"At the same time, my experiment indicates that you don’t need costly speakers to improve the sound. Much can be done with the speakers available. My guess is that many here at Audiogon would re-discover their LP collections (or streaming), if they worked more with the speaker positioning and other acoustic control. If you position (and maybe damp) your speakers right, you will get a richer and wider timbre. This is an overlooked dimension I think. Forget about exact flat frequency, timing, PRAT etc, - instead, go for the timbre. Not sure about this - but maybe a way forward."

Yes, I’d also say positioning really matters. My Tannoys sounded heavy and muddy when placed on the floor. I was so disappointed that I began to doubt my sanity in buying a 1970s speaker.
After a few days, mainly to avoid the prospect of selling them on, I tried placing them on some IKEA benches that served as stands and this helped the soundstage enormously.
The last mod was to put some sorbothane under the feet and this was another jump forward in sound.
Suddenly the bass began to play notes!
So I’d say it matters, in fact with some designs it’s more or less critical.
When it comes to good timbre though things are not so clear as I've heard some quite expensive speakers sound "bleached out" and at the other end I've heard good timbre coming from some TVs and iPads etc.
[The last speakers I heard that had good timbre were the Kudos Titans].
