphone ends. On first sight, it made my Red seem wimpy.
I put on the Purist Audio disc and let it play 24 hours. Purist Audio suggests only 6 hours and 40 minutes is really necessary but hey I had to sleep and go to work.
I am using it with my HE6. The first reaction was there was a volume increase, which really did not make sense to me. The more I have listened, I think it is just more clarity with a blacker background. The music is more intimate. The bass decays very naturally. Female vocals are really enveloping like you are in the room with them.
I am going to do some more enjoying rather typing for now.
I should mention Alex indicated Mr. Speaker and Cavalli Audio will have the Platinum at their tables at Axpona on 4/15 thru 4/17.
