To calculate the overall star rating and percentage breakdown by star, we don’t use a simple average. Instead, our system considers things like how recent a review is and if the reviewer bought the item on Amazon. It also analyses reviews to verify trustworthiness.
Work for everything but my turntable (stereo), the phones has no pre amp - previous pioneer amp did (home theatre). No SPDIF port ?!?!?!. 2 set of speaker outs, Bluetooth works great - Overall sound great!
