I have recently been working on my audio system to improve sound quality and to reduce the physical size needs of the system. I also wanted to have a Mac as the control computer. To that end I have an UpTone Audio JS-2 powering my Mytek DAC+ and a new 2014 Mac mini. I thought I would post a few pictures and some notes about my install. Thanks to @Superdad for the great products and support! The Mac mini is a 2014 model with 16GB of RAM and a Core I7 processor and 512GB of PCieSSD from Apple. If you have taken an older mini apart there are some subtle differences that are covered in the help from UpTone Audio. I took a bunch of pictures that should help others along with my own visual memory! To start with the 2104 model has a different base that you have to "pop" off instead of twist off: After you remove the bottom and take off the internal cover with the WiFi antenna the fragile antenna cable has to come off : Next you have to remove the fan. The little connector pops up from the board and there are three screws holding the fan down: Next you have to remove the IR and the PCIE connectors: (That PCIE thing looks scary so be careful): Now you have to remove the one screw holding the mother board and tray into the computer. You also need to disconnect the power supply connector from the motherboard. I forgot to get a picture of that but you can see it next to the PCIE connector above. Note that the first time you try to slide the mother board out it is HARD to move. You cannot take it off until the mother board is partly out of the Mac: Now it is time to get the power supply out. There is a single screw holding the power supply to the case. You can see it in the picture below. I did not get a picture of the little catch holding the connector to the case!! Follow the notes and the fixit docs. Also do not lose the rubber boot for the power supply AC connector you will need it if you ever reverse this process: NOTE: I forgot to put the washer and the screw back into the case to hold the frame down so maybe do that NOW!: Now it is time to get the new power supply interface board into the system. You need to hook up the power supply connector and the interface cable to the new fan controller: Check the tape on the bottom of the PS board and slip it carefully into the motherboard mounting frame: Following the interactions put the washer and the nut on the DC jack. I did not put the optional nut on the coax jack: WHEW we are getting close. Plug the power supply cable into the mother board and we are ready to CAREFULLY slide things back together: Since the Website will not let me upload any more files I will continue this with a second post...... -RJF

View Classified Uptone Audio ISO Regen + 2 x USPCB's For sale is my ISO Regen. Includes: - original box, - two (2) USPCB USB A > B adapters (one "standard" version, and one 90-degree angle USB B plug version for vertical placement of the ISO Regen/other USB devices) - upgraded power supply to the Uptone Audio-branded SMPS instead of the original, older Meanwell SMPS that came with the unit. The Uptone Audio-branded SMPS is one I have left over from a now dead Ultracap LPS-1, and should be at least a nominal improvement over the Meanwell stock supply. Still, I used the ISO Regen with multiple LPS's, including a LPS-1, a Teradak 30W, a Linear Solution LPS-912, and a Paul Hynes SR4 Turbo, which the ISO Regen scaled to very well and improved which each higher quality LPS it was tried with. I am only selling because I upgraded to a far, far more expensive SOtM tx-USBUltra Special Edition, and the ISO Regen is just sitting around. Given that the SOtM is literally over five times as expensive, the delta between the two of them is definitely not as big as you would expect, especially when you power the ISO Regen with a very good LPS. Priced low for a quick sale, but will entertain all offers. Price includes shipping in CONUS. I am the third owner. Seller internethandle Date 01/14/21 Price 160.00 USD Category Accessories

Just a cautionary note for anyone wishing to purchase anything from Uptone Audio. Over the past 3 or so years I have owned an ISO Regen, two LPS 1's and two LPS 1.2's. When they work they are OK. However, when they do not, you cannot really count on any meaningful support from Uptone Audio - under warranty or not - and even more so if you are not in the US. One of my LPS 1's failed during the warranty period after less than a year of use. It would not output anything. I contacted Alex Crespi of Uptone who arranged for a replacement. I shipped the faulty LPS 1 back (costly). I received a replacement in about a month. The replacement I received had dings on the case that were not there in the first place. I just chalked it up to shipping issues. Two months later, the replaced unit failed again. It would not light up. It had more than a year left under warranty. I contacted Uptone again who requested I ship it back again for replacement. However, they discouraged it and proposed a credit of US$185 towards the purchase of a new LPS 1.2 in lieu of the warranty on the unit which faltered so quickly after it was replaced. Upon further questioning and correspondence with Uptone, it came to light that they had not repaired the unit I had sent in for warranty replacement with new parts. Instead they had replaced the board with parts culled from used and returned units previously sent in for trade in or repair purposes. In short, the warranty is tantamount to having your unit replaced with a used one which may or may not have been faulty in the first place, which they claim to have "tested". It is no surprise that the unit faltered so quickly after their supposed warranty replacement then. As such, their so-called warranty replacement is pretty much flawed. Alex got defensive and quoted some self-derived metric about the failure rates of their products being extremely low and put the cause of successive failure in my units down to my bad luck. He also said that I had electrically damaged the unit which is baffling since I had used it only with their supplied OEM Meanwell switching power supply which still works fine up till today. To date, in the last 20 or so years of being in the hi fi hobby, these Uptone products are the only ones to have malfunctioned so badly. Wishing to cut my losses and to avoid having to ship the faulty unit back to the US at costly charges when the "warranty" replacement would most likely fail again shortly, I paid the remainder towards a brand new LPS 1.2. Alex made it clear that he would not assist with repair of the faulty LPS 1 and I disposed of it. I received a shipment of the LPS 1.2. However, when I unpacked it, the unit had a clear rattling noise when removed from the box. Upon closer inspection, there was a slight scratch on the front chassis plate and the screws were badly stripped. It was pretty clear that Alex had shipped me a used unit or one that had escaped their seemingly lax quality control. I contacted Uptone immediately and requested that they make arrangements for their carrier to collect the unit from me for return to them and replacement of a brand new unit to me. Alex admitted to their negligence citing size slippages and disparities in their OEM case specifications which caused the misfit and rattling noise and worn out Torx screwdrivers stripping the screws. He was certainly aware of the issues affecting the unit I was shipped. However, he refused to do anything about it. He suggested that he would send me some screws and that I open up the unit myself and mount some electrical tape inside the case to stop the rattling noise. Again, he seemed to be fully aware of the issue and how to fix it. Unfortunately, I am not technically inclined nor do I own a Torx screwdriver. To render those fixes I would have to pay a technician to do so. This is rich considering that I had paid for a new and finished product and was shipped a used and/or damaged one. I wrote back to insist on a replacement unit being sent to me and that Uptone arrange to cover the return shipping costs to themselves. Again, Alex refused steadfastly and got hostile, saying that I was taking advantage of them. How exactly am I taking advantage? I paid full price for a new and finished product - that is all I expect, no more and no less. Alex also stated that he did not wish to lose any money on this sale even though Uptone offers the best customer service possible. His final offer was that I return the LPS 1.2 to them at my own cost and that he would refund me the US$250 I had paid meaning I would have to write off the US$185 credit value on the disposed LPS 1 which he is contractually obliged to repair but had refused to assist me with. In this whole experience with Uptone, Alex strikes me as someone who is simply full of excuses. He pays lip service to providing good customer service but it is really just marketing talk. When it comes to the crunch, he fails to deliver but instead makes excuses and puts the blame on anyone but Uptone and himself. Outrageously, he even believes in his own self manufactured press. I recall earlier correspondence with him on why the Uptone ISO Regen would disconnect from my DAC for no reason, requiring that I unplug and replug the DC cable from the Uptone LPS 1.2 for it to work again. Not knowing that I was powering it with a LPS 1.2, he began by questioning the power supply I used. When told it was a LPS 1.2, he blamed the issue on the Silanna chip Uptone used in the ISO Regen - after all, it was an Uptone supply and he could not blame that anymore. I mean you manufactured this product, sourced and supposedly tested the parts and then sold it to the customer as a finished product for good money. The sheer lack of responsibility, ethics and professionalism! As an example of Alex being purely a marketing act, you can see on the Computer Audiophile forum how he derides Sonore's optical module and Optical Rendu, since Uptone now makes a competing product. Recall, Uptone came into existence making derivative products such as USB fixers and power supplies to be used with Sonore's series of streamers - the hypocrisy of it all. I appreciate that others may have had a good experience dealing with Uptone Audio but unfortunately, that hasn't been the case with me. Uptone strikes me as a bucket shop. There are lots of cottage industries and artisanal products in hi fi and that is fine and good, so long as they are run with honesty, integrity and professionalism and not at the expense of unsuspecting customers. Pete of Triode Wire Labs is a great example of a fine one man show company who provides great customer service. Uptone is definitely NOT - YMMV!

Hi, I'll bet I'm not the only one on the site with both a mRendu and a REGEN. Of course I've thought about selling the REGEN but tinkerer that I am I just had to try cascading the mRendu into the REGEN. Here's the setup: Blue jeans Ethernet > urendu powered by HDPlex > short supple USB from Uptone > REGEN > Clarus Crimson USB into Lampi DAC. I thought using this chain over the top. But had to go out of town. When I returned my REGEN had failed. (Uptone quickly replaced it.) And my HDPlex 100 watt linear power supply died as well (new one on its way) so haven't got a chance to listen again. To me the system just sounded more powerful and robust. REGEN and lpsu on the way back. But meanwhile have a chance to purchase Curious Cable loom. Here's a couple of questions I'm pondering. I'd sure like some input. 1. Has anyone else tried this? The results? 2. Curious cables question. It seems that some people have not found using a Curious Cable REGEN link (or any other expensive USB cable as well, not trying to pick on the obvious great cables built by the Curious guys) to make much difference between the mRendu and their DAC. I'd be glad to see feedback. MRendus should be broken in by now so could I get some feedback on this? (Yes, I've read most posts already but they seem older with nothing up to date.) 3. I'm considering purchasing the Curious Cable Loom to connect the two? I'd sure be glad to hear feedback before I buy. I'm always ready to talk about audio. If you'd like to discuss experiences PM me and I'll send my phone number.

Hi Everyone, I'm thinking of getting the U-DAC8 ($250, the only 8ch USB DAC under $3800) for my HTPC and buff it up with goodies (up to ~$1500) which I could still use when a better option for a DAC would come along. Thought it would be fun as a project to see how a low-end DAC could benefit from high-end PSU and USB interfaces. Options I had in mind: tX-USBexp (sPS-500) --> U-DAC8 (LPS-1.2) - $1,250 PC --> tX-USBultra (sPS-500) --> U-DAC8 (stock) - $1,685 tX-USBexp + sCLK-48 (PC PSU) --> U-DAC8 (LPS-1.2) - $1,477 other? What do you think?
