Sound stage

I've forgotten how to figure out the impedence for the old Dynaquad adaptor. I'm using Ohm Walsh 2 speakers (4ohms) in front and old Spendor 8ohms in the back. Talk about soundstaging, but I've wondered what kind of load this is putting on my B&K ST1400 amp. It seems to be working without any problems.

Answer to GregP: The Dynaquad has a pair of 10-watt 2-ohm resistors (I can't remember, maybe you should open up the box and look) that go into parallel for the "null" position of the front switch, and then bridged with the rear speakers in the quad position. In any case, you're looking at less than 3 ohms. If the amp doesn't get too uncomfortably warm to touch, it's OK, you have over 220 watts at that impedence. But why bother? The Walsh driver creates it's own ambient surrounding, why degredate the sound by using the never-were-too-good Splendors? I would put all the power to the front and turn it up 3 dB!

Thanks, Fotopres, and you would be right about the Ohm Walsh speakers and ambience, but they sit in a large and pretty dead room. I don't think that two speakers are enough in such a sound swallowing place. Digital processing didn't somehow feel right, but old Dynaquad usually does the job, and it's my favorite word, cheap. The Spendors work fine for ambience, though their sound is not as effortlessly "soundstagy" as the Ohm Walsh or the Spicas that I have.

About sound stage: The bigger, the better. Can you see the musicians? Do you feel like you are in a different room? Does the sound appear to be coming from the speakers, or from invisible musicians?

I have a Chesky Ultimate Demonstration CD that has commentary between the tracks to tell you about the recordings and the sound. Very helpful for this kind of analysis.
