Have to get my 2 cents in.I'm using Innersound EROS 3 Electrostats and the AH is an excellent match,the bass is tight and well defined.It should be a seamless integration with your Logans.
I concur with others on the Siemens tube recommendation.Of course what do I know,having thought I found the pot of gold
I was using a quad of Russian super tubes only to be advised by my good friends here and confirmed by Joseph that the AH is not compatiable with them.I still owe a round of drinks.But I am a really smart guy when you get to know me.
