So I get the question all the time “Why tubes?”. I usually answer something along the lines of “I just like them” but that really doesn’t sum it up that well. So I have been thinking about that very question; “Why tubes?”. After much contemplation, I think I have come up with one simple answer that sums up my feelings on the topic quite succinctly:

Why tubes?

Because vacuum tubes are like MOSFETs, but with class!

So whenever you go out to an audio equipment forum on the web, inevitability the topic of discussion will turn to resistors. This is especially true on vacuum tube audio forums. And the discussion always seems to come down to two entrenched camps; the Carbon Composition guys and the Metal Film guys. The Carbon Composition guys always claim that metal film resistors make equipment sound “sterile”, “dry”, or “cold”. The Metal Film guys counter with the fact that carbon composition resistors are noisy producing “hiss”, “pops”, “ticks”, or just “white noise”. And then the fight is on. Continue reading →

There is just something about it. The glow of the filaments, the warmth of the glass, and the full rich sound. It’s about the simple purity of circuits allowed to operate as designed without the strictures and totalitarian controls of overly tight control loops and massive feedback.

It’s about something that has been lost in modern electronics. Lost in the sterile specifications, the compromises of cost, return on investment, producibility, and marketing. Lost in the squared off metal boxes, the stark lights of LEDs, and the obsession with numbers having nothing to do with the way it sounds.

And it’s about rediscovery. Finding once again the sound that we didn’t even know we had lost, until finally, by chance, we heard it once again.
