Blu2 does the same thing as M-Scaler to DSD source files. However, while it is truly with solo DAVE, playing DSD mode is superior in DSD mode to PCM mode, when you play DSD music through M-Scaler, even though the music is downconverted to 705.4kHz PCM and fed to DAVE, the sound of M-Scaler + DAVE is superior with DSD files is definitely superior to playing the same file in DSD mode straight through the DAVE (without M-Scaler/Blu2). This is because the M-Scaler DSD to PCM conversion is far superior to the DAVE DSD to PCM conversion and to the DAVE DSD mode direct upconversion.The Dave has a setting by which one can select between DSD or PCM in the settings. Some say there is an appreciable difference when selecting the correct one for the format.
"The M Scaler will not upscale DSD sources natively. All DSD data will be converted to PCM before being upscaled. DSD64 will be converted to 192K PCM and then upscaled to the desired amount by using the OP SR button. DSD128 will be converted to 384k PCM and then upscaled to the desired sample rate using the OP SR button. DSD256 will be converted to 768k PCM and will not be upscaled."
Does the Blu do the same thing to DSD? If so, have you listened to DSD on the solo Dave with both (PCM/DSD) settings and what could you hear?
Keep in mind too, this whole concept that some DACs play DSD natively to me is a complete lie. First, since most DSD files are DSD64, most “DSD” DACs at least upsample the DSD64 signal to DSD256 or DSD512. Moreover, they often use a shift register which in itself is a filter of sorts and they use multiple elements so it’s not true that you’re getting a 1-element DSD64 native playback in almost all DACs that are out there. Finally, if a DAC truly plays back DSD64 natively, you’re going to get an analog filter which would affect the sound significantly to filter out the high frequency noise inherent in native DSD64 signal and the analog filter performance is generally quite poor and variable from DAC to DAC. So there is nothing magical or native about DSD playback. Unless you’re going to go back to the old SACD players from decades ago which actually don’t sound that great by modern standards due to more jitter, lack of filtering (shift register/multi-element), etc.
