C1是1704无误。
“The digital to analog conversion stage of each channel is handled by four Burr-Brown PCM 1704 R2R chips.
While total harmonic distortion (THD) figure of top R2R conversion chips (such as PCM 1704 used in C1) is slightly less impressive
than those of Delta-Sigma technology based converters, their temporal behavior (on transient events which music is filled with) is
inherently better. The high frequency behavior (above 20 kHz) is also much more accurate and free from modulation noise that
often disrupts treble speakers (tweeters), as high energy content into the 20 kHz -100 kHz band can not be handled properly by
most tweeters.” |
