12 years or 18 years?

Your experiences please..
When I listen to my state of the art 2.1  Bose tube amp system, I drink a 12 year old single malt whiskey. The sound is warm and smooth. When I switch to an 18 year old single malt, the sound is smokey and woody.
Your thoughts and recommendations on a warm  and  smooth 18 year old single malt whiskey.
TIA for entertaining my question. Stay Healthy and long live HiFi!
