MAKTARSpectra X2 Portable DAC AMP (USB-C) | High Resolution 32bit / 384kHz DAC | Headphone Amplifier Compatible for iPhone 15, iPad, MacBook, Android | USB DAC Amp for PC | Portable Headphone Amp

I have only had this device for a few days and have yet to take it through it’s paces with my tougher to drive headphones. So far, I’ve logged a lot of time on the Westone W80. These IEMs are really efficient and sound surprising acceptable connected to the basic iPhone DAC cable; they are absolutely stunning running through the X2.The design is simple, smaller than a fountain pen and built rock solid.I’ll spare you the audiophile jargon and simply say if you listen to Hi-Res audio through an iOS device you cannot go wrong with the Maktar Spectra X2.While the X2 is nearly perfect, my only grip is that a device with this form factor and at this price point should really have an app to dial in the EQ.That said, I am extremely pleased with my purchase.EDIT: I tried this device with my HD 650. These headphones are notoriously power hungry. While the sound was clean there just wasn’t enough power to drive them. If you are expecting to use the X2 to push 300Ω, you are going to have a bad time.The description says as much. Not the reason I purchased this. My 5 star rating still applies.EDIT 2: A month in, I love this more than ever. I bought a right angle lightning adapter as I was afraid the attached cable may eventually fray and wear out. There was no evidence that this was the case but it was giving me anxiety.I’ve output the X2 to my primary desktop headphone amp. Pure audible bliss with the HD 650.My greatest fear now is that Apple will replace the lightning port on their phones.

First, I received product on time and in new condition. It works as it should - plug in the ends and you hear high quality audio.Part of the cost must surely have gone to the packaging as its high quality. Gives you that premium feeling.Is it worth the price?Not sure. I'm happy with it but I do suggest price shopping if budget is a concern.

After getting a few notes from audiophiles, I revised this review.---The $10 JSAUX dongle I was using before does just as good a job as this $170 Spectra X2 dongle. They both claim the DAC is good for up to 32bit/384kHz, and they sound the same.Spectra X2 claims to be an amplifier, but it doesn't power my 20 Ohm impedance headphones (HifiMan Sundara-C) any better than the cheapo dongle. Volume levels are exactly the same with or without the Spectra X2, across 3 different devices I used it on. The amp part must be super weak.The only reason to even mention amplification in the title must be for SEO/clickbait nonsense.---Furthermore, Amazon sent me a very Used scratched up one despite having ordered it New. It must be wrecked to offer such lousy performance. Instead of letting me throw it away and get a replacement, they want me to waste my day at the post office to return this junk first.Horrible experience overall.

Very happy with the sound, better if you use Qobuz or Tidal to enjoy full range

I would much rather have the power of the Spectra X than the great soundstage of the X2. Disappointed they reduced the power by a lot. Maybe it has to do with apples Mfi program but so not sure. All I know is that i would rather hook the X to a stupid apple camera adapter and then hook it to my iphone than to have this weak sound come out. The spectra X actually feels like a I have a mini amplifier with me. Not as convenient but its also $50 cheaper now.The spectra x is also more versatile since its USB instead of lightning.X2= great soundstage, weaker soundX= more power, versatility, cheaper...

Works as advertised. Allows my iPhone to play at higher resolution than possible with the normal lightning to mini adapters. Sound profile and soundstage are noticeably improved (depending on quality of recorded music). Only downside is the controls on my headphones don’t seem to operate when plugged into this adapter. Not really a big deal for me but thought I should mention it.

As someone with high end gear: TA-ZH1ES ($2000), Sony Z1r ($1500), this device surprised me with it's quality.Nice bass and solid build quality. I don't have any lossless media on my iphone 8 plus, but even youtube sounds great.

Looks great but I'm not sure if it's even working- there's nothing to tell you the difference- no switching anything on- just plug and play and since I use Sennheiser IE 300 with it- the headphones already play Hi Res Audio so idk- may end up returning it- bought it to use with my Sennheiser HD660 over ears but I don't hear any difference at all. And those HD660 sound pretty awful for something over 600 bucks although I got them at the Black Friday price. So to anyone in doubt- maybe shop around for something different where you can hear and see the difference.

I bought this at the end of 2023, but only started actively using it in April 2024. Absolute garbage. Stopped working this week, starting the 20th of May 2024. Unfortunately, it is no longer possible for me to return the item. Very disappointed. Seriously, do not buy this.

再生音質はクリアで奥行きがあり透き通った中高音が出ます。低音は少し物足りない。音質としては個性として受け取れるけど曲間に結構大きめのポップノイズがあります。この値段のDACでノイズ対策してないのか、という感じ。素晴らしい音質の曲間に入る無粋なポップノイズ。どうにも気になって仕方なく音楽に集中できません。

iPodTouch（第７世代）を外付けdacで聴いてみたかったので本機を購入しました。ipodの再生アプリはラディウスのNeplayerのlite版をダウンロードして課金してして使っています。音楽ファイルはFLACファイル（16bit,44.1kHz～24bit,96kHz）のみ再生して聴いています。巷では、iPodやiPhoneは音がのっぺりしてイマイチ、Hi-Fiではない，音質ならソニーのウォークマンの勝ちというレビューばかり見かけますが、iPodの音はフラットで聴いていて疲れません。私の中では，ウォークマンがCDの音なら，iPodはアナログレコードやカセットテープの音です。本機 Spectra X2を繋げて聴くと、音はさらにクリアになり、音質に磨きがかかります。長い間ウォークマンを使っていましたが、もう戻ることはないでしょう。ちなみに，本機は商品名にヘッドホンアンプと書いてありますが，dacです。音量の調節機能はありませんのでご注意ください（ipod本体で音量を調整）。また，「携帯」という過酷な環境では，ライトニング接続は不利なようで，頻繁な操作や出し入れをするとipodと本機が接触不良を起こし，プレイが中断します。そのため，お気に入りのアルバムをじっくり聴くときにだけ接続し，そうでないときは，ipod本体にイヤホン直挿しで聴いています。最後に，ipodと本機を部屋のリスニングシステムにも接続して聴いてみました。音圧は低めですが，音質はとても素晴らしいものでした。iPodでも十分にメインシステムになります。すごい時代になりましたね。

人気があって品薄状態なのでしょうか。随分と待ちました。

軽量コンパクトな本体はとても気に入ったが、肝心な音質がイマイチだった。また、他レビューにも有るように、AppleMusicやAmazonMusicの曲間に「ジリジリ」といったノイズが入る。これは致命的。価格と品質のバランスが取れていないと判断し、返品した。※あくまでも私の主観なので、ご了承ください。
