It sounds like the SR325x is moving away from its original edgy, metallic and punchy sound into a more mellow softer hemp-like sound? Is that really true? Then they are no longer what I am looking for. Hopefully the 225x will stay on the brighter side of the road. I am also looking forward to someone sharing their impression of 225x.
To my ears, they're not "edgy" and "metallic", but they're still plenty "punchy". They do sound different somehow from the
325e's, but I'm not yet able to determine exactly what it is. I sold my 325e's about 6 months ago, so I'm not able
to do a direct comparison.
Somehow, though, I feel/recall that I liked the 325e's more. I recall and or sense that they were more detailed and even a touch
warmer overall, especially from the bass up to the mids. I don't have an excited urge to listen to the 325x, which for me is always
a reliable sign that I really like (or dislike) a particular set of headphones.
One thing I'd like to mention is that the 325x's are really nicely made compared with prior models in the Prestige Line.
They "hang together" much more solidly, the cable is covered with some type of nylon(?) material which doesn't get
hung up as easily; and it's softer and more pliable. And the headband is thicker with some very nicely done white stitching
close to the edges. So, credit where it's due and IMO Grado definitely deserves credit in that regard.
My 500e's and RS1i's are still my go-to headphones for serious listening.
