Damn Martin those look quite nice!. I use old transformers from old amp preamp projects and I have a couple of heavy cast metal shielding cans I put them in. But those do look almost expensive. Here is a tip for all you folk who do contact enhancer, especially GCE!. Have you taken apart your power cables. I have 4 pair of ones that were built and it dawned on me. " I have done the blades on plugs and equipment and the IEC females with the small tools that come with GCE! But GCE makes a difference on every removeable make and break connection. So i took them all apart and GCE every screw clamp connection internally on evey male and female plug. quite a noticeable difference in noise floor, black background, musical flow and even a bit more detail. Sounds more analog, definitely improves tone and harmonics. Bass a bit fuller, slightly better texture, highs are slightly airy but less hard and bright particularly on brighter recordings that tend to get just a bit hard, almost like I got another 1.5db of gain at the same volume settings. Uncanny!
Okay yanked all the computer power plugs. I have a modular EVGA 650 Platinum I barely utilize. So fans never come on. I have cheap silernt power supply as a result. I just GCED all the plugs into the supply and all the plugs to the board...pin by pin on the blocks.
Just fired it up again. Holy smokes. Just as big or bigger difference all over again. I may have to yank the cpu and memory sticks at some point. The heat sink makes memory access impossible. But can u imagine what might happen if you GCEd the CPU chip. That could be ground breaking! If you run a computer you should do this. GCE everything. You will hear it!
Happy listening,
