Well... I'm definitely in the "B" group!
To me... the PS1000's, and especially the PS500's, are better than all others I've had, or demoed - they just sound much more like "real live music," than the others. For whatever reasons, I just don't hear any of the "artifacts" a few others reference.
But... I listen primarily to acoustical music, jazz, country, blues rock, chamber music, etc., not so much large, complex classical / orchestra works.
Though, as most phones >$1,000, I do agree they are way overpriced at their MSRP. Fortunately, I got mine at about 20-40% less than those lofty prices... and... consider them very reasonably priced at the prices I paid.
I agree....I find the PS500s to be a fantastic value just based on my own comparisons. I didn't pay full retail for the T1s since I got them in a package, but the 500s are around half the price and they have become my top choice for phones. I love how the T1s give me a neutral, more technically accurate reference to enjoy, and then I have the 500s to offer more immersion and a more organic experience with my music. I was just telling a lady friend of mine the other day how amazing it is to me that i've nearly abandoned my home audio rig for anything except home theater, and I even sold off my 2-channel preamp, which was one of the best on the market at its price point. I've just totally been overcome with love for my headphone sessions and they will take precedence over my speakers for music. I truly would have never guessed in a million years I'd be saying that, but that's just how I roll these days :)
