    Bass Boost Detail: Bass frequency below 100 Hz gets about 5dB boost. The boost gradually decreases from 100Hz to about 500Hz where it reaches the normal non-boosted level.
     
    Now that the HA-2 has been officially launched as of this afternoon (February 20th, 2015) I thought it would be appropriate to start a new discussions thread that was originally started in the Sponsors Forum when we revealed the HA-2 and the PM-3 to the public for the first time at the Rocky Mountain Audio Festival in 2014.
     
    All those who have beta tested the HA-2, we thank you, and we hope that you will contribute immensely to on the HeadFi forums. Your NDAs are over, so if you had any tribulations about posting, don't. Post to your heart's contentment.

    20hz to 200kHz!

    That's pretty impressive frequency response.
    It can cover the real 24bit 192kHz files.

    When can we see this on Amazon?
    how does it sound? Does it worth $299?

    You realize that 16/44.1 can cover the same frequency range as 24/192. Even 20hz to 200kHz (though you can't hear over 20kHz unless you're a dog).

    The bit rate/sampling rate is not a measure of frequency range.

    You should post what you wrote to me about using PayPal to order if you are an international customer. The website might put some people off from UK or other parts of the world.

    We had the pleasure of hearing the HA-2 during CES in January, and both of us thought it a superb unit. The leather covering reminds me of a vintage Jaguar, feels great, isn't flashy, but secure and luxurious. The controls were solid and well-machined, and we listened to the upcoming PM-3's with it. Even with AAC files on an iPhone6+, the difference between the iPhones audio section and the HA-2 was instantly discernible, with dynamics, texture, and soundstage all significantly improved. 
     
    When we heard the HA-2 attached to a MacBook Pro with lossless and high-res audio, the PM-3s really kicked into gear. We only had a short time, so a longer review will be forthcoming, but compared to other units I've tried, the HA-2 seemed a serious contender. The build quality was really interesting, with a bit of a vintage feel, yet housing serious firepower. I think that the PM-3 (very portable), and the and HA-2 is going to quickly become a portable dream team for many folks. We worked with final, pre-production models, so looking forward to the actual production run units.

    I'm very pleased by what Oppo have done. Got a by ch of pretty pictures of it plus a few words of praise (and caution) up here.

    EDIT: I can't believe it costs 300$. Way too much machine for that.

    Can't wait. This one is definitely in my radar.

    Geez, just what I need...another portable audio gizmo.  LMAO....I'll probably get one once available through Amazon/B&H Photo.

    damn that price [​IMG] even FiiO can't compete entirely, especially design.

    This may sound stupid, but if I attach my OPPO phone to this amp with those rubber bands, will that interfere with the touch screen interface permanently? Like how can you select songs if they are touching the screen?
