Amplifier warm up


I was plalying Boz Scaggs, "Silk Degrees" LP.  After side one, I ate dinner.  One hour later I played side 2.  The second side sounded clearer, more vibrant with better sound stage. I have a Parasound P6 preamp and Parasound Halo A21+ amp.  Is it possible that an hour of warm up improved performance?

have not heard of cool down concept for amps

not sure it matters, but pretty sure it doesn't hurt

twoleft is correct - from dr vinny @ wine spectator:

"Petite Sirah (you’ve clearly seen some of the wineries that use the alternative spelling of "Petite Syrah") and Syrah are two different red grapes. Syrah (also known as Shiraz in Australia and South Africa) hails from France’s Rhône Valley, where it’s the primary component of some of the world’s most revered red wines from Hermitage and Côte-Rôtie.

Meanwhile, Petite Sirah is the American name for the Durif grape, another French import, which is a cross between the Syrah and Peloursin grapes. Durif never took off in France, but it did in California.

Even though its name implies it may be a lighter version of Syrah, this is definitely not the case. Petites are anything but Petite. I’ve heard that Petite Sirah got its name because the grape bunch looked like a bunch of Syrah grapes, but with smaller berries. These smaller berries mean there’s a higher skin-to-pulp ratio in the grapes, the resulting wines are inky dark and bold, with rich flavors and powerfully dense tannins. Petites are much more tannic and rustic than Syrahs—I often get wild blackberry and huckleberry pie flavors."

There are a few other possibilities that were not considered:

1. Side One of the LP may be your favorite and thus it may have gotten more play and is showing its age compared to Side 2 that is more pristine.
2. By the time you had finished your meal, the power grid in your area may have become less busy and therefore better suited to your listening session.
3. That bong hit.

4.  That ribeye steak in your tummy makes you sleepy
5.  Those three glasses of petit syrah makes you loopy
6.  That square of tiramisu pushed you over the edge

lololololololololol  ..........


yes ss gear sounds better when warmed up, running a while

i am not sure leaving a power amp on 24-7 is a good idea... stuff does degrade over time with heat... if you are listening every day maybe ok, but if not using for a while, maybe still better to turn off

little more green too... if you care about that
