Sometimes I feel amp builders, in the race to create the tightest tube amp possible may sacrifice too much richness, warmth and body to get such immediacy and tightness. I always think of these tradeoffs in ratios. Maybe amp A is tighter than amp B by a little, but to get that extra bit of tightness, a whole lot of warmth and more pleasing frequencies were lost. Sometimes the tradeoff isn't worth it. Just my perspective.
