I came in to the hobby in the late 2000s and was heavily invested in boutique brands. They seemed to offer more performance for the same or less money.
While this may or may not be true subjectively, boutique brands come with what I now consider unacceptable risks IMO.
1.) They usually are small operations that are one incident away from ruin. When this occurs support for the product disappears and anyone that had money invested towards a product is usually out of luck. Many online occurrences of deposits or payment lost when a small company goes under.
2.) Because boutique brands are smaller in size their purchasing power, man power capabilities, and output can become significantly limited quickly. Again, if you look around there are a lot of instances of product taking many months or years to ship. Right now is crazy for everyone because of the pandemic and the supply chain. I doubt in 2017 many people were waiting 12-24 months for common speakers from Magico or Wilson. Nor do I think that any one person at either of those companies would bring shipments grinding to an extended halt.
3.) Resale value is, IME, much worse for boutique brands, especially if the company has gone under.
That being said I had a great experience with Salk when I ordered a pair of speakers back in 2015.
