Whereas TVs have develop into higher and higher over the previous 15 years, audio has taken a number of steps backwards. Many people have sacrificed constancy in pursuit of comfort and portability, adopting inferior audio codecs equivalent to MP3 and making them our new benchmarks. Lossy codecs equivalent to that strip music of its dynamics, element, and vitality. Nevertheless it doesn’t must be that means. Decide up a high-resolution digital audio participant (DAP) and you may have your cake and eat it, too.

Not like old-school MP3 gamers, Apple’s iPod contact, or the everyday smartphone, high-res DAPs are designed with high-end audio circuitry, high-powered digital-to-analog converters (DACs), and amplifiers that may drive a variety of audiophile-class headphones. Their unique goal is to play music, and whereas they will play nearly any kind of music file, they’re actually designed for the codecs and codecs that ship better-than-CD high quality.

Greatest high-res digital audio participant

The most recent addition to Astell&Kern’s KANN line is an impeccable participant that may ship mind-blowing sonic performances with nearly any supply and any kind of headphone, regardless of how troublesome it is likely to be to drive. Desire wired performances? The KANN Alpha is outfitted with 3.5mm unbalanced, 2.2mm balanced, and 4.4mm balanced headphone outputs. Demand the comfort of wi-fi audio? You’ll discover assist for each the LDAP and aptX HD codecs onboard. Yeah, it’s a bit expensive at $1,099, nevertheless it’s value it in the event you demand the perfect.

Appears prefer it’s one other one-two end for Astell&Kern. The SA700 lacks the 4.4mm balanced headphone output that the KANN Alpha boasts, nevertheless it does have a 2.2mm balanced headphone out. And whilst you gained’t get LDAP assist for wi-fi playback, you do get aptX HD assist. Most significantly, the SA700 sounds virtually as implausible.

Greatest budget-priced high-res digital audio participant

You possibly can pay a complete lot extra for a high-resolution digital audio participant, however this mannequin from Activo delivers virtually all the pieces you’ll get in a significantly dearer mannequin for simply $299, together with MQA and aptX HD assist.

How we examined

We state which headphones had been used to overview every participant, however our standbys embody the Bowers & Wilkins’ P7, B&W P5 Wireless, and B&W C5 (Sequence 2) headphones in a wide range of listening environments. 

B&W P7 headphones Bowers & Wilkins

We used Bowers & Wilkins’ P7 over-the-ear headphones for our vital listening exams.

We copied a group of high-res ALAC, FLAC, and DSD music information to 64GB microSD playing cards and used them with all three gamers. Take a look at information had been encoded with 24-bit decision at sampling charges starting from 48- to 192kHz. Among the music information we used had been provided by the producers; others had been bought from HDTracks, B&W’s Society of Sound, AcousticSounds, and related high-res music-download websites. We additionally bought a number of the similar albums on CD and from the iTunes retailer (the latter as lossy AAC-encoded information) for comparability.

Options to search for once you store

Deciding on a high-res DAP might be daunting. They arrive in all shapes, sizes, and value factors. I’ve outlined some function it’s best to look out for.

FLAC and DSD

Together with ALAC, FLAC and DSD are two of the extra well-liked lossless audio codecs you’ll see for high-res music.

Audio codec assist: This spec is necessary. You want lossless, high-res music information to take full benefit of a high-res DAP. We suggest that you simply search for a participant that helps, at a minimal, ALAC, DSD, and FLAC information since these are the commonest codecs that high-resolution obtain websites use. These are the commonest audio codecs you’ll encounter (in alphabetical order):

  • AAC (Superior Audio Coding) A lossy codec generally utilized by iOS gadgets and on the iTunes retailer)
  • ALAC (Apple Lossless Audio Codec) Generally utilized by iOS gadgets
  • APE A free and really environment friendly lossless codec from Monkey’s Audio
  • AptX A near-CD-quality audio codec supported by some Bluetooth gadgets
  • DSD (Direct Stream Digital) A high-resolution codec that originated with SACD (Tremendous Audio CD)
  • FLAC (Free Lossless Audio Codec) A typical free lossless codec
  • MQA (Grasp High quality Authenticated) A backward-compatible lossless codec that applies a digital fingerprint to a file to ensure it was sourced from the unique grasp recording
  • MP3 (MPEG audio layer 3) A quite common lossy codec
  • Ogg-Vorbis A lossy codec that’s well-liked, however much less frequent than MP3
  • WMA (Home windows Media Audio) A lossy codec generally utilized by Home windows gadgets
  • WMAL (WMA Lossless) a lossless codec generally utilized by Home windows gadgets

Consumer interface: Except for bodily traits, variations between consumer interfaces might be dramatic, they usually could make or break your total expertise. Some gamers are based mostly on the Android working system and will likely be very acquainted to Android smartphone customers. Different gamers have proprietary consumer interfaces with a touchscreen, a click on wheel, or navigation buttons. The participant’s consumer interface can affect what you’ll be able to and might’t do on the participant (equivalent to searches) and the way simply you’ll be able to carry out sure duties (equivalent to creating playlists).

Excessive-res DAPs have enormous variations in consumer interfaces. Pioneer’s Android-based UI is our favourite.

Font sizes and legibility range tremendously among the many completely different DAPs, and a few don’t you to regulate the font sizes. In case you have bother studying small font sizes, then it’s best to take into account a mannequin that runs the Android OS, which can present font-sizing choices and different accessibility choices.

Quantity button location: The placement and measurement of the quantity controls are surprisingly necessary. The placement of the quantity button can decide whether or not or not you should utilize a participant with one hand.

Transferring songs: Copying songs to exterior microSD playing cards is drag-and-drop easy, however the best way a DAP handles copying music information to its inner storage varies from one DAP to the subsequent. Some gamers, just like the Pioneer XDP-100R, will mount in your laptop like a tough drive, so you’ll be able to drag-and-drop copy; others require software program on the host laptop (and in some circumstances, that software program is likely to be accessible just for Home windows). Test the specs rigorously.

The Questyle QP1R’s quantity management is on its distinctive crown dial.

Storage capability: Excessive-res DAPs have each inner storage and expandable storage by way of microSD card slots. As a result of high-res music information are considerably bigger than MP3s or iTunes AAC-encoded information, we suggest having a minimal inner storage of 32GB and no less than one—ideally two—microSD slots.

DAC (digital-to-analog converter): The DAC is without doubt one of the most necessary components in a digital audio participant’s design. That is the {hardware} that converts a digital sign into an analog sign which you can hear by headphones or loudspeakers related to an amplifier. Some DAPs also can function a high-end USB DAC to your laptop, conserving the sign within the digital area till it emerges from the noisy setting inside your laptop.

Two specs measure a DAC’s capabilities: Decision (expressed in bits) and sampling charge (expressed in hundreds of cycles per second and notated as kHz). We suggest that you simply search for gamers whose DACs assist no less than 24-bit/192kHz, which can allow it to decode a digital sign encoded with as much as 24 bits of decision at a most sampling charge of 192kHz. Word that these specs measure conversion functionality, not essentially the high quality of the ensuing conversion.

SanDisc MicroSD card SanDisK

Most high-res digital audio gamers will assist microSD playing cards as much as 200GB.  You’ll want to use high-quality, name-brand playing cards.

Native DSD playback: DSD is the digital audio format utilized by SACDs. Many high-res DAPs assist DSD, however not all do. And never all gamers deal with DSD information in the identical means.

Most gamers convert DSD into PCM (Pulse Code Modulation) for playback. Some folks object to the notion of changing DSD to PCM. For those who share this concern, then search for a participant that performs DSD information natively.  Whether or not or not you’ll be able to hear a distinction between the native DSD file or the transformed PCM is past the scope of this roundup.

Bluetooth: Not all high-res gamers include Bluetooth. For those who plan on utilizing Bluetooth wi-fi headphones along with your digital audio participant, we suggest that the participant helps aptX, which guarantees close to CD-quality wi-fi playback. Some newer DAPs additionally assist aptX HD, which allows the participant to stream digital audio information with 24-bit decision and sampling charges as excessive as 48kHz (i.e., better-than-CD high quality). With each codecs, the participant and the headphones you pair with them should be able to supporting the codec.

aptx codec aptX

Some high-res gamers assist Bluetooth streaming and others don’t. You’ll get the perfect Bluetooth expertise with tools that additionally helps the aptX codec, which delivers near-CD-quality audio.

Streaming providers: If you wish to entry streaming providers equivalent to Tidal (certainly one of few that stream FLAC and that additionally helps MQA information), take word: Not all high-res DAPs are outfitted with Wi-Fi adapters, and even fewer have integration with streaming providers. If streaming providers are necessary to you, be sure you purchase a DAP that may connect with Wi-Fi networks.

Distant management: Many (if not most) of immediately’s high-resolution DAPs include their very own analog-style quantity controls. Consequently, most DAP’s don’t work with in-line headphone distant controls. If this function is necessary to you, then examine the producer’s specs rigorously.

Hello-Res Audio brand: Some DAPs bear the Hello-Res Audio consortium’s brand. A DAP bearing this brand doesn’t essentially imply that it outperforms than one with out the emblem, it simply implies that its producer has paid a licensing payment and has agreed to follow a set of product guidelines and performance requirements.

Some DAPs will bear the Hello-Res Audio brand. This certification signifies that the participant meets a set of minimal specs for enjoying again high-res music information.

What do you must expertise high-res music?

John Siau, Vice President of Benchmark Media Techniques, wrote an excellent summary of what high-res music is—and is not.  It’s a terrific introduction to the subject. For sure, in an effort to expertise the audible advantages of high-resolution music, you want a high-quality element at each stage of the sign path. For the needs of this dialogue, which means music recorded, mastered, and encoded in high-res; a digital audio participant—the DAC and amplifier components—that helps high-res playback; and headphones able to reproducing high-res music. Your playback will solely be nearly as good because the weakest hyperlink in your system.

Headphones: When you would possibly get pleasure from your Apple earbuds for strolling down the road, they gained’t ship the complete advantage of high-res music performed by a high-res DAP. You’ll need to spend money on a high-quality pair of headphones—ideally the over the ear kind—which have bigger drivers, better dynamics, and the additional advantage of decreasing the noise flooring as you hear. Excessive-quality headphones might be discovered for just a few hundred {dollars}, with premium audiophile fashions simply costing greater than $1000.

Whereas most music lovers can’t afford Sennheiser’s $1699 HD 800 S headphones, you do need to use the very best quality headphones you’ll be able to afford with a high-res digital audio participant. That seemingly means spending just a few hundred {dollars}.

Excessive-res music-download websites: The tracks you’ve ripped from CD should not excessive decision, and also you gained’t discover high-res music information on the iTunes, Amazon MP3, or Google Play shops, both retailer both—no less than not but. Upconverting these music information gained’t magically rework them into high-resolution tracks, both—you’ll be able to’t put in what was by no means there within the first place. Your finest sources for buying high-res music information are on-line shops equivalent to HDTracks.com, B&W Society of Sound, Linn Records, AcousticSounds.com, or iTrax.com. However purchaser beware: Some websites classify tracks as high-res regardless that they had been recorded and mastered at solely CD high quality (16-bit/44.1kHz).

Can you actually hear the distinction?

Now that’s the large query isn’t it? Are you able to actually hear the distinction? Learn very rigorously, as many producers will declare one thing to the impact that their high-res music participant “reveals extra of the unique musical efficiency than an MP3 participant or sensible cellphones.”  Saying high-res is best than MP3 is not any higher than saying a CD is best than an MP3 file.  In fact it’s, however many can’t hear the distinction between an MP3 file and a CD (or a high-resolution observe for that matter). Suppose you’ll be able to? Try this online test from NPR.org (be sure you hear on the best-quality headphones or speaker system you have got).  

Think you can tell the difference between MP3 files and uncompressed WAV files?  Take this test on N NPR

Suppose you’ll be able to inform the distinction between MP3 information and uncompressed WAV information?  Take this test at NPR.org to search out out.

Now issues get muddier in the case of the variations between CDs and high-resolution music information (you can download CD-quality and high-res files as part of this experiment conducted by Scott Wilkinson and Dr. Mark Waldrep on AVS Forum to see if you can tell the difference).  That’s why you’ll oftentimes see producers (and even high-resolution music websites) examine their stuff to MP3. So what’s the underside line right here? Correctly recorded and mastered high-res music is the true deal, however don’t be stunned in the event you or your pals typically can’t inform the distinction between CD and high-res tracks.

Hello-res audio, high-res music: Not the identical factor

Lastly, we’ll open this may of worms ever so barely. Hello-Res Audio and high-resolution music should not the identical factor. Hello-Res Audio is a correct noun defining playback {hardware}, whereas high-resolution music refers back to the precise music information. The 2 phrases are typically used interchangeably, sowing confusion. What’s extra, the time period “high-res” hasn’t been usefully outlined (see Bob Stuart’s article from the Journal of the Audio Engineering Society, “Excessive-Decision Audio A persepctive.”

(An article written by Bob Stuart for the Journal of the Audio Engineering Society.)

 

On the danger of oversimplifying the main points, simply know that “excessive decision” is being outlined by the audio business as something exceeding CD high quality. For a lot of, that definition merely isn’t ok. If that’s you and also you need to study extra about a number of the points surrounding high-resolution recording and playback, try the Real HD-Audio blog by Dr. Mark Waldrep of AIX Data.  Comfortable listening.
