Certainly there's a positive correlation between size/weight and cost. Wealthy audiophiles exhibit inelastic demand.
Not sure what you mean by inelastic demand. Most say that weight is unimportant but I always look at weight as you do. Certainly there is no direct correlation but I think it does represent the manufacturer's effort to engineer quality into the gear and what the manufacturer believes to be important.
I personally don't care for DAC's that separate every part of the D/A conversion into a separate component or monster three component preamps weighing over 100 pounds. I don't maintain that a Varese is
not better than a MCD12000. It absolutely is, no question, but is it worth five large boxes? And if you go this route, something like it is where you wind up. The tube outputs of the MCD12000 impart a wonderful coloration that the 276K Varese cannot impart. It's way over the top for me, even if I had the money. I'm using it as an example as I am the MCD12000. The Wadax Studio Player is on the cover of TAS. I haven't read the review yet but I am sure it is quite positive and I have no doubt, if I had a system other than McIntosh, it would be first on my list of DACs.
However, the resulting sound quality and dynamic range necessitating the complexity and weight of a Chronosonic XVX cannot duplicated by a wooden 150 pound box that is not time aligned. It's choosing the size, complexity, cost, and weight commensurate to your taste and recognizing that these parameters cannot be dismissed and one must choose carefully. Obviously, no one has the heaviest, most complex, costliest, and largest gear available.
My backup 7 year old MC1.25 KW will be returning from Nashville Amplifier Service Friday. I had the meter replaced. McIntosh furnished the 1000.00 meter at no cost but the repair still cost 515 dollars. I paid 140 dollars for priority service. If this had been my new MC2.1KW An it probably would have to return to McIntosh and the thought of removing this 3 box monster amp from my system is something I don't want to think about.
This company is truly excellent at amplifier repair. They checked out the whole amp and had recently repaired a MC462 with a blown output transistor due to a loose heat sink clip. This has made me realize that tubes may be simpler than solid state amps after all. I won't be buying the new MC2.1KW for my XVX. I must have it for my Thor, though. I'll take my MC3500's and replace the tubes at my house as needed. It's a simple animal compared to a MC2.1KW.
