Amp design logic


I hope you'll excuse my absolute and obvious ignorance...but this is a sincere question.

I don't get why one company is selling a new tube amp for ~$1000, and another is selling one for ~$50,000. What is one paying for? The proprietary circuit design?

Surely if one adds up the cost of the parts, trannies, chassis, etc. it's not worth $50K.

I accept that the more expensive one sounds lots, lots better. But what makes the price so high? Demand?

I think given a circuit diagram from a repair manual, I could eventually build most tube amps from scratch, using the absolute best of each part available. After I learn to solder. For less than $50K, just buying the best cap, resistor, wire, etc. made, for each part, I could slowly build an amp equal to the best in the world. So I don't get it.

What makes an amp worth $50K? It can only be the proprietary tube amp design.

Maybe another factor is the transformers. Each company seems to have their own iron, but that can't be a significant part of $50K?

Thanks, just really wondering about this. And wondering why don't I just make my own? If I buy one part at a time, eventually I can have the best amp there can be.

Here are the questions...

1. Between a 1K amp and a 50K amp, what accounts for the additional cost to the MANUFACTURER?

2. Between a 1K amp and a 50K amp, what accounts for the additional cost to the CONSUMER?

3. What is more important to the sound quality of an amp: its DESIGN or its IMPLEMENTATION (i.e. internal components)?

Here are my suspicions...

1. It depends on the amp.
2. It depends on the amp.
3. It depends on the amp.

RE: 1. Every manufacturer has costs, but not every manufacturer has the same distribution of costs. To state the obvious, there is considerable variation from company to company in the number of employees, the extent of marketing, the R&D man hours for any particular model, part costs, the costs associated with a particular country (labor, building, shipping from factory to market, monetary exchange rates, etc.). My suspicion is that there is significant similarity in the distribution of costs among manufacturers of $1K amps, but considerably less similarity in the distribution of costs among manufacturers of $50K amps.

RE: 2. Cost to consumer = answer to #1 + profit. With respect to profit, again I believe that there is considerably more similarity among manufacturers of $1K amps than manufacturers of $50K amps.

A consequence of #1 and #2 seems to be that there is considerably more variation in the PRICE/VALUE ratio for $50K amps than for $1K amps, which seems consistent with audiophiles' experiences.

RE: 3. There are several people on this thread who have far more informed opinions than I do, but from what I can tell, the relative importance of design vs. implementation (i.e. internal components) to sound quality varies from amp to amp, and probably from amp type to type. And I suspect that the relative importance of design vs. implementation varies among sections/stages OF THE AMP ITSELF.

I also suspect that the attribution of sound quality to design vs. implementation is highly speculative, except for manufacturers who have personally built many similar versions of the same amp over a number of years (e.g., Nelson Pass, Ralph Karsten), and so are in a position to have heard (a) similar designs with varying implementations, and (b) varying designs with similar implementations.

And finally, there is a level of analysis at which the distinction between design and implementation breaks down, but that is a bit of a philosophical quagmire.
