It is a tube buffer for those digital signal like as CD, MP3 player, and your smart phone, that adopt 2 pcs Beijing thumb tube 6J1 which is used on more famous tube preamplifier, and designed as HIFI cathode output circuit. And those component also adopt HIFI grade one.
If you are tired the Bluetooth speaker by mass production and want to find a unique Bluetooth speaker manual with good sound quality, you can come here to check it out.
The greatest feature of Bluetooth audio decoder or Bluetooth audio amplifier is that give up traditional wired connection, use Bluetooth technology to connect mobile phones, tablet and other electronic terminals with them.
This speaker completely overthrew the concept of speaker-making, speaker adopted Labyrinth cabinet structure that will get well effect but the structure is more complex, limiting its development. Through we continuous the efforts, we make a revolutionary new speaker for 2 inch full range speaker.

These "better DIY RCA interconnects" are unbalanced and made using shielded instrument cable and high quality RCA plugs. This is a fairly easy DIY cable and one stereo pair of DIY interconnects can be put together in about one hour. You will not need any fancy materials or special tools to build this cable. Just some meters of good shielded instrument cable and high quality RCA connectors, a soldering iron and some good solder with flux, a handy knife and a good side-cutter to prepare the wires for the soldering process. The photos only is as an example to demo how to DIY shielded RCA Interconnect Cables.
