Another vote for the Loki, I use it between my source and a PrimaLuna Prologue Premium Integrated, it lets me enjoy listening to some recordings that are too bright and thin sounding. I have a very simple system and have it dialed in, great recordings sound wonderful, but a lot of my old Blues albums, specially live albums, don't. When I want to listen to those albums I flip the switch and it cuts down on the HFs and fattens the sound.
can you add tone controls to a primaluna HP integrated amp
Miss not having tone controls
