I think SMD parts is better for signal, but I use hole-through parts for analog at last, will be easier for DIYer to improve. I think it will not be expensive for most people.

It's good to use the chip you metioned for multi_channel, at least it's cheaper. But it's possible to use this board for 8-channel using.

My very first soldering experience (other than cables) had a surface mount chip. I later soldered many amp32 from 41hz and it is actually easier and much faster than through hole once you get the hang of it. Everything nice going SMD it is hard finding the best parts through hole I have heard?

Don't you need 4 pcs 2310 for 8 channels including higher component count on the board? Total cost might be similar.

Also, Hifimediy delivers ready made kits and is also using many SMDs (diodes, TK2050, caps, resistors etc) so for him I would suspect it would be easier to do SMD than throughhole.

But at higher cost and larger footprint ...

Oh well... I'll wait till you make a 8 channel volume control then

It won't make the slightest bit of difference.

I'm doing 24 channels at the moment. Doesn't take a lot of space.

Lets just say that it is a relative term.

Add some functions( use switchs on board):
sw1: on-auto save configuration when power off; off-default configuration
sw2: on-display always on; off-display blank after about 5sec no action
sw3: on-remote learning mode; off-normal mode
sw4: on-ZCEN enable; off-ZCEN disable.
