Thanks re: the input value. I have a 7.1, would just like to get a better pre amp (there's a Primaluna for sale where I am)
There's various ways to measure impedance. I am afraid of blowing up something if done wrong.
Alta Vista NP-100 input impedance?
I'm looking at a Primaluna pre amp to run my pair of Alta Vista NP-100 (UG'd Counterpoint SA-12s). It appears that the PrimaLuna works best on high input impendance (~28k Ohms?) power amps. I have no idea what the impedance on my amps are or have the tools/knowledge to calculate such. I do know the P-100s are the low sensitity ones (use 6SN7s instead another tube). Pre-amp being replaced is a Counterpoint SA-7.1
