... I like that Peter throws down the gauntlet with the P4 monoblocks "The end result is a circuit with 3 transformers, two super linear Directly Heated Triode gain stages and two Audio Note™ 2 watt tantalum resistors in the signal path, with no signal capacitor in sight, try improving on that for ultimate simplicity!

Actually, he was asked what those advances since 1960 were. You have chosen to imply that there was an actual subtextual element to the question.
The subtextual element was there at the beginning of this discussion, when the price of these uber expensive amps was called into question.
Yes I did ask about advances since 1960, since Newman made the "advances in 50 years" statement. To my mind toroidal xfrmers and using SS devices in tube circuits are hardly earth shattering and certainly not worth $600K.

You're still trying to rationalize 'worth' in a concrete, logical, physical sense. That has nothing to do with why people buy something like this.

Why dont the moderators closes these threads anymore?
The cost no object projects are subsidized by the uber wealthy.
I've gone faster on Delta. And got free peanuts.
The less-limited use of toroidal output transformers,
I'm not sure that I brought up advances in technology. Others were insinuating nothing has changed in the tube world. The performance of modern tube amps says differently. I'm 100% with John on this one. The additional worth isn't coming from the significant performance improvement that some modern tube amps offer vintage ones. I just found it a bit of a stretch to think that nothing has improved.
You say that the "...additional worth isn't coming from the significant performance improvement that some modern tube amps offer vintage ones."
I would contend that just because someone wishes to pay these uber prices does not make them worth that much. There is sometimes a great disconnect between what something sells for and what its worth. Selling price is clear and simple, its what two people will agree on for an exchange of goods and or services for a defined payment. Worth is not so clearly defined.
Perhaps an example would help. I just looked at recently closed auction on the Eico HF-81. No matter what your opinion of that particular amp is, we must agree that it is generally well thought of out there judging buy how well they sell on EBay. The current crop of closed listings has them selling between $200 for non - working and $550 for fully functional ones. There was one that was listed at $700 that did not sell. I remember some time ago one of these little 12 watt/channel amps selling for $1000 on Ebay. So, is the amp worth 550, 700, or 1000. Or only 200? I certainly don't think its worth 1000 even though someone with strong desire and more money then sense paid that much for it, but perhaps it is worth in the neighborhood of 450 to 550 since several examples sell in that range.
My point is that selling price does not equal worth.
