I did notice in the Sterephile review of the MSB link dac III with upsampling that you have to flip a toggle on the back of the unit to engage either HDCD or the upsampling mode but not both. I have many HDCD discs but not a HDCD player. I have been looking at maybe upgrading by way of the MSB unit mentioned above. I will have to find a dealer who has a unit with both options installed so that I can compare the difference. The upsampling in the MSB is 133khz. Can anyone comment on 133khz vs HDCD? If the upsampling option is better then the engineers must have wasted their time with the time and expense of mastering those discs with HDCD. Seems odd to me.
