Build Your Own Professional-Grade Audio Amp on the Sort-Of Cheap
Audiophilia is a study in contradiction. The ask is a flat &quot;uncolored&quot; accurate sound. The gear that sells for ridiculous prices is usually tube gear with limited bandwidth and makes ~15 watts at 5-10% (admittedly usually even order harmonic) thd. Hardly uncolored.<p>That said, and Ive mentioned this before on HN. My (now late) uncle had a bunch of audiophile friends in Dallas. He hung around folks who had spent upwards of 500,000 (yes you read that right) on audio gear. I can&#x27;t forget the time I rolled up to a modest middle class home, only to find out that inside of this house was a pair of Focal Grand Utopias (selling retail for 250k at the time, though he said he paid around 60k for the pair). He had 2 750 watt tube amps, current era but the brand escapes me. For source material he had a heavily modified Technics SP-10 with 2 tone arm&#x2F;cartridge combinations and a boutique tube phono preamp. This fed into a similarly heavily modified Dynaco tube preamp from the 1960s. When he really wanted to get serious, though, he had a studer 2&quot; tape machine and a sizable collection of low generation master tape copies. If I hadn&#x27;t seen this with my own eyes I would say my uncle was full of shit when he told me about it. You know what? it sounded freaking amazing.Im sure it is 90% placebo, and 10% the fact that he was able to play high bandwidth audio to concert levels with no stress or strain from the amplifiers. Was it worth 6 figures of money? not to me. But I am glad I got to hear it...
