Was told by my Pass dealer that the X250.5 from standby takes 5 minutes to stabilize and one hour to sound it's best, longer if fully shut off. My Portal Panache recommends leaving on 24/7 and has no standby option.
Again, your car will run better if you leave it running all the time...it will. Hot water...leave the water running and it's always hot AND fresher...sleep with your daytime clothes on...leave the refrigerator door open to cool the house and make food access easier...put your underwear on the floor and cover it with rug cleaner and vacuum it...wear a feedbag while riding your bicycle...pork cousins...inhale asbestos for future medical freebies...only wear socks once like Jerry Lewis...
My gear sounds distinctly better after I have warmed up....usually it's a decent single malt if I am not broke OTW good ole rum is fine. I am told though I can't vouch for this that a wee drop of spirit in the tube sockets does wonders... NJoy
I have a noticeable improvement after 1/2 an hour. Incremental after that, but it does continue to improve for another 1/2 an hour, and that is with my integrated. I leave my CDP on 24/7 as it's draw is negligible so I don't worry about waste and cost.
