Holidays, and I got sick – sorry.
I will share my thoughts on what I would do if I listen to SF Cremonese loudspeakers.
I’ll use A-75 power amp. If everything has been done for good acoustics in the music room, I would try to catch the last decibels using DG-68 Voicing EQ. If I decided to go further, I would go to listen to high sensitivity active audio system.
The structure of the system in our business is the main factor, so I would not spend money on “quantitative” changes; bi-wiring, passive bi-amping, or A-300 instead of A-75 are “quantitative” changes. The process is attractive, but there is no hope for great success.
