The amplitude starts dropping at 2-5kHz and at 2+kHz it is approx 3 dB down.
The fase will normally start turning at 1/10 of the amplitude-drop. My guess is, that the fase of this amp starts making funny things around 500Hz.
Ok, here is my baby - i realise it's not like i built the board from scratch, but still, as someone who never soldered a single wire or crimped a single connector before this project, I am pretty proud of my work 
It's a v1 version, ventilation obviously sucks, will be addressed by more holes top and bottom, and I'll add automatic input selector a bit later. With 24V power supply it's goes pretty loud ;-)

Congratulation ! Well done for a very first project )
bithloman, you may want to post your question in a separate and new thread as it is a very wide sweeping question.

An externally hosted image should be here but it was not working when we last tested it.
This is my first audio project, a stereo combo amplifier built using a TPA3116D2 board.
It has a bluetooth module with USB & SD card input, FM tuner, and 1/8" & 1/4" L+R Phono inputs. The amp has an EQ with Bass/Mid/Treble & Volume, and there's a speaker protection/delay board to get rid of power-on thump. It's powered by a 24V supply, with a stepdown converter to run the bluetooth module. The box is an open-back slant design built around 6 ohm speakers salvaged from an old Sony shelf system.
I'm really enjoying the flexibility of this little thing - it's a stereo guitar practice amp, a boombox, a radio, a media player, and bluetooth party speaker all in one.
Yup love wago connectors makes thing so much easier and neater
It sounds much better than i was expecting very suprised at how cool it runs the modushop case is overkill if i am honest.
I am am strongly considering building a 11ch one for my home theater setup
