Absolutely. Sight, hearing and the brain are inseparable elements of sound perception. If one accepts that, then one will more readily accept that the showroom would be a place where one could accurately judge sound quality. But then there is the acoustic of the showroom that may be better or worse than your own room. So how is it possible to rule out the acoustic of the showroom?
Okay, never mind. The truth is not important.
It's all about enjoyment, and the upgrade bug! Now apparently, recording studios don't care about sound quality and that's why they use solid state gears in most cases. But you and I can buy tube gears to bring back the tube sound even if the recording was done using solid state gears. Just a thought.
How convoluted is the audio world! We are all humans and believe in what we hear from our fellow human beings and we all agree that tube is best, and that it has nothing to do with marketing, or technology. Perception is everything so they tell us it's the number one rule in Customer Service.
