I recently upgraded my CD player from an NAD 513 carousel to a Rega Planet 2000. The NAD had a warm sound, and I liked it OK, but I have noticed a significant improvement in the low level detail, more extended bass, instruments and voices sound more real, it is just an overall improvement. It also has good build quality and operation is simple. My CD's are all "redbook", and I have no intention of going to SACD or DVD audio at this time, and I unfortunately had to make price a consideration, so the decision was based strictly on the best quality I could get for under $1K.
