There is a big difference between tubes and solid state. I own some solid state equipment that takes 3 days to sound its best. However, my tube equipment is stablized after a couple of hours.
How long daes it take your gear to warm up?
Assuming that one turns off/on the audio equipment every day. How long does it take for your gear to perform as it best after a cold start? I ask because my Rotels RA-1090 need about 2 hr to really shine, otherwise the highs are ear piercing and the bass notes lack some punch. Any of you have to go through a similar time of warm up period?
