  1. Don’t worry , the JCAT won’t disappoint. For best results, power the board with a separate 5V , 2.5A psu , sinks the noise floor down a few notches. Must try the speed limit to 100Mb/s & see what happens.
  2. The dcs Network Bridge is a Roon Endpoint, it doesn't have the horsepower to run Roon core, nor any facilities to install such an app.
  3. One of the Windows 10 updates hosed the SQ for Roon Server late last year. The SQ was dreadful, bad timing meant sound stage collapsed, and the SQ was very grainy. Tried Fidelizer, shutting various processes.. few things, difficult. Fidelizer tried but not the best like it was. The Server previously had Win2016 installed, but was intimidated a little with the OS, so felt more at home with Win10, until the update forced the choice. Researched into Linux, enough to convince me that was too hard. Bit the bullet and installed Win2016 again, this time with no multimedia extensions, DLNA media library, nothing, just a plain server. Roon 1.5 was great, SQ back again. When Roon updated to 1.6, the SQ was much the same as before with 1.5, but other operational nuisances remain unresolved to this day. The Roon message boards are full of complaints about 1.6. I feel for @Benno with Roon not working on Win2016. Under 1.5, I tried HQ player, but it could not sync properly, and if rapid changes in music was selected, the thing fell over, so removed, and stuck with 'plain' Roon, which works really well. I don't use Tidal, nor AO, so can't comment on that, tried Tidal, not for me, and AO just looks TOO HARD. Fidelizer works on Win2016, but it didn't make a difference, so it's removed.
  4. For a balanced connection, there are two lines that are above earth (180 degrees apart not quite -60V), so a single pole GFCI cannot be used. This involves a 2 pole type, like this one at Amazon. 10kA is a real overkill. seems to be the only type they have a quick search revealed, 3kA is more than enough, please find one of these, that's why the price is a lot higher. That breaker needs a proper box, glands, cable, not really an audio hobbyist venture. If you can find a double pole type in a plug in arrangement, would be better. Where one side is grounded on the output, you can use the yellow plug in job, single pole. Grounding the output neutral is important to keep the neutral at ground potential without causing the neutral to 'go high' which is a bad thing for equipment, in a small system like this, there should be less than 1-2mV difference if that between ground and neutral. Current will NOT flow in the ground (unless the HOT touches the frame or leaks to it). I use this system for appliances, and computers where balanced supply doesn't work due to the two HOTs not being switched by the appliance, like lights. It's technically a TN network.
  5. Perhaps ask @lmitche about the musicality of the RME ADi-2 DAC. It matches what my impression of the RME HDSPe AIO PCIe card.
  6. What I meant by a Hydra is one lead with an input AC male connector, cabled into a box. The same box has eight or so separate female AC connectors where the equipment is plugged into. There’s nothing special in the box, perhaps some neat bus bars to join the three conductors to and clamps to stop the cables being pulled out. Shunyata took the name of Hydra and polluted the search engines, making the original Hydra difficult to locate. Far as I know, the Shunyata gear contains very little bit much propaganda.
  7. A dedicated line is ahead of any AC treatment, many members would agree. Simple devices work the best, an old Topaz balanced out transformer with a plain power strip, or similar multiple wall outlets, from the same transformer. AC outlets should number what components you now have + 3. Avoid daisy chaining power strips and connect all equipment at the same point. Look up a Hydra as a good example alternative to power strip. Not the Shunyata stuff. AC power from the street is not dirty really. The problem is mainly on the equipment side causing the headache. Devices measuring the bad input side are measuring the effect the device is on the network. Leave to one side: Regenerators Power conditioners with caps and chokes Devices with surge suppression (fit at main panel) AC cables with boxes as part of the construction.
  8. @AudioDoctor, What’s the time period of the data in the screenshot?
  9. The Kill-A-Watt meters don't read reactive pulses very well, but they give you a within 20% in range reading as a safe measurement. The front end of a transformer pf will be low due to the loading of the transformer, the lower, the worse pf, but you aren't invoiced by the power company for pf penalties at home. The BK transformer, looks like a single winding only, with no taps. If you have two of these, and feed the primaries in series, so each will have 60V. The secondaries can then be wired 60-0-60. The rating is the same as a single unit tho. There are some tests to do, you need a DMM to make sure the secondary polarity is correct to achieve a balanced output. Depending on the symmetry, you could cancellation, but a purpose transformer with the same windings on the same core will cancel better.
  10. That’s great news! Yes the buzzing noise is caused by frequencies that are trapped in the windings with nowhere to go. By using a balanced supply, the same frequencies are cancelled, the transformer is cooler and less noisy. For SQ, deliberately listen to the silence between tracks or a very long fade out, there should be less mire and more black.
  11. Did you arrive at this conclusion after your favourite extensive DBT and with which other makes / models? Oh, 'elite aesthetic' looks very subjective, coming from you, that's new, is there a turnaround?
  12. Well.... from the same article.... Recent experiments show that 100% of listeners were able to tell the difference between using an amplifier with a power cord attached, and without.
  13. I have purchased The Lo-Rad cable from your goodselves, quite some time ago now. The Lo-Rad has copper cable which tarnishes in high humidity regions and I can't use it for audio apps. The insulation is not very easy to strip, tends to stretch using stripping tools.
  14. Furutech USA will not supply the parts to Cableco. Different story. It also involves a Euro AC power strip as part of the order. Neither will be supplied by Furutech USA.
  15. The cableco was the supplier I turned to first. The order was for a Furutech Schuko distribution unit and the cable, both items were purchased some time ago. The Furutech distributors would not have a bar of the schuko unit, nor the cable to be delivered in another country where Furutech was sold. So missed out on cableco and also local distributor who won’t stock the cable. As they say, back to square one.
