The last months I've again started to buy and sell more and more headphones, just for fun and because I'm kind of a "sick headphone-nerd" (maybe this is the wrong term, but ... you probably know what I mean...)
The PS1000 with the "right amp" might be the ultimate winner for some people.
My nephew -for example- likes the SRH-1840 far more than the LCD-2 Rev.2, I've given him as a birthday present. That's his honest opinion and just fine, because I know everybody has its own preferences.
As it belongs to me, I've tried out every high-end Grado you can get here, including the PS1000 and when it comes to my likings, neither the PS1000 nor any other Grado headphone I've heard so far out of different SS amps and tube amps, can impress me as much as the HD800 or even the T1 can do it out of e.g. the Meier Corda Symphony or other SS or tube amps.
The Grados are simply no match, neither technically, nor sonically and the wearing comfort without further modding is -in comparison to many other headphones- just awful.
Over the past ten years or so, I've really tried to like Grado headphones, but I can't. It's a matter of taste, but not only...
While money is luckily not really a problem for me and I've more than enough very fine headphones at the moment (HD800, T1, LCD-3, HEV90/HE90, SR007MK1, SR009, D7000, K1000, W3000ANV, etc.), I also have to note, that Grado headphones are totally overpriced here in Germany/Austria. (The only Grado I own atm. is an old PS-1 Pro, which I've bought for collecting reasons - I only listened once with it for a very short time and since then it's stored in its box.)
Here in Germany/Austria you pay ~2000 EUR (= ~2520 USD) for a PS1000 and for just 1000 EUR you can either get a HD800 or a T1 for example, with better build quality, better sound quality (to me subjectively spoken the HD800 sound three times as good as the PS1000) and without that cheap DIY-charme that comes with every Grado, in my opinion.
And a further side note:
The (to me fairly new) LCD-3, which has also kind of a DIY-style, costs also about 2000 EUR here, but I personally think it's worth the money and sounds just awesome with the Malvalve head amp three tube amp, I've bought especially for it .
I'm not often here in this forum, and out of my experiences with a -hopefully- open minded view of the things, I know that tastes differ and also that they can change quite a bit from time to time (e.g. sometimes I like the e-stats sound over the sound of the e-dyns, and vice versa - maybe it's kind of a special and different daily mood, I'm in, when liking this or that sound more than the other...).
I just read this topic and wanted to add my two cents to it, also because last weekend a friend of mine came for a visit an brought with him his recently purchased PS500, which I listened to with several amps and -you guess it already- I also didn't like very much. This friend, however, likes the PS500 much (otherwise he wouldn't have bought it, I think), while the T1 is still his favourite can, as he said to me.
I don't want to offend anyone of you, and as I said, maybe some Grados are just very fine for some you and better than other technically superior cans.
Hopefully you'll have no problem with my honest opinion on this topic, otherwise you're free to delete my post here through an admin or so.
Greetings from Nuremberg atm. and happy listening with whatever headphone you like,
