Hello @amboguzzi, If the A3 is significantly better than the A2 it must be amazing, but is seriously more money and now you are comparing to the Boulder etc. +1 @ghdprentice on the Luxman. Maybe I did not hear the right one, but it was thin and harsh in comparison to the Soulnote and the Pass I have heard. I am running my Soulnote with an iFi Nova power cord, Zafvino interconnects, stock power cord on the Altair, and basic 20 year old copper speaker wires. And it still sounds good! There is something special about the Soulnote. It is full and sweet yet still very resolving.
