I do actually own a Naim product, a CD5 player. It was coming without the jumper needed if one did not have the external power supply (which I don't, and don't intend to), and so I ordered a 4-pin DIN plug and soldered jumpers to it to make the appropriate plug. When the item arrived, I noted that the seller (a company that restores and sell vintage high-end audio equipment) had bent a couple of pieces of solid-core copper wire into U shapes and stuck them into the socket to jumper the internal power supply to the audio section. I thought about removing those and inserting my plug. I thought about it for about 2 seconds. The wires are still in there. Of course, it's oxygen-free copper (that's my story and I'm sticking to it.)
The reason I bought it is not because "there be majick". The reason I bought it is because it uses a simple and reliable Philips transport that is mounted on a manually operated drawer that rotates out from the front of the case, leaving the top of the unit free to hold something else, and eliminating what has for me been the least reliable part of old CD players--the drawer apparatus. It uses a magnetic puck to clamp the center of the CD onto the drive hub, and these are readily available and not too expensive.
Sound-wise, it sounds to my ears exactly like my other CD player, a Cambridge Audio CXC with a Topping E30 DAC. Both sound superb, as one would expect from a reasonable-quality CD player. I think it might roll off the very top part of the top octave very slightly (based on old Stereophile measurements), but I can't hear that high anyway.
Looking at the Naim, I see a high-craft (if not high-aesthetic) case, quite robust mechanicals, very good circuit construction, simple controls, strong serviceability and maintainability, and a remote that uses a standard protocol (Philips RC-5). And they didn't do anything to undermine the sound.
