Hi from Tauranga, looking to introduce myself, and collect your views on upgrades to Quad 405.

I seem to be on a bit of a resto-mod crusade. My other hobby is my 1967 MGB GT, about to have a full suspension upgrade, to allow me to better enjoy the extra horse power from the installed Toyota 4-AGE 20 valve motor and 5 speed gear box 😎

So I am giving consideration to either:
- Net-audio MK3 boards wth Op amp upgrade, or
- Dada Electronics Quad 405 Upgrade-kit with OPA604 v3 High-end boards

Anyone been lucky enough to hear both? What are the merits of the 2 options. All advice greatly received.

The amp will be fronted by my SoTM sDP1000 pre/dac, driving Thiel CS1.6
