I first considered the Onkyo 530 based on brand reputation, specs. and the music file feature. When I auditioned the unit I compared it with Sony, Harman Kardon, Technics and Kenwood. I didn't expect to hear a discernable difference between the units. However I consistently picked out the Onkyo and the HK without knowing which unit was playing. I was informed by the salesperson that both the Onkyo and the HK used the same quartz-pulse technology (whatever that is). They were both clearly superior to the others (especially the Kenwood). I went with the Onkyo because of the disk memory system even though I paired it with a Harman Kardon AVR25 receiver. I've had it 18 months and have nothing but praise for it. I've read several complaints about the HK units and feel I made the right choice. I highly recommend the unit and give it top rating.

A wonderful unit. Quality, ergonomics, and sound are all top-notch.
