It looks the same specs and is less than half the cost of the JS-2. I have ordered the MMK kit from Uptone Audio, but was thinking of getting the cheaper HDPlex PS. No regrets whatsoever from any of the UpTone products. This was on my system, with both speakers and headphones. The actual improvement from the JS-2s and the conversion kit was a noticeably lower noise floor with the associated improvements you would expect from that. In my system, the Mac mini conversion with the JS-2 provided a greater benefit than the Regens, which surprised me.Īll in all, I have become a believer in the importance of quality power. I expected a subtle change, and was quite surprised at the magnitude of the improvement. I am using the JS-2 to power both the mini and my external Firewire storage. I installed the DC-Conversion/Linear Fan Control when I received the second JS-2. The JS-2 was a noticeable step up over the stock SMPSs, so it stayed. Initially ordered one JS-2 with the mini conversion kit and made the mistake of experimenting with the JS-2 powering my twin Regens and Icron Ranger 2201 (Rex).

I have two JS-2s and a 2010 Mac mini with the DC-Conversion/Linear Fan Control. The company also market the Regenerator USB box, though I don't require that in my system. This unit has 4 years warranty and is made in NY. It retails at $925 so not so cheap, but Linear Power Supplies are not cheap anyway, unless from China with suspect build / life. The Power Supply unit has 2 variable outputs, so for example you could power your DAC with 9V DC and your Mac Mini with the required 12V DC supply from the second output. So I shelved it, but recently am coming back to the subject.Īnyway, I have found many very positive responses about this Power supply: I had read various posts in the past on other sites about the Mojo mods to the Mac Mini itself and the PS, but soon after that company popped up, the negative experiences started coming up. I run Audirvana+ and get asyncronius direct mode on it, and after trying other software, am sticking with that. This leaves me staring at my little Mac Mini 2013 model. I have already got the available tweaks / upgrades done or lined up in my Audio Note DAC. Is there any more (hopefully) affordable gems hidden in the rest of my source gear. Plinius SA-103 power amplifier last month, and hearing how it cleaned up the sound in my gear even more, it got me thinking. After I bought the PS Audio P10 to power my DAC, KGSShv.
