I have the knowledge and skill to produce a decent DIY version using the Tone Board. What I do not have is the time nor really the interest. And a lot of audiophiles do not have any of the above. Knowing how things work in the business world and what things cost, I don't have a problem with March Audio charging to put it into a decent case and package it as a commercial product I can buy to plug and play. The performance is good, unlike many Schiit products, and the price is in line with a lot of other similar products (higher than some, less than others). I don't care if it is a $1 or $1000 DAC in that $400 box. To me this forum is about the technical aspects and those are good. Maybe my perspective is warped because many real-world products leverage prior art and utilize the same or slightly modified versions of the same basic parts to produce competent, reliable products with reduced development cost. Reuse and all that jazz.
My surprise is with the amount of vitriol about using a known-good board to produce a product vs. rolling your own arguably worse boards to use in essentially the same product. If it was $10k it'd be in the "insanely outrageous expensive audiophoolery" thread but at $400? If the price is too high, just don't buy it. Let the marketplace decide. This seems too much like "shooting the messenger" when we get the inside track on a commercial product development and then scream bloody murder at the result. Way to drive away a good contributor. Heck, he could have just not provided a test sample and avoided all this.
I personally tend to not post negatives, not because I do not have strong opinions about some products, but because I was raised in a "if you can't say anything nice, don't say anything" household. If it's not worth the price, it will cease to exist as a product.
Now about those amps...
