Happynick, I bought the upsampling kit for the MSB III. I find no difference whatsoever. The kit comes with switch that allows you to switch between the two MHZ settings. I noticed no difference. It could be just me though. Also, perhaps the upsampled setting is less fatguing over longer listening periods. Personally, I'd spend my money elsewhere on your system. Good luck.
MSB link III upsample upgrade worth it?
What can I expect from the upsample , I have a pair of Martin Logan Aierus speakers will it help get rid of some of the harshness? Any comments welcome thanks, Nick
