Thanks @jussi_laako, I have some other questions for you if you don’t mind?
I find that I am experiencing some crackling or pops while using the SMS 200 network player that I do not experience when just using my MacBook Air as Core Audio, and as such I have had to alter the bit rate value to prevent the crackles and pops on the SMS 200. So with the MBA I can achieve DSD256, but only DSD128 with the SMS 200. This is maybe not a massive loss, but is there anything I can do to achieve DSD256 with the SMS 200? Perhaps you might even suggest I make other alterations to the settings to achieve maximum performance from the SMS 200?
I don’t know if it helps or not, but the DAC that I am using is a Topping D90.
These are the settings that I am using with the MBA as core audio.
These are the settings that I am using with the SMS 200 as NAA
Thanks
Edit. After playing songs for an hour or so this morning using the SMS 200 at 48 x128 bit rate I have just noticed some pops happening. Prior to this I am fairly certain there were no pops.
