I received my DSD Sr and hooked it up today and all I can say is WOW! I am running B&W 800D3 powered by Sim Audio 1kW Moon Rock Monoblocks and previously was using the Benchmark DAC3 HGC as my DAC/pre-amp.
Installing the DSD Sr. has been the most significant improvement to my system since I bought my B&W 800D3. The sound stage has widened by a factor of two and the bass, oh that bass- it is so much more articulate and ever so present. I expected to hear an improvement coming from the Benchmark DAC3 (considering its excellent measured performance) but the night and day difference between the two is incredible. The Benchmark almost sounds like I have earplugs in when listening compared to the DSD Sr. Coming from an Engineering background this is tough for me to say, however, it goes to show you that measurements aren’t absolute and there is much more to the story when it comes to audio equipment. I have only been listening for about 2 hours now and can’t wait to hear how the DSD Sr. evolves as it is broken in.
The only down side to me for the DSD Sr. is that without the 20dB attenuation enabled I get very loud hissing from my 800D3. Enabling the attenuation eliminates the hiss but now max volume on the DAC is loud but not as loud as I would like to be for when I really want to crank up the system. I guess this means I need to start saving up my pennies for a BHK pre-amp?
Well done PS Audio, what an amazing product! Also thank you to Walter from Underwood HiFi for giving me an excellent deal!
