Default MOSFET amp - thump at switch on.

I have a denon here with a little relay like this, the problem seems to be
that relays get dirty, or wear aas this one has and e distortion varies and
the levels wobble when its time to take the lid off and do another contact
cleaning job...

Common way to stop the thump you can tend to get with a MOSFET amp at
switch on was a relay on the speaker output.

It occurred to me that in these days of cheap high power triacs it might
be better to ramp up the AC into the amp - even if it uses a conventional
power supply?

Comments welcome. ;-)
