Way off topic but I’ll indulge you this time. What you say would be true 30 years ago but no longer is.
That's why there is like dozens of high-end companies out there still making tube gear for the best of the very best? What you say is probably true in the consumer market. I don't run consumer gear. I only use professional gear and stuff I personally designed, modified or built myself and believe me, for $2000, I can build that $15,000 amp you'll never hear. Then multiply that by 5 speakers per channel in three cabinets per channel run by 6 power amps putting out 3,000 watts and a whole lot other.
Others reading this will be wondering what on earth this has to do with God or Gods but let’s not tell them, they’ll really think we're mad if we do.
But it DOES have everything to do with God. Believe me, I see him every time I turn on my system (turning it on involves 17 steps). We dance together.
By the way, what’s ‘VB’ audio?
Voice Band. Not an entirely appropriate term borrowed from the telecom industry in the context I used it in, but considering my system goes down flat to about 10-12 cycles (definitely below 15), an octave below audibility, I thought it useful enough.
Most consumer gear that claims 20 or 30 cycles +/- 3 dB is really down like 10-15 dB when I measure it. Hard to imagine having bass that really IS flat more or less (within 2-3 dB) from 100 cycles all the way down to nearly DC. It hits you in your chest and stops your heart. BTW, my system has 45 amp service to draw from on a 60 amp feed. I know you understand what that means.
