That is nonsense. He didn't directly compare them. If he directly compared them, he would have had to use them side by side. His comparison is about a month apart, nor has he had time to dial the VTF3 in; he just received it. I did hear a VTF3 mk5 that was dialed in a room and a month later a PSA S1500 that hadn't been dialed in- guess what, the VTF3 sounded great and the S1500 sounded like nothing. I don't go on to make comparative statements between the two based on that experience though. The XS30se might have more headroom in music frequencies, but I would be surprised if it had any qualitative advantage at all beyond that.
