    4 Stars
    Nice sounding little powerhouse for close range or small room listening.
    First off the Bluetooth makes noise as soon as you connect. You can't hear it during playback but it's raising the noise floor nonetheless.This is a flexible integrated that serves well as a DAC/tube preamp in my system currently.Rolling tubes brings some interesting results. I have yet to find a preference. I have also yet to hear a bad combination.The power is a bit weak in this one so I immediately opted for the Aiyima A07 stereo amplifier with 48 volt 5 amp power supply. That made all the difference.Don't listen to anybody else. Trust your ears. Screw what other people think. If it sounds good to you it sounds good.Use good speaker wires for a big upgrade. I am using Mapleshade Golden Helix in 8 ft length. I'm also using Mapleshade biwire jumpers on my Energy C2 speakers. The wires cost more than the speakers and amp/preamp combined. The nice thing is that you can bring wires along for the journey. I swear by everything Mapleshade. They have never let me down.

    5.0 out of 5 stars What a fantastic little amp
    Reviewed in the United States on June 22, 2022
    After much fan fare, great reviews (cheap audio man etc.) and waiting for it to finally come back in stock, I have to say I’m super pleased with this little beast. I have it hooked up to my Klipsch RP600M, Apple AirPort express via optical for Airplay2, and my turntable via Fosi Audio Box X2 preamp to the RCA inputs. I also have my Klipsch powered sub attached via the Aux out. The majority of my listening has been done via Apple Music through the optical/DAC. Right off bat, the sound is fantastic. The sound stage impressive for an amp this price, and once I had the tone controls dialed in (two pips down on the bass, three up on the treble for me!) the tone and texture are equally good. The tubes really do add a touch of warmth and soften the digital input (I’m looking forward to doing some tube rolling too). The Airplay is so good I’ve not even tried the the Bluetooth. One notable thing that should be mentioned is the power saving click. When the amp loses signal for 10 seconds in any input, there is an audible ‘click’. This can be off putting at first, but as I understand it, it’s a mechanism to prolong the life of the box. After a while I don’t even notice it, just know that it’s not the unit being defective, it’s by design. Oh and it’s even got a remote! Pretty basic, but does the job. Over all I can’t sing the praises high enough for this little amp, it offers fantastic bang for the buck and even looks super cool. The VU meter is a nice touch, though I never listen loud enough to get it jumping much!

    5.0 out of 5 stars Nice little amp
    Reviewed in the United States on May 7, 2023
    I'm pretty impressed with this little amp. The sound from such a small box is quite impressive, just good clean audio. I spent a day so far tinkering with fine tuning sound etc, and all functions seem to work well. No high pitch noises or squealing like you get with some of the lesser known amplifiers. Aiyima just puts out solid products and this little guy is one of 'em.

    With all this said I do believe this amp will work best in a nearfield application, such as a desktop setting. It is definitely a nice little amp, but I think it'd be unfair to expect it to run power hungry speakers and sound like a 5oo dollar reciever. However I did use the stock 24 volt ac adapter so upgrading
    to a higher rated adapter is prolly the best way to go if trying to push a large set of speakers.
    All in all I'm pleased with the product and feel most others will be too.

    This is my honest take of the Aiyima t9 amplifier.

    デスクトップPCのオーディオ用には最適かなと思います。

    ただ、全ての端子が背面に付いているので、ケーブルが短い機器は延長しないと接続しにくいかなと思いました。
    それを差し引いても高評価を付けたい商品です。

    BASSとTREBLEを調節するツマミがあるのもすごいいい所だと思います。

    5.0 out of 5 stars Amazing sound!
    Reviewed in Australia on September 3, 2022
    I bought this little thing to use as a desktop amp for my Emotiva B1+ speakers that I am waiting to arrive. I couldn't resist trying it in my main system so I hooked it up to my JBL towers and connected my Allo streamer through the coax input and I was totally surprised by how well they sounded. Well defined and strong bass, airy treble and wide soundstage. The most surprising was the soundstage that was the same size as my Audiolab 8300A amplifier. The lacking was in the lower midrange and upper bass so it sounded hollow and muddy, especially with bad recordings of 70's and 80's rock'n'roll (still very well for the money). But then, the real surprise came when I actually fed it through RCA input with my ARES II DAC as a source. OMG, it sounds almost as good as my $2000 amp. It quickly deteriorates if I play it above 70dB but at medium power listening, it is almost too good to be true. A warm but well-defined and spacious sound that is very musical. It's a joy to listen to.
    I had none of the problems that some people experienced with it, clicking is there but only when you turn it on, not important. Also, the remote works well for me, with no interference to other gear. We will see how reliable this little amp is but if you are going to use it as a pure amp you will be amazed and have a lot of fun.
    B.

    Update: I paired T9 with iFi Audio DAC V2 and Emotiva B1+ speakers and completed my desktop setup. Sounds detailed, with a wide sound stage and smooth midrange, controlled bass. After spending a month with this little amp I can only tell that it is worth every dollar and more. I haven't had any of the known issues, everything works smoothly.
