Late to this thread, but based on my love of the QLN Prestige 3, had to respond for anyone considering the brand.
To the point: the QLN Prestige, in my humble opinion, is a wonderful speaker. It’s a little laid back, which makes day long listening sessions a joy. I’ve auditioned Spendor speakers, but they never connected with me compared to the QLNs.
I know many on this forum have that appetite to upgrade and chase that “perfect sound” as illusory as that obsession is, but I have zero desire to seek another speaker, ever. Amps? Dacs? Music servers? Speaker cables? Absolutely.
