I'm going to concur. How much to spend is such a personal choice. If I were to spend upward of 1K, I'd be inclined to put them into upgrading headphones. Well, upgrading isn't right, I really like my Grados-adding options sounds better....choices/variety....following the adage that you get your biggest improvement in HP's/Speakers. Speaking just for myself only owning one set of $200 cans, I could justify spending no more than 2.5 times the value of the cans. But, to spend $1,000 for an amp for a $2-300 HP seems a little lopsided to me. If I wanted more sound stage, I think I'd get a second set of cans....and in fact, am considering the HE 500 for that very reason.One more "polite", refined set of cans w/ more sound stage and one more front and center, bright and aggressive. And, I'd be inclined to keep -in my case-my Asgard 2 which would drive both.
Now, if you have several sets of cans ranging from say $150-1,000+ that changes the calculus entirely.
My opinions only, of course. And, to each his own, yada, yada....
I agree 100%.
To buy a $1000 amp to play $200 phones on , does not make much sense to me either.
For me personally...its....Headphones >Amp>DAC
