Advance Paris X-FTB01
The X-FTB01 is a Bluetooth aptX+AAC (Apple) receiver that can be connected via the Bluetooth digital input on the back of certain Advance equipment.
The X-FTB01 does not send the received digital signal from, for example, a smartphone, tablet or computer via its own built-in simple DAC to an analog input (see WTX 500), but sends the digital signal via a direct connection to the internal DAC of an Advance amplifier. This way you use a high-quality DAC, resulting in a perfect transmission with exceptionally good specifications, such as a distortion rate of 0.008%!
The X-FTB01 is very compact and does not protrude further than, for example, a connected cable.
