To solve the Loud sound in the headphones: 1. An amplifier with not too high sensitivity 2. You need to connect a high recognition PC-USB cable Working voltage: DC12V Review: Before going into details below, I will say right away; this is the best price/performance value preamp&DAC I ever used considering the sound quality and so much functionality in a nicely built device. I don't claim to be an audiophile with many many years of experience but I do care about audio quality and I love trying different devices within a reasonable price range. I have tried several budget preamp/DACs/Amp/Integrated Amp combinations to this date and I will write my review based on my personal experience and comparisons. What is included in the box? - USB audio cable - A remote controller with tone controls - Bluetooth antenna to attach at the back - Power adapter (though the cable is not very long, more like a cell phone charger length) - 6N3 Tube for headphone amp (more on this later) - A USB thumb to install drivers and a software for controlling bitrate output though I don't exactly know what it does. - A quick set up guide along with specifications and descriptions of interfaces What is not included? - An RCA cable to connect to an amp if you wanted to use this as a DAC for a hi-fi setup - Optical sound cable - Batteries for the remote (Requires 2xAAA) Build quality - It looks and feels very solid. - I really like the looks of it, it has an industrial look with a bit of a retro feeling especially with the tube and also the wooden pieces on top. - The volume know is the main thing you use and it feels very solid and clicking sound is strong and satisfactory. - Digital display is simple to use and it has useful information with incoming sound bitrate, volume and active input selected. When you change tone controls from the remote you also see those values. - Remote looks cheaper but it does the work and you have to cut costs somewhere. Setting up - It's very straightforward. You plug the power adapter and connect to your PC with the provided USB cable or your own optical cable and that's it. Be very careful when plugging the tube on top, tube pins can be very sensitive and you don't want to bend or break them. This has nothing to do with T8, just be careful in general :) In order to use different inputs, you need to press the volume button to change the input and you can see it on the interface. USB, RCA, BT etc When you switch to BT for bluetooth, it goes into pairing mode and it's immediately discoverable on your mobile device. You pair it right away and it's ready to use. The USB thumb drive includes drivers and a software. I think, you don't need this and manual guide doesn't tell you to install them. It's already plug and play and you can control USB bitrate output from Windows. What is my setup? - Aiyima A07 amp - A pair of Q Acoustics 3020i speakers - Windows 10 PC with USB & Digital out - Mobile phone with bluetooth - Several audio streaming services with ultra quality/MQA output. Sound quality I tried the device 2 different ways: 1- Using with digital inputs (Bluetooth, optical, USB) and connecting it to an amp with RCA cables at the back so it functioned as a DAC 2- Connecting the headphone out headphone out at the front so it functioned as a headphone preamp 1- Using as a DAC With the USB interface it sounds very good. It depends on your personal taste but I thought it felt rich and warm. It sounded very similar to more expensive DAC only devices I used. It supports up to 24bit 192KHz. Make sure to change those settings on Windows for getting the maximum output. It sounded very clear and spacious (though could have been more spacious for my taste) All the instruments and vocals felt very clean and lively to my ears. Optical was similar but somehow I felt USB output produced better sound quality. Which is manageable anyway as you already have a USB cable included and you don't need to shell out extra cash for digital output. It has no benefit over USB anyway. The fact that you have tone controls on the remote control is actually very convenient and adds to the overall value of the device. Changing the settings helps you improve the sound output to match your expectations better. Bluetooth connection gave very clear and lively sound as well but do not expect it to match USB or optical interface. Bluetooth can't match the bandwidth of those inputs. For what you need as setting up a convenient wireless streaming from your phone, laptop etc, this one does the trick and it sounds pretty good for that setup. 2- Using as a headphone preamp Now this is what surprised me. As I said it sounds very nice as a DAC but in fact when you connect a good quality headphone, this thing sounds even better. It provides more clarity and more spaciousness. The reason for that is that when you use headphone out, it actually uses the tube on top. So keep that in mind. People use different types of tubes from different brands. I'm not an expert but I guess it could be effective here as you see the immediate difference of using a tube. So depending on your taste / preference you might actually get a headphone - RCA Y-cable and use headphone out to connect to an amp instead of RCA out at the back. This might change the experience as a DAC too. Conclusion The main point here is the incredible value you get as I said at the very beginning. You can get more expensive DACs or preamps and they could sound better. I'm saying "they could sound better" because it depends on your taste and if you have been investing time and money in training your ears to perceive differences. To me that's not even very noticeable. Those devices would not offer you so much connectivity/functionality. For anything like that with a premium sound you'd normally have to pay A LOT more money. Also don't forget, this thing has a remote controller with tone controls which is very convenient. With this much functionality and such beautiful sound, T8 is easily the best budget headphone preamp & DAC combo I have seen out there. Review: Este preamplificador con amplificador de auriculares lo pude probar de un compañero de trabajo y la verdad que quedé encantado, se escucha genial con auriculares con baja sensibilidad (para los IEMs tiene un problema, puesto que son auriculares con alta sensibilidad y se escucha ruido de fondo, pero es normal teniendo en cuenta de que tiene una válvula). El sonido es muy bueno, las conexiones de bluetooth se hacen con APTX-HD, lo que le da una de las mejores calidades de sonido que ahora mismo existen para BT y el mando a distancia para controlar el preamplificador es genial para colocarlo al lado de la tele junto a un amplificador de altavoces. ## Features - A variety of audio input methods: Support RCA/Bluetooth/PC-USB/Optical/Coaxial input, suitable for iPod, mobile phone, MP3, TV, DVD player, notebook computer, desktop computer and other devices. - QCC3031 Bluetooth 5.0: Supports lossless transmission of APT-X, APT-X LL, faster and more stable signal transmission.

I have put new batteries in twice, but still it will not turn the pre-amp off. Wondering if one can be purchased separately, or maybe a few - just in case this is a case of cheap and not designed to last……. Would like someone from Aiyima or Amazon to respond, because pulling the power cord out of socket is not really what I want to be doing. And the unit has not been used a lot, as is part of a secondary system used with secondary TV.
