Did you compare the Plixir to one of these: https://www.custom-hifi-cables.co.uk/power-supplies/dc3-power-supply or these: https://www.custom-hifi-cables.co.uk/power-supplies/dc4-power-supply
I compared to an older DC3, but Sean Jacobs has stated that he has made multiple improvements since the original was released. It wasn't a fair fight, TBH.
Also tried a recent SR4-T and SR7-T. Plixir bettered the SR4-T and traded blows with the SR7-T. Plixir was better for me as it sounded bigger and's more tonally fleshed out, but retained the attack and resolution. SR7-T sounded a bit more open up top, but this was subtle. It also sounded thinner and had a slightly smaller and less-focused soundstage. However, this is going to be system dependent at this point.
I would expect the mighty DC-4 to be better in literally every way... and likely not by small margins. As it should, for £4800 including VAT or $5400 USD.
UPDATE: the Qutest sounded radically better with both the Plixir and SR7-T.
And, like the DC-4, the Plixir Elite BDC is also doubly regulated. The Elite BDC, in addition to the double regulation, uses a toroidal transformer that is wired for balanced power (+60v/-60v here in the US), which itself assists with noise reduction.
