1. Keces P8 PSU plus custom umbilical made by Ghent Audio. Ghent makes excellent cables, and he is fabbing one for me with a 2.5mm tip on one end for the Keces, and a 5-pin Neutrik XLR on the other for the Wavelet. We’ll see how that works; I like Keces, and have good success with them powering a number of devices.
2. Plixir Power Elite BDC, with custom umbilical cord. James Soh there is very helpful. I’ve been looking forward to trying a Plixir product, and while it’s not the balanced power supply I thought I would first try, this is a good start. Their products have received some very nice reviews. James features several use-case-specific versions of the BDC on his website, and I have suggested he list one for the Wavelet as well. Given our hobby’s obsession with improving every last detail of a system, I would not be surprised to find other Wavelet owners interested. And being able to source this option from one vendor, as opposed to two, might be advantageous.
3. HDPlex 300W PSU plus a custom umbilical made by Revelation Audio Labs. This is the combo in zephyr24069’s system. Brad Vojtech of Revelation is superb to work with. Some—though probably no one here—might find his cable is a tad pricey at $349 for 1.5m. Unfortunately, I have never been able to purchase an HDPlex PSU, though I have tried at least 5 times over the past couple of years. They have always been out of stock, and when they have become available, I have already found other solutions.
Anyway, I hope this helps.
