Hello, your old RX-470 already seems to have an integrated amplifier, and you also have another amplifier that is certainly also good and powerful. This means that you "only" need modern DAB+ reception. A pure DAB tuner without an integrated amplifier is sufficient for this. The R-S202DAB is o.k. for this, but somewhat modest in terms of DAB functions (limited ability to store stations etc. see the other reviews). My suggestion: Buy a well-equipped tuner with additional functions, e.g. the: Renkforce RF-DAB-IR 1700 HiFi tuner DAB+, FM, Internet radio, Bluetooth, WLAN DLNA-capable.
