    i have a pioneer vsx-510 and want to know should i have the amp on all the time or should i use the stand-by button ,i say this because i`ve heard that some amp`s take some time to warm up and that`s when u get the best sound rather from a cold start or i`m i talking b.s

    It's true that most amp's "work best" once they've warmed up, but to be honest, it's entirely up to you. I'm fairly mindful of my electricity bill so tend to leave mine in standby, but others on here leave there's switched on 24/7.

    You could always just make a mental note to switch it on a couple of hours before you sit down to watch a film if you want the best of both worlds :)

    I don't have a standby on my Yammy receiver. I turn it off whenever I'm not using it, but it's always plugged into the mains socket.

    Not all amps take time to warm up, its the amps containing large capacity caps in the power supply that have the most trouble. Components like Black caps take an age to fully charge due to the dielectric constituents, these need leaving on for a minimum of 24hrs.

    Naim amps are particularly vunerable to this, the advice is clearly indicated in the operating manual. If you listen to a dealer dem of a just switched on Naim, you will wish you had'nt, the sound is harsh and lacks bass, 24hrs later its a different beast.

    This doesnt apply to more budget amplification and I would include the majority of HC amps in this league.

    karkus has a good point here,and I always leave the low power consumption items in my system(processor/dvd/cd/upsampler) either in standby or permanently on,but the amps are left off until required due to cost considerations!
    As he says,most AV amps won't need a lengthy warm-up,but high powered Class A amps certainly do,and Krells/Levinsons etc dont give their best for at least 30-60mins after a cold start.
