Hi
I have an LM 3886 amp that comes with speaker disconnect switch
is it better to put in in a timer circuit instead of using the switch
If I forget to trip the speaker switch on shut down, I risk damaging my speakers
does the timer circuit i'm thinking of degrade the sonics in any way

Yes, having a switch on delay and a rapid disconnect is always a good feature. There are many designs around of varying complexity. Here is a simple one I designed that would fit the bill,

I would rather have the choice between a damaged speaker, or perfect sound quality.
Once that choice is available, I would choose the "NO DAMAGE" option.
Is your thinking along the same lines?
Or, are you prepared to accept the risk of damage in the search for that "perfect sound"?

If you forget to trip the speaker switch, why would your speakers be damaged on shut down?If I forget to trip the speaker switch on shut down, I risk damaging my speakers
Big DC or AC pulse as the amplifier drains the supply rails.
Some amplifiers become unstable and oscillate badly during this shutdown. This can burn out Treble drivers.
Delayed ON ans instant OFF is very useful. Even when the tiny bit of added distortion is included in the overall protection system.

....................This is a LM3886..............

is it just a 3886?................The amp also has a tubed pre it's an integrated with phono stage
It's an integrated amp that has 12b4a tube pre and lm 3886 chipis it just a 3886?
with a separate power supply
