The guy who is electronics design director at NAIM is called Steve Sells. Way back, I recruited him from University into Cambridge Audio, when he was already a power amplifier designer of some capability. After a short while, we moved that into Wharfedale, where we planned to re-launch the LEAK brand. I asked him to design the best power amp he possibly could, price no compromise. I told him that we had to out-Krell Krell, and if he felt that silver wired mains power transformers were essential, he could have them (he didn't - phew!). This was a superb animal, balanced input, bridged FET output monoblocks that would push 800W into 2 ohms, each with three mains transformers (two huge ones + and - for power transistors, and a single higher voltage one for the input amplifiers).
Fast forward three decades, and NAIM told him the same thing, best possible no holds barred - Statement was the result. Not for those with less than seven figure salaries. An awesome audio tour de force. Have a look at this:
