That is a great price on the 3118 with volume control as a bonus, I think folks in 3116 thread would also be interested.

that's bad!
i can chose free shipping at first.
later in the process it becomes something like 23$ shipping.

is the tpa3118 superior to the 3116 with 8ohm-speakers?

I think the main difference is that 3116 has higher output power than 3118. Some of the guys on the 3116 thread like 3118 too. The shop that build this also has a 3116 on sale - that 3116 looks well built too.

It actually sounds quite good. It was after listening to the 3123 that I decided to get the 3116. My personal opinion, apart from higher power, I think the 3116 is a little better in the mid and the low frequencies. Human voice is fuller and the base is tighter. But then I am comparing two different boards with different components, not just the chips.

yes, but datasheet says something like

3116: 50W into 4Ohm
3118: 30W into 8Ohm

that's why i thought i could get more out of tpa3118 for my 8-ohmers.

Both have the same potential output power when playing music. The TPA3118 might get a tad bit warmer if pressed beyond 21V supply voltage and below 4 ohm load but nothing that would be substantial, and certainly nowhere near the thermal limits.
