After a night of listening, I have to say, that the DPS does offer a noticeable improvement. I was skeptical before purchasing, but now I'm glad I did. The best way to describe the improvement, is if any of you ever had a Rega turntable and if you replaced the stock subplatter with a Groovetracer reference subplatter (or some other machined subplatter). Every thing became more focused and crisp. Vocals are spot on and imaging seems more accurate. I did have to adjust the speed after adding the DPS, but everything is on point.
I definitely recommend the DPS.
