Still have the AD, but comparisons here won't matter because I don't use stock cables on either!
And neither do I. Vanquish ftw.
The cable I am using is similar to the Vanquish, but instead of the copper/spc, mineis copper/pure silver DHC Fusion Type 4, very similar bleeding edge design. I didn't have this cable available when I owned the PM-1. Just made adapters yesterday, 2.5 mm to mini xlr. My cables have had extensive use, so no need to worry about burn in.
After having the PM-1, in the beautiful presentation perfect box, these some in a much smaller package....cardboard box, nicely designed (silver fabric look with Oppo logo in silver) the same carrying case that came with the PM-1. Look and feel is much like what I remembered with the PM-1, except the black piece around the cups, and plastic, which look very nice. Big surprise is the high quality of the pleather used, feels more like real leather than any other pleather I have ever experienced....nice, nice, nice!
Initial test tracks reveal a beautiful sound I am going to like. Great tight bass, gorgeous mids, very nice treble with lots of air (but consider, this is not the stock cable). I am really liking these! They sound very detailed and open, with a big soundstage (cable affect maybe)! They will complement the Alpha Dogs very well, more open as expected. The tizz a 4 kHz I heard with the HE-560 does not exist with these, comfort is easily on par with the 560. I am using Telefunken 12AX7 tubes in my tube amp, using the speaker taps at 5wpc, I am getting a nice rich sound with everything sounding more natural then the 560's had. Been a month or so since I had the PM-1, so can't really compare the to them, plus I didn't have the Telefunken's or the new Type 4 cables then....but these hit the bullseye for me. I probably will pass on the HE-400i after reading jerg's impressions, and hearing these! Would like to hear the Fostex RP next!
Don't want to comment more on the sound right now, as they are so new....but with this cable the soundspace/soundstage is much bigger than I can remember with the PM-1....give a lot of credit to this cable, and the Telefunken tubes as well. Like them very much!
