My dog is very wise but i dont think his relation to some harmonics bundle imitate mine and he certainly does not discern no more than my wife did the difference between tubes and solid state...
But my wife as the dog react favorably to the room controlled acoustic...
I concluded that some dog are better educated in audio than others... 😊😉
Or perhaps my Sansui alpha sound more like tube than S.S. Anyway i owned only 2 tubes amplifiers in the past and the more fluid and meaty sound the more " tubes sound" come with my 2 solid state Sansui...Perhaps it is not the room acoustic my dog spotted but the Sansui alpha ... 😉
We must organize a listening dogs blind test ... Where do you live ? 😁 Perhaps one of us own the next RCA Victor dog ?...
My dogs like my system. I have a love seat with my side in the sweet spot. One of my dogs always jumps up and listens. Likes classical, and jazz… but not the crazy frenetic stuff. In the much earlier days when I had solid state stuff other dogs and partner would leave the room. It is a great test of how natural your system sounds.
