Vinyl lovers like to have everything analogue. But what if you want to transfer music wirelessly from your turntable?
There are already some record spiners with the possibility to transfer the music via Bluetooth, like for example the models from Teac that have a BT in their name . The transmission is done according to the aptX standard.
Cambridge Audios turntable plays in a different league with around 1,700 dollars and features a better codec: aptX-HD. This increases the data rate from 352 kpbs to 576 kbps. In addition, the HD variant allows high-resolution signals to be transmitted, i.e. up to 48 kHz sampling rate at 24 bit. The codec that competes with Sony’s LDAC thus offers better quality, but is still not completely lossless.
However, the question arises as to whether this is of importance when playing a record: aptX-HD can handle frequencies of up to 20,000 kHz and a dynamic range of 120 dB. In practice, the signals of a vinyl record are usually significantly lower – you probably won’t hear any difference even with good equipment. However, the signal chain is no longer pure and analog. The ALVA TT is a combination of classic pressed vinyl and the latest algorithms that might appeal to everybody who loves classic technology but lives today.
