DAP Acoustic Research offers brawny and energetic bass, musical and smooth midrange as well as free, transparent high notes.<\/p>\n\n\n\n

At the beginning of this year in the \u201cinternet\u201d appeared information about launching a portable player of the Acoustic Research AR-M200. <\/strong>An American company with decades of experience probably associates every self-respecting audiophile. It is true that the AR department dealing with portable devices (apart from DAPs are headphones and accessories) is relatively young, but noblesse oblige, so the opportunity to test the new DAP from this stable I was very pleased.<\/p>\n\n\n\n

Encouraged by opinions on the topic of Acoustic Research portable musicians, I decided to take a look at the current offer of the producer.\u00a0Three \u201cHIFI Media Players\u201d (the term comes from the AR site) is a very modest offer, not to say poor, especially when compared to the offer of Far East brands growing like mushrooms after the rain, which such machines get in a dozen or so paces more, but \u2013 as wise people say \u2013 sometimes less is more.\u00a0Especially since the mobile portfolio of Acoustic Research is well thought out and logically organized.<\/p>\n\n\n\n

At the highest level among DAPs is currently AR-M2 operating on the basis of Android and DAC Burr-Brown PCM1794A. The lower level is occupied by the AR-M20, also with Android on board and Burr-Brown, but now PCM5242. In turn, the AR-M200 described here is \u2013 judging from the seemingly simple \u2013 a real minimalist. Without a green robot, a touch screen and lots of fancy functions. So what, without a revelation? Well, not necessarily. After all, they teach in kindergarten that everything is not golden what is shining.<\/p>\n\n\n\n

Construction and functionality<\/h2>\n\n\n\n

AR-M200 was intended to be the manufacturer of DAP, above all simple to use and functional. Deprived of goodies in the form of a touch screen with UHD resolution that draws the current like horse drops. It turned out that all you need is a 2.4-inch 240\u00d7320 \u201cchapter\u201d. OK, the interface is a bit clumsy by all these cuts, six buttons (home, enter \/ play \/ pause, up and down arrows, \u201c+\u201d and \u201c-\u201d for volume control) are not very intuitive (there is no shortage of space under the display, so they could easily create a circle, for example), and searching resources could be faster.<\/p>\n\n\n\n

\u201cThe sound of DAP Acoustic Research is free from artificiality related to data reconstruction, filtering, or God knows what other binary effects on the audio signal\u201d<\/p><\/blockquote>\n\n\n\n

But there are also surprises.\u00a0And what!\u00a0Above all \u2013 finally!\u00a0\u2013 a type C USB socket instead of a hopeless micro-USB, which hardly ever gets hit the first time.\u00a0For this balanced 4.4mm headphone jack (relatively new Sony Pentaconn standard) next to, of course, the classic mini 3.5mm.\u00a0We also have to enjoy perfect integration with the computer, thanks to which, after connecting the DAP to a PC, the library can be operated eg from Total Commander level, which is very convenient.<\/p>\n\n\n\n

The AR-M200 ergonomics is not too bad either.\u00a0The player is surely in your hand, it is pleasant to touch and light.\u00a0This last feature results from the use of plastic, which (on the front and sides) looks like metal.\u00a0In turn, the backs have a \u201cnon-slip\u201d texture that mimics the skin.\u00a0What is most important from the point of view of a lover of high quality sound is not visible to the naked eye anyway.\u00a0Investors were not invested in the tinsel, but in truly audiophile components, which \u2013 anticipating the continuation of the review \u2013 definitely paid off.\u00a0First of all, a great DAC \u2013 AK4490EQ was used, thanks to which the AR-M200 natively supports 24\/192 files as well as DSD up to 128 (5.6MHz) in DoP mode.\u00a0In addition, Texas Instruments TPA 6120 operational amplifiers were thrown in,\u00a0Burr-Brown OPA 2134 preamplifier and digital potentiometer with half-step step (150 steps).\u00a0The 1700mAh battery allows the DAP AR to work for over 7 hours, despite the use of a headphone amplifier in class A. As the manufacturer emphasizes, this combination \u2013 A class amplifier (2Vrms), capacious battery and high-class components \u2013 allows the M200 to drive virtually any headphones and intrathecal headphones.\u00a0The internal capacity is modest 32GB (28.6GB), but the memory card slot allows it to multiply.\u00a0Positive tests have passed the \u201cflash\u201d SDXC up to 256GB.\u00a0One should only remember that this type of media with a capacity of 64GB and higher, where the exFAT system is used, before inserting into the AR-M200, format it to the FAT32 system.\u00a0The 1700mAh battery allows the DAP AR to work for over 7 hours, despite the use of a headphone amplifier in class A.

\"\"<\/a><\/figure>\n\n\n\n

Let\u2019s go back to functionality for a moment. It is true that there is no Wi-Fi and Tidal service, but there is a Bluetooth module with the support of the aptX codec and \u2013 tadam! \u2013 two-way communication, thanks to which DAP Acoustic Research can receive audio signal from other transmitters, eg a computer, tablet or smartphone, and then send it to connected headphones or, better yet, an amplifier (in the latter case you will need a minijack cable for 2x chinch ). Of course, the AR-M200 can also perform the classic function of an audio signal transmitter for headphones equipped with a Bluetooth receiver (in Music Mode select Music Settings, then Bluetooth Output and Scan \u2013 this is not so obvious, and the quick guide only tells you how configure M200 as Bluetooth Audio Reciver).<\/p>\n\n\n\n

I mentioned the lack of goodies, right? It turns out that this is not exactly the case, because the AR-M200 has a built-in microphone (it is placed on the bottom, next to the sockets). It is useful when you set up the device as Bluetooth Audio Reciver and pair with your smartphone. Incoming calls can then be answered \/ rejected either on the phone or just on M200 (an appropriate message will be displayed on the DAP screen). It is true that I do not fully understand why someone would complicate their life so much, but I assume that in some situations (such as a temporary phone call) this may make sense.<\/p>\n\n\n\n

Sound quality<\/h2>\n\n\n\n

It may sound like a truism, but the AR-M200 is very close to the music.\u00a0First of all, its sound does not bear the typical signs of \u201cdigitization\u201d \u2013 it is free of sharpness, dryness or sterility.\u00a0Focusing on the sounds of instruments is child\u2019s play, the brain does not have to perform additional operations.\u00a0In other words, the sound of DAP Acoustic Research is free from the artificiality associated with data reconstruction, filtering whether God knows what else zeriekdynkowym operations on the audio signal.\u00a0Concentrating on music and experiencing emotions is something obvious in this situation, because nothing in this message needs to be \u201cinterpolated\u201d.<\/p>\n\n\n\n

\"\"<\/a><\/figure>\n\n\n\n

The strength of the AR-M200 is the reproduction of the lowest components. The bass is brawny, energetic, juicy and musical. The double bass is stable, has slightly rounded, though clearly outlined contours that do not soften and blur. The speed, coherence and selectivity of the low components is at a very decent level, as is the ability to express rhythmic accents. The bass guitar in Steven Wilson\u2019s \u201cLuminol\u201d (FLAC 24\/96) on the DAP AR gained \u2013 in comparison with the AK70 MKII described on the neighboring pages \u2013 a slightly warmer color and better spatiality. The player Astell & Kern presented, in turn, a slightly better attack elasticity, accuracy and greater dynamics, and provided information about the articulation with almost surgical precision. AR-M200 is not that uncompromising in this respect,<\/p>\n\n\n\n

The range of the diameter seems \u2013 in comparison with the AK70 MKII \u2013 a bit more matte, but also more musical, more pleasant to receive. It does not prick or irritate, sibilants and micro-details are present, but do not bore into the skull, the message is a bit smoother. I really liked both the sound of the acoustic guitar (\u201cThe Watchmaker\u201d from the album \u201cThe Raven \u2026\u201d by Steven Wilson) \u2013 energetic and clear, out of focus, but spontaneously reflecting the transient sounds, with clear details with a stronger attack and exemplary selectivity \u2013 and vocals \u2013 vivid, close and well saturated, sometimes accentuating hissing sounds (eg Norah Jones \u201cCome Away With Me\u201d), but not enough to talk about \u201cprogrammatic\u201d displaying of sibilants or a characteristic component of color.<\/p>\n\n\n\n

The mountain is characterized by a fairly bright color, but in comparison with the AK70 MKII, it still gives the impression of being calm, i.e. less analytical, devoid of \u201cbile\u201d.\u00a0It can not break records in terms of openness, but it carries a lot of energy, is free and clear enough to attract attention.\u00a0The percussion plates are saturated, they last long and present a wide dynamic range.\u00a0They are also very true, as shown by listening to the perfectly realized \u201cNow This\u201d album by Gary Peacock Trio (FLAC 24\/96).\u00a0With the ATH-AR5BT Audio Tech headphones, hi-hat sounded great \u2013 the contact of the upper sheet with the bottom gave a very authentic effect \u2013 point, short, well-defined and quickly fading \u201cCycle\u201d.<\/p>\n\n\n\n

\"\"<\/a><\/figure>\n\n\n\n

The space created by the AR-M200 is characterized not so much by a precise location as by a large scale, spaciousness and density. The apparent sources are tangible, which results from the approximate scene. Both in smaller recordings (Norah Jones) and in larger instruments (eg Dead Can Dance \u201cAmnesia\u201d), the first plan dominates in the transmission, the impression of closeness is strong and clear. Slightly less convincing results spatial effects on further plans, although this aspect is largely dependent on the headphones connected to the DAP.<\/p>\n\n\n\n

Summary<\/h2>\n\n\n\n

With something like this in your pocket (and on the headphones), you do not think about snapping your fingers on the screen and watching covers in super and ultra resolution. Consent, the AR-M200 interface could be more friendly, but this is not the most important thing. The sound of this DAP \u201cgoes\u201d one time, comprehensively, smoothly and without any \u201cbuts\u201d. For something like that, it\u2019s worth taking up the challenge and becoming even \u2026 a minimalist.<\/p>\n\n\n\n

Verdict: Acoustic Research AR-M200<\/h3>\n\n\n\n
