I had dna1 with rev a mods long ago with Vandersteen speakers. All I can suggest is what I owned with DNA. First was Rouge 99 magnum, BAT vk 5i se and Don Allen preamps. My favorite was the cheapest which was Don Allen, they pop up every once in a while in $500 range used. The Rouge was next with top end NOS tubes. The bat just never seemed to match well, maybe because it sounded more solid state than others to my ears.
