T1PRO Mini Tube Bluetooth Preamplifier with Treble/Bass Control | QCC3040 APTX-HD,Swappable NE3255P Op-Amp,12V Trigger Output & AUX Out,Vacuum Home HiFi Pre-Amp for Power Amp(AIYIMA A07Max)

I have a pretty simple audio setup connected to my PC, consisting of a 6.1 creative surround sound speaker system for gaming, but also have the output connected to a cheap D class amplifier from Nobsound that cost me all of about £25 and hooked up to that are a pair of Mission M71 bookshelf speakers. For the price I paid, I have been well impressed with that little amplifier, but it doesn’t have any tone controls, so when offered the chance to test this little tube pre-amp, I was keen to give it a go.The T1 Pro is nice and compact at just 13cm x 11.5cm x 3.5cm (WxDxH) and with it’s all metal exterior, it feels really nice and solid.At the front you have 2 metal switches, with one being used to swap between power off, Bluetooth or RCA mode. The other lets you turn on the tone controls or to bypass them completely.You have 3 metal rotary knobs that are used to control bass, treble and volume – these all feel really nice to use with a smooth action that clicks into place as you turn them.On the top are 2 sockets for connecting the included tubes. These simply push into place and when powered on give off a nice blue glow.Around the back is where all of the connections are made, with an RF aerial socket, a reset hole for the Bluetooth connection, a pair of RCA inputs and RCA output, a 3.5mm AUX output, a 3.5mm 12v trigger to automatically switch on an amplifier and a 12v DC power socket.Finally, at the bottom are 4 nice silicone feet to stop the device from skating around your desk.***** In The Box *****1 x T1 Pro2 x 6186 Vacuum tubes1 x BT Antennae1 x 12v Mains Adapter1 x User Manual1 x AIYIMA Sticker***** Conclusion *****I will start off by saying that this is my first experience of using a tube pre-amp and the AIYIMA brand, so I have nothing to compare it against, but so far I am really impressed.The quality of the T1 Pro seems really good and I love that they have made the product customisable, by allowing the quick replacement of the OP amp chip and tubes.Having Bluetooth connectivity is a nice bonus, as you can quickly pair a smartphone for playback and I like that it supports the more efficient BT5.1 standard, along with support for AptX HD.Connecting the T1 Pro to my existing setup was really straight forward – I just needed to use a 3.5mm to RCA cable between the input ports and my PC and then an RCA to 3.5mm between the outputs and my Nobsound amp. This has given me the ability to adjust the bass and treble and has also given the sound a nicer, warmer tone. I have only used the pre-amp for around 15 hours so far, but I believe the sound will change as the time goes on and usually gets even better.I think the £79.99 asking price is pretty reasonable for what seems to be a good quality product and I shall look into swapping the cheap little Nobsound amp for the AIYIMA A70 to take advantage of the useful 12v trigger function.

A nice addition to my home cinema. Connects really well, with no issues at all. Smooth operation and a wonderful retro design. Amazing.

私が購入した個体には、間違いなく米国ＧＥ JAN-5725W が同梱されていました。使い始めは酷い音に愕然としましたが、20時間以上エージングすると良い方へ激変します。プリ、パワー間は、プロケーブルさんが作った BELDEN 9451（50cm）で繋ぎました。そこそこ良いケーブルを使う価値が有ります。この価格を考えたら、ありえないくらい素晴らしく、しっかりと真空管アンプの音色が楽しめます。Ｄ級アンプのＡ０７ＭＡＸが T1pro を追加する事で、限りなくＡ級アンプの音色に近づきます。中型以上のＳＰなら A-07MAX をモノアンプとして２台使っても T1pro が有れば使い易いので更にお勧めです。メーカーが勧める組み合わせでもあります。確かに A-07MAX 単体でもＤ級アンプらしいシャキッとした音色が楽しめますが T1pro を追異化する事でアンプとしての完成度が向上するのは間違いありません。フルレンジのウッドーコーンＳＰを鳴らしているので、本機のトーンコントロールに期待しての購入でしたが、予想を上回る「大正解」でした。

I bought this preamp for my 55 year old EL34 push pull valve stereo amplifier and it worked fantastic running Bluetooth from my phone. The gain control was a perfect match and the base/treble controls were very effective.I also used it on a more modern solid state amplifier and once again it worked perfectly. I would not hesitate to buy another one in the future.

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.

I have had this compact, well featured, preamp for several months now and have been pleased with the overall performance. Recently I swapped the tubes for a pair of 6J1P-EVs. The sound quality was dramatically improved - the warmth and musicality was just enveloping (I know, subjective). I have this guy paired up to a vintage Bryston 3b amplifier and a pair of ADS L710 speakers from the '70s. I am just loving it for the price paid. In regards to the Bluetooth compatibility, I have streamed from a Samsung Galaxy cellphone and from an Apple iPad without any issues at all.
