Hi Grant,
From a price comparison, it wouldn't be a fair comparison, however, a couple of guys have said that their TP 2.0 versions sounded better in their systems than a couple of preamps that retailed for $16,000.00 plus. I would love to hear your impressions of the Atma-sphere preamp paired with your VAC monoblocks, though. Are you getting a nice sound through your speakers that you're happy with?
