Many thanks for the quick responses folks! Always amazes me how responsive this community is!
Special thanks to Ted - I hadn’t realized about the sample rate limitations for the non-USB connections. This is a bummer as I have an increasing collection of DSFs I rip from SACDs.
One of the reasons I was thinking of making this change is as I’m trying to track down/reduce the source of some noise in my system. It used to be perfectly black before my recent equipment changes (macbook —> mac mini (but with linear power supply), Chord Hugo —> Directstream, Woo Audio WA5 —> WA234 monoblock amps), but now I get a distinct (though admittedly faint) crackling and squealing every so often (noticeable especially when using headphones).
The crackling disappears when I disconnect the source cables leading into my amps, so it looks like the problem is upstream from them…
There was quite a bit of improvement when changed my Directstream->WA234 from Chord RCAs to Nordost Valhalla2 XLRs last week, which is why I started thinking about trying a different connection between the Mac Mini and DS.
A friend suggested I try removing the ground pin on my main power cord, but I haven’t dared do that yet, and not sure if it will make a difference (I’m using a P10Power Plant and Valhalla 2 power cables). Do any of you think this will make a difference? Or could it be the Mac Mini, even though I’ve replaced the power supply with a linear one (Uptone Audio JS-2 and MMK kit)?
