The best sound is still provided by traditional analog media: tape and vinyl. However, they have four disadvantages: a limited repertoire, impermanence, high price and inconvenience of use. It is therefore a digital source necessary in the system, and the best is a dedicated computer – audio streamer.
We now offer three models of audio streamer under the brand LiveBit: Number Four, Number Three and Number Two. The top model, Number One, does not yet exist – we are waiting for the development of data transmission I2S technology (better than the currently widespread USB). The three available models differ in power supply. Number Four has an internal, typical PC ATX power supply. Number Three has a a simple external power supply 12V and a separate linear power supply 5V for USB card. Number Two has an additional external audiophile linear power supply 12V.
LiveBit is a computer running free software Daphile, which is both Linux operating system and a music application handling all digital audio formats (Linux is the most audiophile system, incomparably better than iOS and Windows due to its simplicity).
Daphile accepts files from three sources:
1. CD (LiveBit has a conventional optical drive)
2. hard drives and pendrives
3. web radio
Daphile may be operated in three ways:
1. through a web browser installed on a second computer (laptop) connected to the server LiveBit via Wi-Fi (internet access is not necessary, Daphile creates its own hotspot that works even offline) or via an Ethernet cable (this method provides the full functionality of the operating system)
2. through an application such as Logitech Squeezebox on your Android smartphone or tablet (only music playback control)
3. via a connected monitor and keyboard (the simplest control of music playback).
Those mentioned control devices are not included in the kit LiveBit.
The components used in LiveBit are carefully selected according to audiophile criteria and complemented with hardware noise filters. BIOS settings are sonically optimized as well, e.g. we use CPU downclocking. LiveBit Number Three and Number Four have passive CPU cooling, that is noiseless, and that used in Number Four is very quiet, almost inaudible.The output signal is held via the USB port in a special audiophile USB card.
It is therefore necessary to connect to LiveBit an external sound card, it means USB DAC (digital to analog converter with USB). If you want to play DSD files without conversion to PCM (and this is by far the best sonically digital format), your DAC has to support DSD files, at least in the DoP protocol and preferably NativeDSD.
Since the copying files to the disk in Daphile is slow, LiveBit servers have installed only one small capacity SSD (80, 120 or 240 GB). The larger music library you need to prepare on another computer on an external HDD (than connect it to LiveBit via USB) or internal drive (than mount it in LiveBit housing).
