As I used those phrases, I'll assume that means, or at least includes, me. As I said, it's entirely subjective, so those phrases are supposed to be descriptive rather than definitive.
Which meatball recipe is "better", and which do you prefer? Is a John Lewis suit better than an M&S suit? Is a BMW M3 better than an AMG Mercedes?
On what criteria do you judge?
As with the above, I know what I like and don't like, and often, which I prefer over the others. But "defining" why is much harder.
For instance, some years ago, I compared the M3 to AMG Merc (and a bucketload of others, from Lotus Esprit Turbo to 911 Turbo, from XK8 to DB7. I bought the M3. Why? Because I liked it.
Oh, I could give a long list of factors, from style, to performance per pound, to value for money, to mix of practicality and performance, but at the end of the day, I just liked it best. Then, a few years ago, I contemplated a new one. I didn't even get as far as a test drive. I sat in one, and that was enough. No sale. It felt like I was sitting in the Black Hole of Calcutta, dark, dreary, enclosed, almost claustrophobic. Not, to me a pleasant experience.
A week or two ago, I tried the new one, well, M3 and M4 to be precise. Now I'm torn. It's much better than the last one, yet still, not sure. The external appearance is just .... a bit bloated. It looks .... aggressive, but one of the things I like about my old one is that it really doesn't. You've got to look quite hard, or know what you're looking at, to realise it's not any vanilla 3-series. But the new one is just somehow .... pretentious .... in styling. It's as if BMW adopted some of the worst show-off design style of Japanese pocket rockets, and lost any pretence at subtlety or understatedness in the process.
If those Japanese rockets are brash, loud show-off teenagers, the M3 /M4 is perhaps a middle-aged man trying to be a teenager, and just not quite carrying it off, and looking a bit silly in the process. I'm given to understand they are astoundingly good cars, performance-wise at least, but I'm just not sure that's enough for me.
So the definition of "warmer" and "less clinical". I don't know, and to be honest, don't care. I just like the sound.
But here's a conundrum for you. I have two decent pairs of headphones. One, a high but not top end set of Sennheisers, are a fairly warm, full, rich sound. The other, a set of Stax Electrostatics are about as crisp and clean as headphones get (or got, seeing as I've had them since .... well, a hell of a long time). Yet I REALLY like them. The two, though, are VERY different. But I like both.
Or to put it another way, I like Renoir and Matisse, but don't like Van Gogh or Picasso. Which is better? Don't know, and don't care. I just know which I like. Just as, if I try a new meatball recipe, I know if I like it or don't but would struggle to define why, and certainly to state which was "better" than the other.
It's subjective.
