I've given the Quattros a good break in and I've got to say that these
are some of the finest speakers I've ever heard. If I had to
use one word to describe the sound, it would be "detail." The
sound is very clean and new details are heard on recordings I have heard
many, many times or were so much less apparent on lesser speakers that I
never paid them much attention. These details are creating a whole
new listening experience requiring old albums to come of the shelf "to
hear what is there." For example, I put on Gerry Rafferty's "Right
Down the Line" and discovered the two-different wood blocks and triangle
that alternate from right channel to left channel throughout the song.
I knew that sounds were part of the song, but now it was as if the two
percussionists were standing directly in front of me taking turns
measure for measure. These details are simply more "present"
than on other speakers I own -- even my Gallos, B&Os and B&Ws.
The build was a very enjoyable endeavor and to come away with this
quality of sound makes for double reward for my efforts.
Here is a photo of one of the finished Quattros. The stand was
made from the non-rotted pieces of red oak plywood that I took of a
trailer that my engineer/father built 40 years ago.
