I've seen several comments about "gold" or "bronze" colored Pioneer SX receivers from the "silver-face" era. I've collected quite a few SX-424, SX-525, SX-626, SX-727 and SX-636 units over the last six months (refurbishing them to compare to my HK 330B's and pick the one I like best, then sell the rest). Since there are only a few pictures of the bronze or gold toned silver-face units here on AK, I thought some of you would like a few carefully-photographed, post-cleanup, no-nicotine-coating images of the differences. Here are color-corrected images of a silver-face SX-626 side-by-side with a gold-toned or bronze-toned SX-626. These images were: shot with both faces in the same plane or angle to reflect light similarly, and illuminated with three, identical-temperature photo florescent bulbs to eliminate multi-temperature errors, and captured with a flat, white-colored card to allow them to be color-corrected in Photoshop, and then described with a whole bunch of technical-sounding words to make all this seem more impressive.
