For a four banger it has to be a flat four for sound quality. However only above about 1500 rpm's. Below that and they all sound like
Beetles.
It must be the offset firing order with the slight pause between the pairs that makes it special. If you can get them to rev high enough it is just
music! Hence the Alfa Sud as one of the best ever sounding small cars.
All in my humblest of opinions of course!

I've always hated the flat-four throb - always sound like they've dropped a cylinder. otoh, a Subaru WRC at full noise sounds superb
Always liked the DOHC Chevette HS2300 (but then it's supposed to be half a small-block Chevy )

Does a 4-plate Rotary engine count?

3.0 Alfa V6
My brothers pride and joy is a 1998 GTV 3.0 V6 that we took to Le Mans last year. The sound through the gears all the way to 140 from the toll booths
was spectacular. The whole car feels highly stressed all the time, even just pottering about the engine is straining at the leash. I Can't see
how these engines last more that 50k miles!
A friend had a Clio Williams MK1 that was standard but for a K&N filter. The engine sucked so hard it sounded as if it was supercharged!
Also had a blast from the past last week when a BMW E30 2.5 Sport hammered it past me on full song!

V10 eh? that's cool. 
Would I be correct in assuming that most of the engines mentioned here are of the 10:1 and above compression ratio? The thought being that the hi-comp
engines make a much lovelier bark than the low comp ones?

Yea, most are higher compression, BUT!
Most of the lovely noise is intake not exhaust, and is down to cam timing+individual runner induction per port!
If you listen to the "Mancona" on the first vid I posted, all you can hear as is comes towards you is induction noise, it's only
once is has passed the camera that you can even hear the exhaust at all.
Retro RWD is the way forward...........automotive fabrication, car restoration, sheetmetal work, engine conversion
retro car restoration and tuning

An alloy flywheel makes a difference on the sound of throtle blips. So you get that nice idle to redline and back to idle in a partial second.
