“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.”

“Easy to attach and worked flawlessly from the beginning. I have it connected to my Roon Nucleus. I have not tried the Roon with and without this power supply, so I cannot specifically describe any improvement it might have made.”

“Right out of the box I noticed no noise except the recording. As I continue to use it I am seeing more individual instruments with space around them. This is a good investment.”

“Significant upgrade for the Roon Nucleus; if you’re on the fence and have gotten this far, pull the trigger. Much more there, there…”

“Purchased an Sbooster BOTW P&P ECO MKII Power Supply 18-19V for use with my Pro-ject DS-2 tube box as the pre-amp comes with a wall adapter. wanted to improve the power to the unit. As suggested by Upscale audio, the Sbooster provided all the improvement I hoped for. Ordering from Upscale was a pleasure and they provided fast shipping and great advise. Thanks and appreciate the great experience.”
