I've been listening and collecting SACDs for almost a decade, my impression of SACD and now DSD downloads are always sound more 'analog' than PCM. Noise gradually rise up at 22kHz and above for DSD64, while DSD128 will start to rise above 44kHz and so on for higher sampling rates. Also note, noise of DSD gradually rises up instead get chopped off abruptly like in PCM. The response impulse is almost analog in nature and have much lower noise floor up to 15kHz than conventional 24bit PCM. The whole idea behind DSD superiority is the avoidance of decimation in the front end (ADC) and harsh digital filtering end point of DAC. And we can either calling it Multi-bit DSD or Hi-res PCM. Something like 3072KHz 32bit float/24bit int. I think in future, we are going to have hybrid format between DSD and PCM. Some of my friends found this preferable. And yes without proper LPF, ton of high frequency background noise. More dB on low and mid frequency while less on high frequency.

If you converting PCM to DSD (I test it with foobar in PC/Audirvana in MAC with ES9018), it sound like you EQ the song. Well some people are prefer DSD because of their downside So why bother with DSD when 384KHz and 768KHz DAC existed? If studio recording or editing in DXD? Yep, very few doing good job while most of them doing poor job in recording and editing. Though, very few studio recording/editing in multibit-DSD and no conversion between DSD and PCM. Therefore, in editing process, either it was converted to multibit-DSD (DSD 8bit) or DXD (PCM 384kHz 24 bit int or 32bit float).Īnd conversion between DSDPCM is not lossless. Volume control with 0.5 dB step size and soft ramp.I²S, right-justified, left-justified, DoP, DSD and TDM interface.Supports up to 384 kHz sampling frequency.Eliminates distortion due to on-chip component mismatch.Advanced 32-bit oversampled multi-bit modulator with mismatch shaping technology.Increased hi-fi DSD playback rate from DSD128 to DSD256.Evolved performance: THD+N increased from -108 dB to -115 dB.CS43198 is the evolution of the CS4399.The CS43198 is available in a 40-pin QFN or a 42-ball WLCSP packages.ĬIRRUS ROCKS ® CIRRUS ® ENGINEERED TO ROCK ® INNOVATION THAT ROCKS ® Volume matching of the analog output levels and channel mixing enable a seamless transition between the DSD and PCM playback paths. A patented on-chip DSD processor supports up to DSD256 in direct mode to preserve audio integrity by providing non-decimating volume control with soft ramp, and 50 kHz filtering as recommended by Scarlet Book. Filtering options include low group delay with pseudo-linear phase and a fast or slow roll-off. To minimize pre-echos and ringing artifacts, the CS43198 is designed with proprietary digital-interpolation filters that support five selectable digital filter responses. The CS43198 features a high impedance of 600 Ω, a 130 dBA dynamic range, a THD+N rating of -115 dB, and inter channel isolation of >110 dB. This IC minimizes board space requirements while enabling performance and features to drive design differentiation. The CS43198 is a next generation, low power audio DAC that provides a superior system-level audio performance without draining battery life.
