Hello! I read a lot on your forum and thought about buying topping d50s! I'm asking for your help! I want to buy d50s to upgrade my hi-fi system! I have a Denon DCD 800ne player and a Cambridge audio azur 640A v2.0 amplifier, ELAC fs 58 speakers! the first question is should I buy d50s for cd playback (will I improve the sound quality?) And the second question! am I thinking correctly about connecting! initially denon player from him through optcheskiy cable on d50s, and from him through rca on amplifier on input cd or aux! I will be grateful for the answer! I can't find the answer anywhere! thanks in advance!
