At the dealer where I compared (in the same room with speakers in the same basic location), using my Hegel 30 amp, 30 dac, and Aurender music server (and Anzus C2 Cabling)...
The Contour 60s sounded "good" and had phenomenal bass... so extended, effortless, and with "punch" when called for. However, the soundscape was "monochromatic" or to use another visual example... it was like the color was washed out and subdued. At least they sounded that way when listening to them right *after* listening to the Sopra 3s.
The Sopra 3s had bass that was articulate, but less satisfying to my ears without a sense of weight and authority (though they did go low)... that's where the Dyns really beat them IMO. But the mids and highs were glorious... airy, open, extended, not shrill or bright at all... with resolution and micro detail that kept making me wonder how anything could sound higher-resolution than the red-book CD files I was playing. There was also a lush and alive sound to vocals that was seductive... which was why I ultimately bought them.
After having them for a few months I wasn't thrilled with how they sounded in my own living space (I had a hard time getting front/back holographic imaging with them for some reason in my own house... and that's a key criteria that makes me happy when I listen to high-end audio) and I needed cash given some unexpected issues that came up.
I kept my Ansuz cable upgrades (speaker cable and power cords) that I had done at the same time I had bought the Sopras and wow... that has totally transformed my entire system and made my old (I kid you not) AV 123 "rockets" sound better-than-ever. I hope in a few years to be ready to sound-treat the room and figure out what used speakers might be available at that time so I don't take such a financial risk/loss the next go-around.
