“I just love how the Sbooster impacted the sound of my Pro-Ject Stream Box S2 Ultra. It opened up my music tracks considerably and offered more detail vs. the standard switching power supply. I ended up adding a Purple (fuse) to the Sbooster. This too made a huge improvement to the overall sound...even more detailed and even more fun to listen to. Thanks, Guys!”

“Sbooster made a huge difference for my ProjectTube Box DS2 Phono Preamp. Hard to beat a stable power supply!”

“I had been running both my Rega RP10/Alpheta 3 MC and my Pro-Ject Xtension 9/Sumiko Blackbird HO MC through my Rega Aria Phono Pre and wanted more adjustability in order to better match the volume levels. I was able to find a Pro-Ject Tube Box DS2 locally and installed it hoping to resolve my issue. The DS2's adjustability did resolve the volume matching issue but even after extended break in I was not totally pleased with the sound. I remembered the positive effect of power supplies from my Naim Olive days. After viewing Upscale's info on Sbooster I purchased a BOTW P&P MarkII Power Supply and Ultra MarkII Upgrade. Wow what a difference! Hearing is truly believing. What can I say, everything just came into focus. Highly recommended where applicable! The only problem I had is that the Compatibility List / DC Tip Overview is incorrect. Thank you Bill Rudolph for setting it straight! Upscale has a vary satisfied new customer.”

“I bought both 18 v and 24 v supplies for my First Watt B1 pre and miniDSP 4 x 10. I was addressing potential weak links. After about 100 hours of break in, I finally listened. This is subjective but there is a little bit more of everything - dynamics, detai and musicality. It is not sterile but instead well balanced and full of life.”
