I should start off by saying that I’m a total newbie to the do-it-yourself electronics scene. I’m interested in this stuff but truth be told I build headphone amps because I want to use them. I doubt I’ll ever become one of those guys who has fifteen different amps of varying designs and application—but you never know what could happen. I’ve definitely been bitten with the obsession of building the best sounding amp possible for the application and money. I can see that it’s a slippery slope.
