Agree with Sardonyx.
The amp manufacturers are mainly businesses, some are hobbyists , some are somewhere in between, most are lucky to work in a field for witch they have passion. However the "cool factor" of doing something you enjoy doing wears off in any profession.
I used to want to do my job for free, because I thought it was so cool, but now, I make no concessions to my salary because my job is "fun".
Cool pays for exactly 0% of the bills.
Business is business no matter how enjoyable.
So, you make the product you want to make, cost be damned, or you make one that will yield the results you want sales wise, with sacrifices.
Dream products are expensive because they sacrifice nothing, except affordability. They have it all, from looks, to sound, to component pedigree. Precision machined metal, sleek form, exotic tubes and transistors and so on. These are "the expensive ones".
"Affordable" products have to chose, if they reach an intended lower price point, they can no longer have it all, no "over sized toroidal transistor" or "Sophia princess tubes" or laser etching on the chassis, etc. They hit the points important to the intended demographic (budget minded consumers), and that is where they stop, because anymore, and the bottom line would be compromised.
Then there is the question of
"what is cheap, what is affordable, and what is expensive?".
This is completely subjective and relative to the buyer, the defining numbers only relate to the individual or the market, but are not absolute in any way shape or form, and vendors know this, and have it in mind when going to the drawing board for a product. They really don't care that a college student can't afford their $5,000 amp. They are looking for the rarer big spenders.
Cheap amp manufactures don't care that the esoterics look down upon them, because they are selling them in bulk, the product is not meant for them.
Cheap is the amount you find trivial and below your standards, or does not offer that which you desire.
Affordable is the amount you can spend, and with which you feel that you receive a good value.
Expensive is precisely the amount of money that you ought not spend, or for which you must give up something else to obtain.
Too expensive is the amount that you cannot spend. It is beyond your means.
The Schiit Lyr for me was
cheap. I wanted something that can do more, and I can easily afford to do so.
The Burson HA 160D, was not expensive for me, it was
affordable. It was well within my allowance for my hobby, and what I think is a good value. Though for many, $1,250 is expensive.
The Cavalli Liquid Fire for me, is
expensive, I ought not spend that much, that much "leisure money" spent takes away from things like other leisure activities. However with it's charms, performance, etc, I have been persuaded to make some sacrifices so that I can make it happen. $3,250 for me is a healthy chunk of change and I feel the financial reverberations in my bank account, and it influences whether or not I "want fries with that". But it doesn't break the bank.
The Headamp Blue Hawaii, for me, is
too expensive. I cannot justify that much of an expense. It would endanger my ability to function financially, to pay my bills, etc. I can rationalize it as being a rip off (poor value), inferior, overpriced, blah blah blah. It doesn't matter. I just can't have it, due to reality, or other financial desires or commitments. And the owner of Headamp doesn't, and shouldn't care.
So enough business 101, amplifiers are expensive because A.) they can be. or B.) you find it to be a large percentage (quite possibly more than %100) of your budget.
This is a hobby, spend what you can within your limits and enjoy what you have. Just like out in the real world, it's not Ferrari's fault or a Ferrari owner's fault that you don't have a Ferrari. It's yours because you can't or won't spend the money. It makes no sense to feel disgruntled because of that, enjoy what you can or do have and make the most of it
