Actually, the PS-1/HP-2 was designed for the studio. They were made as studio monitors, so not really headfiers. And here is a
stereophile review of the HP-1000 (its about the Melos but a large chunck of it is the Melos/HP-1000 combo), so definately there IS a major publication review. I trust my ears, so it doesn't make a difference to me - but if some need a major publication review before giving something credibility, then there ya go.
Yes, they are used unless you can find a NOS pair (doubt it), but I'd rather buy something used that will increase in value than something new that will decrease in value. You can actually use it for several years and sell it for a profit. Pretty amazing. But my HPs are going nowhere. I hope to have them for life.
The PS-1000 sounds interesting, but it seems colored like the PS-1 with lots of bass from the impressions so far. It also seems like a GS-1000 with metal slapped on for almost double the price - I could get a machine shop to do that for change.
The GS-1000 is the most I'll pay for a phone that is colored like that (fun phone).
I prefer the HP-2 to all Grados - like you said nothing "jumps out" - that's what I look for, the music delivered as is. Not colored... However, there are times where I want that coloration or something to jump out which is why I like and still have the GS-1000. Get the right system behind it and it can be bliss, plus it has the RS-1/GS-1000 timbre which none of the metal Grados have - but if you have some weak spots in your system, they can sound bad or mediocre.
I definitely am not knocking the Denon as they are very good headphones, all of the ones I've heard, but they just don't fit my taste. In fact, I listened to the D5000 (markl) modded at a meet and ended up behind way more impressed with the Stax Lambda at the same meet which can be bought for $400, amp included. So, I bought it and then gave it to a friend after comparing it to the phones I have, including the GS-1000. That should put my preferences into perspective.
I have not heard the D7000, so that is worth clarifying. I don't have an opinion on that one, but I haven't gotten into the Denon sound. I think it's the "club bass" sound that may gel with others but not me.
These are all my tastes, so I'm not arguing or disagreeing- just laying it out.
- so you gotta pay up 
- Denons never did it for me. They do many things well and really nothing wrong but lose out for my tastes to the lively Grados. You could definitely help your wallet out if you like the Denons better though. They are more reasonably priced[/QUOTE]
