I've had a quick dalliance with Sennheiser HD558s. Not enough bass for me and open backed which leaked massive amounts of sound! I'm now leaning towards the Senn closed 25-1 II or your Amperiors Dale. Decisions decisions.
I was thinking to mention the new Logitech UE-6000, which I'm going to video and text-review today or tomorrow. My hesitation is that while it has a very strong bass like the Philips L1, and unlike the L1, applying bass reduction results in a bass that's as good as the Amperior (on direct compare), it has a strong treble that's very comparable to the Shure 1840. And mids are uncolored. And it's noise-canceling, and cost in the U.S. is $200.
So while it looks like the quadruple** bargain of the year, I don't know about that treble. Sibilants may be an issue.
** Super strong bass if you like, bass like Amperior if you prefer, treble like the 1840, and noise canceling.
KRK KNS8400, B&O H6 (Green), B&W P7, Shure SRH1540, Bose OE2i, Audioengine D3/Microstreamer DAC/amps, Zen Head amp.
Not a fan of more pronounced treble, as you note. Would the Senn Hd25 I ii be a justifiable leap over my AKG450s please, considering the original price of them is comparable to the Senns?
The Amperior would be certainly, but I just can't vouch for any difference with the HD-25-1-II since I haven't heard it. It might sound essentially the same, or not.
Here's one person's take (last post):
And on this page Tyll concludes his comparison:
Great, thanks Dale. I'm not going to leap but have a good think (although listening is better...) and hopefully demo both somewhere.
I haven't heard that particular AKG but from what I read it went down in price for a good reason. It seemed like WHF were a bit generous with their score originally at its price point. I may have gotten rid of my HD25-1 II in favour of the VModa M/80, but I loved the Senn and got good use out of them for 5 years, it's a great portable with very good isolation, used a lot in the industry (not endorsements).
