Is there a BETA of the new firmware? Looks different

I have purchased the Samsung the EVO Plus 256GB microSD card and can confirm it operates without issue on the M2. The idea that Lexar cards sound "slightly better" without offering any data that quantitatively and qualitively describes this claim and making it open to scrutiny is pretty...

They are currently beta testing a newer version of the M2 firmware v2.5.2 https://www.facebook.com/acousticresearchdigital/posts/1206527589365244 Another review here: http://www.techradar.com/au/reviews/audio-visual/hi-fi-and-audio/audio-systems/acoustic-research-m2-1315598/review?src=rss&attr=all

I can too confirm that the M2 is now truly gapless with the V2.5.1.0 firmware. There is an audible "pop" sound that comes along about a second before the track change when playing 2822.4kHz/1bit DSF files. I have not noticed this with 192kHz/24bit FLAC files or with 44.1kHz/16 bit FLAC.  ...

Any release notes on the new M2 firmware? Will it have 200GB card compatibility? Can you go back to the previous firmware after updating? Will it introduce a high gain / low gain setting and if so will the sound change for big cans whilst catering for IEM's? Are there plans for further...

I've got some feedback regarding using the SanDisk Ultra microSDXC UHS-I Card Premium Edition 200 GB card with this player. Got this on Cyber Monday for ~US$100. Now straight off the bat this card did not play nice, not sure because it's formatted as exFAT and whether Jelly Bean 4.3 has issues...

A few days with now with my new Acoustic Research AR-M2 paired with the Audeze LCD-3s and what impresses is:   *the clarity and space between instruments and vocals *the lack of distortion and lack of coloration *the amplification for a portable device (at full volume on 99% of tracks it is...

Apologies if I'm going to sound like a cliched noob but I don't post often and I just bought  the LCD3 (serial 2615XXX's) and they are worth every cent.   I've had the LCD2 R1's for a couple of years now, they are late revision 1's just before the R2's came out, so I thought I had a reasonable...

Quote:     Yeah I agree with this post. I just bought the Z623 after short-listening tests in-store. All the desktop / ipod dock speakers I listened to sounded very hi-fi, from terrible to tolerable. What in the world is going on with the Monster Beats by Dr Dre beatbox? They should...

  Quote:   That's funny, the Siemens CCa's on my Lyr sound pretty much the same as the stock JJ's, I guess I need to listen to some more money.

Quote:   Perhaps, but you're not gaining a directly proportional $1000 worth of value either, so hyperbole needs to be kept in check. This is especially evident with Leica which I also find proponents being especially guilty of (and I'm an avid owner)   Quote: It's refreshing...

Revealing measurements, but also illustrative to what amounts to quite a sample variation with the LCD2's and the implications for version 3? I hope you get to test another 3.   Perhaps some of us are what you might call "Beta testers" to a point when it comes to this headphone line, but I'd...

Quote:   If anything the dynamics I've listened to have some smaller, fist-like and for lack of a better word, deformed space, performing in such as manner as to ask for your attention not unlike a jester.   The LCD2 sound is all about drawing you irresistibly into a place to...

Quote:   Can you please qualitatively and quantitatively provide us with a description of what "far ahead" means please?     Far ahead in price yes, and unless you provide further information, far ahead in defensive rhetoric as well...  

I pre-ordered 6th of Feb and nothing either. I didn't realise a phone call would push me further behind.
