Any idea which headphones I’d like?

I really like Grado cans (and their headphones too) and since I rarely listen to my main system with phones (I do use a simple system with the Grados for bedtime music while reading) I'm fine with the less expensive versions, including the amazing 325e. Just got a 325X to see if they're better, and so I don't have to raid my bedroom system for the phones...run all the way to the other side of the Mansion? No way man...the 325X is a little better, and man...just a great thing...I run either pair with a Schiit Magni 3 (I have 2 of these, which adds up to a Magni 6) and that pairing sounds superb.

Audio-Technica Corporation (Kabushiki Kaisha Ōdio Tekunika) may be a Japanese company that designs and manufactures professional microphones, headphones, turntables, phonographic magnetic cartridges, and other audio equipment. it had been established in 1962 in Shinjuku, Tokyo, Japan, by Hideo Matsushita as a phonograph cartridge manufacturer. In 1974, the corporate developed its first headphones, the AT-700 series. Interesting modern models include the audiophile ATH-AD series and professional ATH-M/R series.

Dynaudio has always been a high-end hi-fi brand - and it's not looking to give over any of that market any time soon.
