Transporter i9 and multichannel DSD

I don’t know.  If your ears can tell a difference between DSD 64 and higher than I salute you.  Kalman Rubinson has written about these products, I think, when he had a regular multichannel column in Stereophile.  You may want to check their index

Hi Mahler,
thanks for your answer re multichannel management in the SGC Transporter i9. I try to find K. Rubinson's column. The quality improvement with higher than DSD64 is a clearly heard lower S/N.//Jan
