Which components are "stupid good"?


Which components, known to be outstanding in their category, have a performance to price differential such that they can truly be called "stupid good?"

Very surprised by the performance of a pair of Silverline Prelude Pluses.  Bought new for under $2K.  Wasn't expecting them to sound as good as they do.  I think they deliver performance comparable to speakers 2-3x their price.    If not "stupid good", then at least "crazy good".  
Raidho, Magico, Aurender, Air Tight, DCS, Clear Audio, Nordost.

Stupid Good.
