Singapore Hardware zone heeft een review van Diamond's Rio MP3 walkman gepost. Een leuk apparaatje, dat ook z'n slechte kanten heeft:
ne main complain of this Rio player is the insufficient amount of base memory. With 32MB built-in ROM on board, the Rio can only contains up to 8 to 9 songs ripped off a CD. If Diamond could increase the base memory to 64MB, a complete albulm of CD songs will be able to reside comfortably in the Rio's memory for portable listening.
The earphone that comes packaged with the Rio is definitely not suitable for serious listeners. It is not able to reproduce any bass signal at all. In addition, I find that the built-in graphic equaliser on the Rio could have been preset better so as to bring out a greater difference between each settings.
One last point is that somehow or rather, I feel that the black plastic casing that houses the Rio player does not give it a sophisticated or sleek design. Comparing it with most of the walkmans manufactured by Japanese companies, these portable players usually endorse a metallic casing so as to give them a really sleek design.
