Audioengr - is the SM5847AF chip in the North Star used in the AES/EBU output that allows for 24/96 upsampling, or the I2S output that allows for 24/192 upsampling, or both? I have been using the AES/EBU output and letting the North Star upsample to 24/96, which can be read by my Monarchy DAC and it sounded suprisingly better versus Redbook. I'd like to try the I2S, but the Monarchy doesn't have an input for this. Would this be a mod you could take on? I believe the Monarchy uses the CS8414. Feel free to respond here or email me offline.
