AIYIMA T1 PRO Tube Preamp Vacuum Receiver Home Audio Preamplifier with RCA/Bluetooth & Bass Treble for HiFi Stereo Amplifier&Powered Speakers,with AUX/12V Trigger Signal Output

Aiyima’s T2 preamplifier appears to be well-built and is surprisingly compact. The volume and tone nobs feel positive, with palpable clicks indicating adjustments. The included RCA cable is of very good quality. The tubes installed easily, I did have to make a slight adjustment to some of the pins. Just take your time, make sure the pins are straight, and avoid forcing anything. This unit pairs nicely with my Aiyima A07 amplifier, adding tone controls and Bluetooth connectivity to my system. Not to mention the customizable tube sound (the tubes can be swapped to achieve different sound signatures). I look forward to testing out a few different tubes in the future. Turning on the unit gives off a nice blue glow from the tubes, with hints of an amber bulb color as the tubes warm up. The Bluetooth connected with ease, the Aiyima name popped up immediately on my Android phone and quickly connected. The tone controls offer plenty of adjustment. I can now make quick changes as I jump from one music genre to the next. The T2 comes with two sets of pre-outs, allowing you to connect a second amplifier if desired. Overall if you’re looking to add tube-sound, tone controls, and Bluetooth connectivity, this is what you’re after. My setup: I'm using the internal DAC from an MSI B150i Gaming Pro, connected via 3.5mm aux to RCA adapter to the Aiyima T2 preamplifier. From the Aiyima T2 preamplifier I’m connected to an Aiyima A07. Then from the Aiyima A07 out to a pair of JBL A130 bookshelf speakers and an Emotiva Airmotiv SE8 subwoofer.

Great soundstage, quality volume and tone controls. Stable BT connection. I built some Paul Carmody Speedster bookshelf speakers and a Voxel passive sub. Power my bookshelves with with an SMSL SA-98E (about 50 watts per channel (though they advertised at 100wpc) and a Dayton 2.1 t-amp (where the 2 channel amp is left unused. Findings: The speedsters are power hungry so my SMSL SA-50 didn’t have enough juice to push them. I tried the Dayton amp as a stand-alone 2.1 desktop setup. But found the 2-channel soundstage really compressed and flat. I tried the Fosi 2.1 amp and it was even worse. Read, I plugged it in and immediately opened a return request back to Amazon. It was complete garbage. So I limped along with a cheap Logitech BT adapter and fed the two outputs to the two amps and controlled the volume separately… it was ‘fine’. Sounds was OK but still compressed. So I decided a tube preamp may help. Obviously the dual output would solve the two volume controls, but was going for a better soundstage. Delivered in spades! Wide open staging, clear imaging, clean sound. I’m coming from a mid-fi background. Never paid more than $1000 per speaker (think Martin Logan and B&W) and there’s a lot of snake oil out there. This pre-amp is the real deal. I’m not super picky anymore, but know what decent sound should sound like. This fits the bill.

I didnt want to write my review until i had spent some serious time listening and comparing and felt like i really had a handle on what it does to the sound. Starting off, i paired this up with my klipsch r41m speakers. At first listen, i couldnt tell much difference compared to baseline with just my amp. After a while, i realized that the tubes actually had a slight effect on bass delivery, the bass was slightly louder and more full. There was no discernable difference in the fidelity of the music. What really surprised me was that it actually sounded fine whether i played classic rock, bassy pop music, or something quick and technical and very bass heavy like glitch mob. Nobody talks about the fact that tubes also pair nicely with modern music. The other thing i noticed is that while i couldnt put it into words, i felt more drawn to listen to music more often and for longer with the tubes. Fast forward to week 2, and I installed a pair of Lm4562 op amps, and a meanwell switching power supply. I wont pretend either makes any noticeable difference, i simply did it because i could, and for the assurance that i would have the lowest possible amounts of distortion and noise coming out of this device. Now, my JBL a130s come in the mail. Holy BATMAN what an amazing speaker. For the first time in my life i learn that cymbals and guitar strings actually make a sound, not just a note. All kinds of new things in my music! Ok, now its time to add the tubes. Right away now i can hear a difference in the music. That new found detail and "sparkle" in the high frequency is slightly dampened , and replaced with a touch of warmth and a bit of a rolloff of high frequency spl. Still sounds amazing with all music types. Another test I did was to set my system at listening volume with music paused and compare noise floor levels of just the amp, vs tube turned up to full volume vs tube turned all the way down. There is NO discernable difference in noise floor regardless of what you do with this preamp. Im honestly amazed at how silent this thing is. If you are looking for something "tubby" and "soft" sounding, with a bit of crackle and hum this is not it. If you are looking for an aptx hd bluetooth preamp that will maintain music fidelity and add a TOUCH of tube warmth to your music then this is the product for you. I am honestly quite pleased with it and it will become a permanent part of my system for all music types, and i seriously listen to a bit of everything. This is a hands down 5 star recommendation from me

息子のオーディオ向けに、パワーアンプのA07Max 2台と共に、 プライムセールで実勢価格11000円強で購入。 このプリアンプ、ハイエンドオーディオよりも音が良かったです。 トーンコントロールも増強、減衰がハイエンドオーディオ製品の様な音質バランス。 真空管特有の甘美な音質が乗りつつ、鮮度の高い音が出たのは素晴らしいと思いました。 全体的な音質は、透明度が深く、奥行感、拡がりも申し分無い。 トリガーアウトが付いているので、対応パワーアンプならば電源連動出来るという便利な機能まである。 AUX INがあるが、この部分を使用するとボリュームコントロールが無効になる事には注意です。 また、内蔵されているBluetoothは半分オマケで若干高調波ノイズが混じり気味で本格使用には向かないと思います。 間に合わせで使用する分にはよいかと。 当方では別に用意していたAPTX対応のBluetoothレシーバーの方が音に厚みがありましたので、そちらを接続しています。 個人的には、Bluetoothレシーバー部とAUX入力を削って、2系統ライン入力が可能なものか同一デザインのライン入力セレクターが発売されたら申し分無いなと思います。 星5個は、機能よりも音質に感動して、この評価です。

Pus si se nota un cambio ligero en el sonido, es un poco más suave y menos áspero, en mi caso lo puse al final de una cadena de procesadores para reducir el efecto metálico digital de los mismos.

J'ai acheté l'ensemble de la vidéo en plusieurs fois, très content du son et je suis un peu difficile, tout est très bien emballé, pas de casse, je vous recommande, j'écoute sur Qobuz avec le dac en USB sur des enceintes Kef.

Excellent reproduction of streamed music.

Fast and clean interface. Sounds great!
