An UPSAMPLER that takes the standard 16 bit 44.1 CD digital output and upsamples to 24 bit 96khz which has interpolative algorithms and is then D to A decoded by a 24bit 96 khz can make almost astonishing improvements on standard CDs. Until recently the best known units were from dCS and were five figure investment. Just recently MSB and Perpetual technologies have released much more reasonable products. I'll have them to compare in about two weeks and will report back.
