Finally, about a month after receiving my JS-2 and MMK from Alex, I was able to be home, have the tools, and the time to do the installation. Here are some of my thoughts... THE GOOD 1. I've just turned on the Mac Mini (late 2014 PCIe Flash) plugged into the JS-2 and it does sound really good (I can't quantify the improvement, but it's definitely there)! 2. Fantastic service and support from Alex (Superdad). I had a few questions over the past few weeks, initially with the order, and then some clarification questions, all of which Alex responded very quickly to! 3. Really nice build quality on the JS-2 (see picture below). I personally would have preferred not to have any text on the front fascia, but no biggie. COULD BE IMPROVED 1. I consider myself reasonably "tech comfortable", but even so I have to admit that I put off the installation project more than a couple of times because of the rather scary-looking documentation - granted, probably every step needed is described nicely by Alex in the little booklet, but it's in very fine print (a tad challenging for my nascent presbyopia), and there are no pictures! Not one (well, except for the cover photo)! 2. Having said the above, Alex did very kindly send me emails with iFixit links, for the tear-down (first part) of the installation. However, one will still have to read the documentation very carefully to figure out the second part, as it (of course) isn't on iFixit... 3. What made it a tad more worrying was that the documentation was obviously prepared some years ago - the very first line says "Install this product only in a 2010, 2011, or 2012 Mac mini". Alex did clarify in an email that it would work fine on my 2014 Mac mini, and did also describe some of the differences between the documentation and what I would have to do for my newer unit, but it did add to my fears (and the complexity)! 4. Another problem was that the Torx 6 Security bit, which is required to open the late-2014 Mac mini, is not included in the toolkit that Alex sends out, so I had to purchase it from iFixit separately. 5. There is no documentation at all as to how to use the JS-2. At first I didn't worry because, after all, there aren't that many connections! However, for the first few minutes after turning it on my Mac Mini refused to start up, until I figured out that the "sense" cable was loose, and also that I had to have the little switch at the back set to "sense", and that the DC cable had to be connected to the DC-2 output (in hindsight it is obvious, since it is the output closest to the "sense" input)... SUMMARY In summary though, I have to say that the actual installation process is very, very easy to do - it just looks difficult to those of us accustomed to having pictures to follow-along to! The resulting sound quality improvement (at least to my "freshman" ears) also sounds pretty good! And again, Alex was fantastic in being very prompt and helpful with his email replies! I've provided some photographs of my installation below, as it may be helpful for others in the future (do note that in the second-last picture the switch/sense is set wrongly - I took that photo while trying to figure out what was wrong). Art p.s. As mentioned, for the first (teardown) phase, I used this guide from iFixit:
Ciamarasound posted a topic in Ciamara (Sponsored)The SBooster Ultra for the UpTone Audio Regen USB Hub is their first switch-mode power supply add on based on active filter technology. Compared to the passive SBooster Single Unit you will get with the Ultra an even greater crispness, tightness, distinctness and focus. Last but not least your Regen will run a lot cooler which has a positive influence on the overall sound quality. The SBooster Ultra upgrade for the Regen is a plug & play addition to your stock supplied Mean Well switch-mode power supply (MW SMPS). The SBooster Ultra uses active filter technology to purify the high frequent ripple and noise of the MW SMPS. Furthermore the Ultra also enhances the poor power characteristics of the MW SMPS completely in order to get the maximum sound quality out of your Regen system powered by a switch-mode concept. With the SBooster Ultra you get high performance, but still economic upgrade option for your Regen. The SBooster Ultra upgrade improves following aspects of the SMPS and Regen: Reduces ripple and noise of the MW SMPS; Improves the stability of the MW SMPS; Lowers the internal power dissipation of the Regen. The SBooster Ultra for the Regen will be delivered as a plug & play device and requires no technical knowledge. The Sbooster Ultra has to be used in combination with your stock supplied 7.5V Mean Well (switch-mode) adapter.

SBOOSTER "BEST OF TWO WORLDS" AUDIOPHILE POWER SUPPLY (BOTW P&P ECO) The Sbooster “Best of Two Worlds Power & Precision ECO” audio upgrade (BOTW P&P ECO) is the successor of SBooster's “Best of Two Worlds Solutions” audio upgrade (BOTWS). This new upgrade product combines power, precision and efficiency in an unique innovative manner that purifies the incoming current immediately upon entering the device. A dual stage mains filter and an earth line choke clean the current from high frequency pollution before the current reaches the transformer. The transformer is a custom-made audio grade transformer with electrostatic shielding. The electronic design allows for up to 50% more output out of the used electronics and consumes even up to 35% less energy than a conventional design. Even though it provides a significant boost in available power, the BOTW P&P ECO audiophile power supply is so efficient that it consumers only a fraction more of electricity than what a standard power does. ULTRA ACCESSORY The Sbooster Ultra Filter Accessory can be used as an addition to the many filtering and optimization techniques of the BOTW P&P ECO audiophile PSU and can only be used with the SBooster split-current module of the BOTW P&P ECO. The Ultra is based on active filter technique, which reduces the ripple & noise of the BOTW P&P ECO even further: to a negligible low level. The Ultra is designed for audio equipment that is highly sensitive to residual noise, such as digital to analog converters, music streamers, USB to SPDIF converters, headphone-, pre- and phono amplifiers. In addition to the active filter function, the Sbooster Ultra also re-stabilizes the output voltage to the correct voltage and because of the short cable length of the Sbooster Ultra, the highly purified powered is passed to your audio device with no performance loss . Main benefits of BOTW and Ultra Filter Accessory: Up to 50% more power to your amplification components Lower noise floor and blacker backgrounds to your digital components Improved musical rhythm and timing These products qualify for Free Shipping and 5% back in points when you register for Club Ciamara Membership Rewards Program 1.844.CIAMARA (1.844.242.6272) High End Audio Store NYC - Experience Ciamara
