Нашел интересный довольно таки обзор на сабж от Баба Катца с Иннерфиделити. Правда он на инглише.)) Если кто сможет перевести лучше чем гугл, то будет здорово. A Serious Listen: Astell & Kearn: AK T1p headphones These Astel & Kern AK T1p ($1199) cans are among the most beautiful, striking designs around; an artsy, pristine piece. Beautiful brushed metal, luxurious comfortable pads, lightweight, produced by a partnership between A&K and beyerdynamic. This is a worthy sight on anyone's head. Smaller in diameter than my reference Audeze LCD-X, but still circumaural. Each A&K phone is hand-made, individually serialized: I'm reviewing #335. It comes with balanced and unbalanced cables, but I auditioned unbalanced. I'm not a shy guy. If I don't like a headphone, I'll pull it off my ears within five minutes! So far, I've had the Astell & Kearn AK T1p on for over 40 minutes and I keep wanting to check them out—so there must be something about them that's keeping me listening. They call it a "semi-open" headphone...I don't hear any closed-in artifacts, they sound very transparent. Initially I find their sound attractive, warm, natural. But still there's something that's bothering me about these cans. I begin to feel they're a bit "polite", they never seem to kick with any recording. What's that about? To get to the bottom of the matter I played one of my reference recordings, my own recording of Rebekka Pidgeon singing "Spanish Harlem" from her album "The Raven" on Chesky Records, the 176.4 kHz HD tracks "Bob Katz remastering, special edition." Now the issue becomes clear: There is a presence boost, centered at approximately 5 kHz. With the A&Ks, Rebekka's warm voice has become strongly sibilant. I know what she sounds like in person, plus, having heard this recording in many places, I know it is warmer and not so strongly present in the 5kHz range. My diagnosis: the reason this peak comes on you slowly is that it is an extremely wide (low-Q) resonance. This is clearly a design decision on Beyer and A&K's part, to produce an immediately-perceived transparency that can be attractive to a lot of listeners. In contrast, a high-Q resonance (a sharp peak) can sound fatiguing, not the case with the A&K's, or they would not have passed my five minute test. In fact, they stayed on my head for a few hours! Too many headphones have instantly-identifiable sharp peaks in their responses, like the Sennheeiser HD 800's, but this is fortunately not the case with the A&Ks. These A&K cans feature second generation "Tesla" technology, which they claim eliminates even the last traces of resonance in the high frequency range. Next, I check out some classical music: Also pre-installed on this A&K demo player, a high-res piece from Chesky, "Waltz of the Flowers", 24/96 from HD tracks, Bruckner Orchester Linz. This Tchaikovsky recording reinforced my impression...that these are destined to be classical music lovers' headphones. While I found the presence boost initially off-putting, it was easy to get used to, just a bit too "hi-fi" for this critical audiophile. But I'm sure these phones will be very attractive to any music listener who desires a lightweight headset that feels and sounds great. If only we could turn down that 5kHz range and fill in the lower midrange and bass just a hair, these A&K cans would be an amazing piece. When I switched to my Audeze LCD-X cans, the Bruckner orchestra immediately sounded more attractive, with more warmth and body, string basses regained their drive. Then I switched to my custom-built M3 amplifier and the DAC from a Slimbox Transporter so I could play a wide variety of familiar sources from my collection in JRiver, alternating between the LCD-X cans and the A&Ks. I did not use any compensating EQ for the Audeze, so readers will get the raw dope. Since I have Rebekka's original master on my server, I replayed the song. With the LCD-X, Rebekka's romance was back, her voice instantly recovered its warmth and fullness. A bit too much, in fact, which was one of my motivations for equalizing the LCD-X in the first place. Still, her voice sounded more correct on the Audeze. I do think this presence boost is the origin for my impression that the A&K sounds too polite. This is not a rock and roller's can... Steely Danners and Patricia Barberers will like the A&K more than Led Zeppelliners. Classical and jazz lovers could easily fall in love with this can, especially with its lightness and beauty. Nevertheless, I strongly believe there does not have to be a "genre headphone": there is no such thing as a "classical music speaker" or "classical music headphone"—or a "hip hop headphone", though Apple and Beats would like you to think so. When a transducer is absolutely accurate, every style of music should sound right. But life is a compromise, and especially considering their great comfort, clearly the A&K's will satisfy a large group of listeners who like a relaxed, transparent sound and for whom power and punch are not high priorities. I know a lot of women (and men) who will fall in love with this combination of styling, light weight, and transparent sound. I definitely would not kick these beautifully-made, lightweight A&K's out of bed. With the A&K, there's barely a wink of robust body and deep beauty. Though the A&K definitely have some bass, it's, well...polite. So personally, I keep returning to my Audeze—for as long as I can tolerate their weight. Still, you have to pay more than a $500 premium for the Audeze! Are there any more accurate headphones than the A&K in the under $1200 category? Do we really have to invest close to $2000 to satisfy our appetite for musical body and soul? We shall see, in future Katz's Corner investigations.
