Dear audiophiles,

My current gear is: Dragonfly Black DAC, Technics su-v620m2 Integrated amp, Mission M71 floor standing loudspeakers.

I would like to know what matters the most to improve my set-up. I am thinking of building a complete new system, made of:

- Bluesound Node 2i as pure streamer
- NAD M51 DAC (found a good price, second hand) knowing that it can't play the MQA at 192khz
- Akitika GT-102 Power Amplifier kit
- KEF LS50 passive

Since I am only listening music through streaming services, does it make sense to invest into a standalone excellent DAC if I pair it with a Bluesound Node 2i to stream that has a built-in DAC?

Should I also buy a preamp or could I plug directly the DAC in the Akitika GT-102?

I have the money to buy all these things, but I'd like to know if that makes sense.

Thanks.
