Connecting VC23 and T1 Schematic

Connecting VC23 and T1 Schematic

I tried it both ways, wired to one DPST switch which gives a pop at power off only. If I use two separate SPST switches, there is the pop at power off unless I delay turning the amp off until I see the LED on the back of the Meanwell 350W 27V SMPS go out - bleeding off the caps? Can this be corrected in some way so I can just use the single DPST switch?

And is there pop noise when power on or/and off?
Hi, I saw 2 switches (SW1 and SW2), are they turned on/off together?
Trying to turn the VC23 preamp, SMPS, and T1 amp all on and off with one switch and not have the speaker pop when shutting down. I have a Meanwell SMPS 27V 350W. I changed to a DPDT switch and even though power is cut to the SMPS it still takes a while to drain the caps and I get a speaker pop. Relay with delay or ?

See attached - do you have any suggestions on improvement?

Thanks in advance.
