I have had the Sierras for about a month now, up until last night I had them hooked up in my HT. They sounded very good, I flipped back and forth from running large and no sub, to sub and small, all the time I was very pleased with the sound.
On Saturday I got my mcintosh preamp back from being restored, and hooked it up to a mcintosh 2105 amp, and an onkyo cd player. The difference is stunning. This is my first foray into a dedicated 2 channel setup, I am just blown away by the sound, imaging, and detail. I am running the sierra's without a sub and amazingly do not miss it in the least.
Thanks again Dave for putting out such wonderful speakers.
Peace,
Jim
