I’ll take system synergy over measurements any day. I will take my ears over any measurements. If a speaker measures good, what does that mean? What amp did they use? A tube amp? A set? An analytical sounding amp or a warm sounding amp? There are some speakers that might measure well but I wouldn’t own them unless I had the warmest sounding amp, or I wouldn’t buy a warm sounding speaker with a warm sounding amp.
The biggest thing for me is to get a speaker sized right for your room without the need for extra room treatments or dsp to tailor the sound. I moved from a larger dedicated room to a medium size room 16’ in length. I had a very nice sounding larger speaker and even with using dsp and several super bass panels, the bass was overwhelming. In all of the audio shows I’ve been to for the last 25 or more years (ces, the show, rmaf, Tampa, and many others), the best sounding speakers have always been: revel, usher, raidho, Wilson, and totem.
I would have loved the Revel Salon 2 or Studio 2 speakers, but the bass would have to be tamed by panels or dsp. So I bought the newer release of Revel BE with the smaller woofer speakers that allow me to remove all the bass panels, still kept the ASC tube traps for corners, I stopped using dsp, and allowed me to get the speakers 1/3 of the distance into the room to get all the bass I need without using subwoofers.
