Thanks for the reply, Paul.
I'm actually asking this question for my dad. When I showed him that he may not need the preamp, his interest really piped up as he could sell that to fund the purchase of a Stereomour.
So, with the source selector and integrated volume, there would be no need for the preamp at all? Would either 2A3 or 45 tubes have enough "oomph" to give enough bass extension? The KLF-20's have 2 10" woofers in combination to the tweeter and mid horns. Or would the preamp allow the Stereomour to operate on the lower end without as much distortion as if it were on the high end?
Thanks again!
