  1. Acoustic Research AR-M2

    Lightly used but in good condition--works well. Battery seems to be in good condition. (Note that it is possible to replace the battery, although it's not readily user-replaceable.) I'd updated the software o the last version of "Music Player PRO" that the player supports. I'll include the...

    Acoustic Research M2 Audiophile-Grade Hi-Res Portable

    I'm interested in using the M2 with the MrSpeakers Aeon headphones (a.k.a. Aeon Flow). Do you all have any experience with such a pairing? I posted a question about the M2 in the Aeon thread and got no acknowledgement whatsoever. Thanks!

    Acoustic Research M2 Audiophile-Grade Hi-Res Portable

    Acoustic Research offers a different model, the M20, that does feature Bluetooth. Unfortunately, the M20 is a lower-end unit; it apparently doesn't sound as good as the M2.

    Regarding batteries and best charging practices, I've found this site useful: http://batteryuniversity.com/ I'd say it's almost a "must-read."

    Thank you for your reply. I'm skeptical, as Acoustic Research has been promising various updates for over a year. As a prospective AR customer, I'd appreciate better communication; I'd need to know that my expensive purchase is adequately supported. Kind regards, Brian

    AEON, MrSpeakers' New Closed Back Planar Magnetic Headphone

    Hello! I'd like to pair an Aeon with an Acoustic Research M2 (AR-M2). The AR-M2 is a DAP that integrates a powerful headphone amp, one that I hope would suffice for driving the Aeon effectively. Still, I won't know until I've tried them. Can anyone here comment on the performance between the...

    As per AR Hong Kong's Facebook page. (It's likely you'd need to be a Facebook subscriber to view it.)

    Acoustic Research M2 Audiophile-Grade Hi-Res Portable

    Hi, cirodts - Do you listen to any classical music? I have heard that the M2 may not be the best player to use for such music. Thanks, Brian

    Review: Questyle Audio QP1R - With Multiple Headphone and IEM Pairings

    It's conceivable; the 1R revision apparently uses different components. @JerryLeeds - Volume notwithstanding, does the the current QP1R sound the same as the original release?

    Acoustic Research M2 Audiophile-Grade Hi-Res Portable

    besati, thanks for your post. If my understanding is correct, firmware 2.6 is an unreleased beta, one that AR has abandoned.

    @gannjunior - Hello! Apparently, Acoustic Research will soon release a major firmware update; I hope it will address many of the M2's shortcomings. Best regards, Brian

    Acoustic Research M2 Audiophile-Grade Hi-Res Portable

      Hello, @Leoipod -   An AR representative reported in this thread that AR plans to release a major firmware update to coincide with the upcoming audio show in Munich. He wrote that the updated firmware would be "announced" in mid-May.   Best regards, Brian

    Acoustic Research M2 Audiophile-Grade Hi-Res Portable

      What version of the firmware are you using? It's my understanding that recent firmware revisions support gapless playback for many types of file formats. AR also mentioned in the past that upcoming firmware releases should cover all formats. (The next major revision is apparently planned for...

    Best DAP for inefficient headphones

      I was referring to the battery's total longevity. I know nothing about the Aune, but Onkyo offers a DAP--a pricey one--in which the battery is bonded using strong adhesive. When the DAP's battery stops functioning Onkyo simply expects the user to discard the entire unit, never mind that it...

    Best DAP for inefficient headphones

      Hi, @fgriggs -   I mostly listen to classical music, so the Aune's lack of gapless playback is a crucial omission. (It's a significant consideration for popular music too, as albums such as The Dark Side of the Moon will stutter rather than play as continuous streams of music.) Indeed, the...
