Hdmi (I2s) upgrade

I have a Pangea Premier SE HDMI cable that I use between my transport (Jays cdt2 mk.II) and my DAC ( Holo Audio Spring 2 KTE Edition). Although the cable sounds very good, what other HDMI cable under $500 would give me a noticeable improvement. I was considering the Audioquest Diamond HDMI cable.
thanks
