If you mean Joseph's impressions, Then yes, I have been following it-Since his pair has also new drivers maybe it needs some more burn in, So you can't still compare objectively.
Anyway, I learned today that burn in exists! That is a great lesson, I wasn't always so sure about it, But believe me, Those are not the same headphones anymore!
I went and got the following for you, from the PS1000 appreciation thread.
For those who might not know, I did another (2nd time), between my PS1k, and the e version.
I should mention that the Yamaha RX-V2220 that I had use as a pre amp for the first PS1k vs PS1ke comparison, is no longer with us, it died a horrific death a few weeks ago, and has since been replace by a Yamaha RX-A850, wich was not used for this comparison.
For this comparison, I used the same recording that I always use, and am very familiar with.
I did most of my listening using the headphone output of a vintage Marantz 2235B. This reciever has great bass extension, and a very warm, ritch sound signature. I also used my Little Dot 1+ with Voskhod tubes. I went with the LD 1+, because it's the amp that I usually use with the PS1k.
I listened to my old PS1k first, and then switched back and forth between the two, as I went through the CDs that I always use for comparing headphones.
The first thing that surprised me when I listened to the e was the apparent absence of bass. This floored me, because in the first time that I had compared the two, the e seemed to have deeper bass than the old PS1k. This was true for both the reciever's output, and the LD 1+.
The e's mids had slightly more presence, and warmth. but the soundstage was a bit narrower. This is basically what I had concluded the first time, so no major surprise there.
The highs were more similar than what I remember. This might be due the fact the e now have a few more hours on them. They were still a bit more forgiving, but the difference was less obvious.
Sadly, though not surpringly, comfort with the e was still an issue, the portruded drivers were pressing on my smallish ears.
Even if I came to the same conclusion, I'm glad that I had the opportunity to do another comparison between the PS1k and the e version. I can totally understand why M.H. and others, prefer the e's more balanced sound.
To me, the old PS1k sounds more exiting. This is also why I bought a pair of n.o.s. RS1, they might not be as neutral sounding as the i version, but they sure sound exiting.
In my opinion, there is no right or wrong in this great hobby of ours, there's simply, one big gray area. This is why I often use words like, ''In my opinion...'', ''I think that...'', ''I find that...'', ''as far as I'm concerned...'', ''the way I see it...''. I also try to give credit where it's due. So I will leave the conclusion to Macedonian Hero, who I think, summed it up best...''the PS1k, and the PS1ke sound a lot more alike, than they do different''.
M.H., don't hesitate to correct me if I have misquoted you, I have good excuses, so I won't be offended...partly because my native tongue is French, and also because I'm so strongly medicated.
