I have Spendor SA1's and have owned SP1's. I am a big Spendor fan. The SA1's, which I use in my BR system, are terrific little speakers, with more life than the SP1's and unbelievable soundstaging and imaging. Vocals are eerily natural and realistic. Bass is not very deep but you will be shocked at how tuneful and accurate the bass is. They need power (I would say at least 100 w/ch and good cables. The best compliment I can give them is that I have forgotten about them.
