Finally I found the time to go to the shop and listen the golden ear, both the 7 and the 3.
My personal impression
- 7: very good low frequency, perfect and clear for guitars/classic/Norah Jones/etc., but when an electric guitar or some electronic music enter I don't like them at all. I think the highs are a little "muffled"
- 3: better on the noisy music side, but without good bass like the 7. Still, on anything not acoustic the sound become unnatural and confused
In the same shop, the Opera speakers (~10k for 2) were available, and I tried them just for fun: of course very good on all the music, but the low frequencies (computer made) were completely absent.
Same impression with the RF 7 (in the building there is a Klipsch vendor, where I go for a quick benchmark), despite the bigger drivers
The RF 82 II sound similar (lower level) to the goldenear 7 on the acoustic, much more better on the electro side but I don't like the sax and high tone woman voice (Shakira, etc.): very metallic
I just meet a sound engineer by luck, that I kill with all my questions on why I can't find anything that I like. I understand now.
My final conclusion is that, with his support, I will try to project a full-tone-coverage towers. Still don't know if what I want will stay inside my budget, but paper is cheap and make the project first will give me a cost image
I think you will see me soon in the DIY thread
thanks to all for the support!
