Yes, we had a few for some special projects. These were left over. They do sound quite good, very powerful and free of grain and glare, can drive most anything. They won't conquer the world and solve world hunger as some seem to think though. At Rich's GTG the amp really made the Legacy SE's come alive IMHO.
There are a lot of competitive amps out there, though at the $1-2k price point these are hard to beat. Their real utility shows when using the "hanger" modules which support bi-amp, tri-amp, etc using the existing onboard power supplies. Very cost-effective options for oems. Hypex has similar capability as well.
Note that soldering wire into a JST terminal, especially more gauge than is intended to fit will mechanically weaken the connection right at the end of the solder joint where it ends on the wire. That becomes the weakest point and may break. It's just a bad practice so I choose to avoid this. If it breaks, it doesn't matter how much better it sounds.
