Oh no...Here we go
Danny: What are you thoughts on DSD? I could buy a Schiit Loki for $149. But DSD source material is limited/expensive. Is it worth it?
DSD is great, as long as you've got the speakers to exploit it (the assumption is the 901 is also very capable). The SMSL is peanuts in the scheme of most systems, a real bargain for the ES9018 if you know what your goal is. I demo our speakers a lot and the Mac Mini with SSD to the DAC (which JRiver has a plugin for) is a very good way to show not only the difference in musical pieces but their path (DSD either streaming online or stored) and their sample rate (the SMSL switches automatically).
Today at a show in Melton Mowbray, UK, a room had an A,B,C demo of DSD, PCM and CD (AIFF), it was fascinating and people could mostly hear an audible difference, if only the system was more capable the upper reaches of the DSD files would've made the experience less 'hearing test' and more 'obvious enlightenment'.
If I could mention the vol pot. As I say I do many demos, I have no issues, I got into the habit of going thru the switch on routine and before tapping the face switch I twiddle that lovely billet volume knob - it's like petting a faithful friend, no autum leaf rustle for me
