Would like to add that this has been a useful thread for me. I am running a pair of Granite Audio 860.1 tubed monoblocks into Equation 25 speakers and had been using the 8 ohm tap- never gave it much thought. The speakers are 6 ohm. Tried the 4 ohm last night and was very pleasantly surprised- cleaner, more articulate bass, and warmer midrange, without losing too much on top- just the effect I have been looking for with mixed success by trying different cabling.
Are there any technical reasons that a 6 ohm speaker should be driven better with a 4 ohm than a 8 ohm amp?
