Hello together, I’m just facing a little problem because I don’t know which radio to buy. On the point: Actually, the Alpine CDA-9853R was my favourite. Among other things, because I already have an Alpine Ai bus changer. But my CarHifi dealer advised me from this device and recommended me the Sony CDX-F7750, because this radio apparently – unlike the Alpine – has integrated some processor functions already. So far, so good, but what me It is surprising that the Alpine is several hundred euros more expensive than the Sony. Here is the statement of my CarHifi-man:… but I would never recommend an Alpine radio under about 500 euros on radios up to 300 euros there is only one with top sound of the Sony CDX F 7750 with 4 volts and 3 outputs (front / rear) & subwoofer with built-in active softness and pre-all MP BBE which greatly improves the sound and the Dymamic, which sounds with its 24 bit Burr Brown D/A-Wa I’m looking forward to your opinions!
