Would This Amp Be Worth The Cost?

No doubt a fine amp. Consider

Simply amazing. 

greywolf  As far as pure stats go, not one spec you cite beats my 30 plus year old Audire amps and preamps.  ERGO:  That would not be the reason to change.  I would certainly presume this amp sounds better than my relics, but I did have some very fine Classe amps and preamps given to me, and they were not as good sounding, not because of any specs, but because of a feeling of the sound being artificially faked to spread out everywhere.    Maybe you should just enjoy the music. 

greywolf  Upon a bit more pondering, I don't think those are not even good specs.  The THC is not even with a full range signal, and double my Audires. The frequency respoonse is down a decibel at 20,000 cps, vs my 1- 100,000 cps that is flat to well over 25,000 cps.  I bet the Classe you have is better, at least on paper.  The signal to noise ration is nothing special, being a full 10 db worse than the 30 plus old Audires, and more akin to an almost 50 year old Phase Linear.  It may sound awesome, but not because of those specs.. 

Specs are like the ingredients list in a recipe. They are just the starting point.
Give 3 different good chefs the same ingredients, and I guarantee you'll get 3 different tasting meals with 3 different presentations.  

Hmm,

even on YouTube I feel there is a pretty clear difference in these two...
