My position is affected more by all the lousy consumer grade electronics and appliances that have failed long before they should have or failed because the manufacture was counting on planned obsolescense to keep their revenue stream flowing.
I can't even count how many expensive items have died prematurely due to failures in the board that were simply not cost effective to repair.
Our society has been trained to accept failure, to be afraid to buy a new product without an extended warranty, to accept disposable consumer electronics as normal.
I can't avoid buying certain items that are built with offshore labor, like Computers, but I do so reluctantly.
When it comes to buying bass and guitar amps, I do have better options, supporting highly respected custom builders who are absolutely dedicated to excellence.
And yet, again, the reliability of amplifiers (as measured by failure rates and need for repair) continues to exponentially improve. Again, your premise makes little sense to me. That being said, I too have purchased some products just due to their 'handmade' or at least uber quality vibe (Monique, Glockenklang, Walter Wood, Thunderfunk, etc.). Beautiful stuff that sounds great. Are they more reliable, more easy to repair, or do they sound better in an absolute sense than the uber quality, current mass produced units I also own..... to me, not at all.
I will again +1 your point that, if budget allows, as has been the case since the beginning of time, I always recommend staying away from the total bargain basement stuff for sure... products that are made primarily to hit the lowest price point possible.
That being said, my primary point in this thread is that a player who eliminates an entire class of product, regardless of what that 'class' is based on (power amp type, power supply type, preamp design, number of knobs, etc., etc.) might very well miss out on the amp of their dreams. Kind of similar to posts I see saying 'I like the sound out 10" speakers', not realizing that there is just as much variance in tonality and performance within 10" driver loaded cabs as there is across cabs with different driver size. Focusing on the most obvious or vivid difference (e.g., power amp design, size of driver, neck through versus bolt on, etc,) is not really the best way to narrow down options IMO and IME.
The great news is, there are more options out there now than ever, and everyone should (and assuming you have enough money, can....)like what they play, and play what they like
