The best audio is both. I’ll cite a couple of examples from my own kit:
Thorens TD-124. Introduced in the late-50s and has every feature you could possibly want for playing records: all four speeds, pitch adjustment, strobe, a clutch for easy record changing/broadcast fast start, a built-in adapter for ‘dinked’ 45s (it just pops up), a built in spirit level for levelling along with easy to adjust levelling edge-wheels, arm board removable from above so you can swap arms in five minutes tops (assuming you have the next arm ready mounted on another board).
The SME arm is just as radical. That is the point easy tracking weight adjustment, bias, VTA, azimuth etc all came together with coherent design and did so in a beautiful timeless way that still looks modern (the original Series I was introduced in 1959, the one on the deck is from the late ‘60s).
Form, function, ergonomics. Everything is there for a reason, yet it is pulled off with the form and grace of a Henry Moore sculpture. It astonishes me how much we have forgotten since this time. So many modern decks are just horrible ergonomically IMO.
I’ll go back to the Leak TL12 Plus I mentioned upthread. It is a mono valve amp. Everything that it needs to function as a mono valve amp is out on display in a totally honest, yet aesthetically pleasing manner. Mains and output transformers, smoothing capacitor and valves along with an input socket. 100% form dictated by function, yet it doesn’t look like a piece of lab gear.
The underside is an object lesson in good logical electronic layout and long-term serviceability. It comes with a schematic in the manual and is the very definition of ‘Right To Repair’. This is exactly what good design looks like. I can’t imagine much if any of today’s kit will be serviceable in 60+ years, let alone as desirable as either of these items!
