Introducing the hottest high -resolution players at a stretch, such as dual DAC and balance correspondence for 50,000 yen or less --Av Watch

　A portable player that often has two "cars" with a smartphone.With a product of 20,000 yen for 20,000 yen, it is noteworthy of Sony's thin Sony "Walkman A" (NW-A20), which is less likely to get in the way even with these two cars, and the palm-sized COWON "PLENUE D".

　Neither supports DSD playback, but PCM supports 192kHz/24bit.With plenue D, you can feel the step -up from your smartphone in terms of functions, such as the abundant equalizer, and the noise cancellation function in Walkman A.

　In the 40,000 yen and 50,000 yen players, there are many products that have more individuality and are particular about the sound quality.Attention points are DSD.The DSD distribution of high -resolution songs has also increased, so I want a DSD playback -compatible player, but there are two types of main divisions even if it can be played in a bite.One is a "native playback" of the DSD data as it is, and the other is "PCM conversion playback" that converts DSD to PCM due to mounted DAC or processing capacity issues.Both can be played, but "native playback" is desirable to enjoy the goodness of DSD as it is.

　Until now, this native playback was a monopoly patent for luxury players, but a model of 40,000 yen and 50,000 yen has begun to appear.

　What is worrisome about the basic specifications of the player is the built -in memory capacity.Although the capacity is often small in low -priced models, it has a microSD card slot and the number of models that can extend the memory is increasing, so it is not very bothered.Some models have two slots.

　マニアックな点としては、バランス出力も見逃せない。対応するケーブル&イヤフォンを用意すれば、通常のステレオミニ出力より、チャンネルセパレーションや駆動力に優れた再生が楽しめる。今現在、バランス駆動対応のイヤフォン/ヘッドフォン/ケーブルを持っていなかったとしても、将来的なステップアップを考慮し、対応したプレーヤーを選ぶのもアリだろう。

　Speaking of step -ups, I want to be careful about whether there is digital output.There are models with optical digital outputs, and some models that can use USB audio digital output, such as smartphones, can be combined with a portable amplifier with a built -in DAC if you are dissatisfied with the sound quality.

　これらの特徴を備えた注目はAstell&Kern「AK70」。DSDはPCMへの変換再生だが、バランス出力やUSBデジタルオーディオ出力にも対応。Luxury & precision「L3」は、デュアルDACを備え、DSDネイティブ再生対応。バランス出力も備えた多機能さながら、49,800円に抑えている。
