I started in my teen years. Being middle class folks, my first taste of good audio was a hand built HH SCOTT tube amp, then a Dynakit.ST-xx(i forgot and all this are surplus gear). This was all driven because my college degree was EE and Amp projects is where my interest was.
some of my family friends owned Pioneers, Sansui and Marantz. they all sounded so good, that my homebuilt HH Scott was no match.
Since i have very limited budgets, i modified the HH SCOTT changing caps, re-bias and even doing my own transformers. finally i got it to sound as good as the modern Marantz..
Growing older and in my working life, i settled with DECWARE gear (amps and Pre) with LOWTER Acousta for the longest time.. and now, all these are gone and i have settled for Pass Labs, Falcon and ATC / REL
