In the past I was a bit of a hi-fi buff, and I built my own amplifiers and active crossovers and put together my own active speaker systems. And I got what I think were fantastic sounds at very modest prices. But the high-end hi-fi world was awash with pseudo-religious tripe, with high-profile reviewers insisting they could hear minute differences when using even different mains leads (I kid you not) - "the third player in the second violins sounds a bit off-key with this lead", honestly, crap of those proportions
Why did you bother building your own kit when everyone knows that all amplifiers sound the same?
