He recommended Transcendence 8+ vacuum tube preamplifier with Insight+ 240 solid state amplifier.
I too am running this same set up with "stock" ST's (Hiquphon OW2 tweeter) for about a year now. Most of my listening is computer audio (.flac files) via a SB Touch (un-modded with TT 3.0 tweaks). You will LOVE this combination!
Two of my favorite aspects of this rig are the lack of fatigue (already mentioned) and the ability of the AVA-Salk combo to capture the signature of recorded, live music. I already mentioned in a review of my ST's that I listen to A LOT of live music which is taped with microphones in the audience (not soundboard or official releases, etc.) and it is uncanny how the warmth of a small club or the airiness of an outdoor venue is transmitted into my living room.
But perhaps my favorite comment about this system is one from my wife. She arrived home from work shortly after I received my AVA gear, sat down to listen to some of her favorite tracks, and exclaimed, "It actually sounds better, louder!"

Sufficeth to say, I don't have upgraditis with my pre-amp, amp, and speakers. I just need to get my sources up to par.
