Since I'm doing research myself, I'm going to list some boards here I find interesting.
*Disclaimer: These boards are only interesting if the information I read was "correct". Meaning, I read Intel LAN and Realtek audio is more compatible. The other factor is that 8 phases are better than 4 phases. It may be debatable whether this is necessary for people who don't overclock but in any case, if you look for these three parameters, Intel LAN, Realtek audio and 8 phases, here are some boards...
(Also, I said compatible. I didn't say Realtek was always the best. I did not include Realtek ALC887 because I didn't see if it was compatible with Blu-ray audio. I also did not include WS models because they're workstation models probably more compatible with Xeon processors.)
Asus GRYPHON Z87
LAN: Intel® I217V
Audio: Realtek® ALC892 ($185, Blu-ray audio,
micro ATX, TUF components, four USB 2.0 on rear panel, complete rear audio panel)
phases: 8
Asus Z87-PRO

phases: 8
Asus MAXIMUS VI EXTREME

The (regular size ATX form factor)
Asus Z87-PLUS is interesting and even the (smaller) micro ATX
Asus GRYPHON Z87 are less expensive than the other models listed here. The one thing I find confusing though is when they put "Digi VRM" in their descriptions. Is that a hybrid or analog VRM? One person on another site said some Asrocks were not really digital, but analog. So writing "Digi" instead of "digital" makes it look a little suspicious. But, whatever. You can only find the information you can find.

A cheap model I found was the
Gigabyte GA-H87-D3H which has Intel LAN and Realtek audio.

I did not make a complete search of all Gigabyte and MSI models because I didn't like the fact I didn't see the number of phases listed on their site. So, I hope someone appreciates the research I did on this even though I'm not an expert.
EDIT: I looked at a lot of current motherboards including Gigabyte and MSI and the ones I highlighted in blue are more interesting to me.
