I have heard both.
Forest with Jolida, Conrad Johnson, and McIntosh. Really liked
the sound, great imaging and vocals; a tad dark, but the sound
was rich and powerful. Good mids helped with the imaging. The
highs were really really smooth (reminded me of the Vienna's,
but with way better mids).
The Contenders were a major disappointment to me. Heard with
McIntosh gear. Bass was muddy, mids were recessed, imaging was
fuzzy and the highs had no sparkle. My experience was 180
degrees different from all the reviews I read (major
disappointment, frankly).
Just my humble, subjective, observations.
