Good morning. Thinking about pulling the trigger on an Ecko EV55SE integrated amp. I am a tube newbie. Have heard tube amps and enjoy the sound. This amp can toggle between triode mode and uL. I will be using as mains either a pair o Revel Concerta m12's or my open baffle betsy (which is where the triode might come in handy). My gripe with my current NAD receiver is the midrange. Smoother would be better. Has anyone had experience with the Ecko amp? Has anyone tried full range drivers with a triode amp? Thanks for any input.
