Hi @mikhailark , On my speaker buying adventure a few years ago I heard both the D48 and the K6 from Proac. Very nice. Bottom ports I believe so bass was impressive and highs silky smooth. I had Vandersteen Sig3a's years ago and they did not do it. I passed on Magico, Kef Reference, Sonus Faber Amati Tradition, and Focals in favor of Revel Salon 2's (used). They are getting to be a bit of an older model, but they do nothing wrong and everything right. The Studio 2's are great for a smaller room, but the Salon 2's fill a big room beautifully. They do like power. And I like sealed speakers vs ports, fundamentally. You see them now for under 10k for the Salon 2's, a steal. Good Luck!
Non-fatiguing speakers in $10K range?
Some years ago I downsized to headphones only. Now I have access to a dedicated room again, so getting my absorption panels and ASC Tube traps back from storage... :-) The amp is going to be Accuphase E-800. I like class A, and I owned fair share of Pass gear but Pass integrated (and lower preamps) no longer have tape loop. I also like my gear to look the way I enjoy and Pass went too industrial for me.
Anyway, long story short. Speakers. I prefer relaxed, non-fatiguing sound. My headphones are Meze Elites and I love them. I also own Focal Utopia, but rarely listen to them, too forward for me.
Now, music-wise I do not listen to jazz or classical or vocals, sorry. Classic rock, hard rock, 80s new wave, punk, pop (classic and modern) and African blues like Tinariwen. People tend to insta-suggest forward sounding speakers - you like metal, right???. But I don't like piercing sound and I rarely go to concerts exactly because of this. I listen to AC/DC but NOT at 'realistic' revels. I like rhythm, melody, but I don't care about 120 Db.
The budget is about $10K, give or take, most probably second hand, but I can buy new, if I really like it. Unfortunately, there are not that many high end shops around Seattle with gear I like. Some went selling vintage and some went up selling only $100K+ systems. So most probably will be getting something blind.
It seems I should be looking for ribbon tweeters, I spent hours at youtube - it is definitely not listening in person, but some recordings are pretty decent and many show differences between speaker models.
I also compare frequency response measurements - I can easily tell that I won't like the speaker by looking at the chart. Ex, bump around 2-6K is a no-no since this is what "bright" is. Dip is actually good since this is what makes sound less "in your face/ear".
So far I more-or-less narrowed my search down to Legacy (Signature or Focus), Dali 8, ProAc (D48 or K) and - maybe - Magico A3? Legacy is huge, I am not sure I really need 20Hz extension. Magico has beryllium tweeters which may be bright....
I purchased Tannoy D700 many years ago, still own them, they are part of my TV set up. They sound good, but not as good as I would like it. My desktop speakers are ribbons too - AirPulse, I like them quite a bit.
Anything else I am missing?
