The C521i is a simple and effective player. It is prcis transcribed in the sound and allows it to enjoy a music ncessitant raction fast prcise and nuance (jazz, rock, electro, pop and soul records are his pr dilection). In terms of keys and functions, nothing spectacular. Note, however, output numrique in connectors and gold plated terminals, which is to Chf 560 CHARACTERISTICS commendable.
Trs reliable. The flip side is that you must rely on Sampling levs when insrez him a burned CD is more your Sampling lev over the quality will be better. You can even prod diffrencier good on a bad cd professionals. He does not accept mp3 unconverted.
The quality of sound is Drout in this price range. I can only recommend it.
A wise guy slipped a turtoriel insrer speaking of cleaning the cd's and some lments disassemble for cleaning the lens. DO NOT PLAY WITH THIS UNIT CA. DEATH IS ASSURED FOR MATOS!
