Bluesound NODE 2 paired with Benchmark DAC 1?

I use the Bluesound Node with an Ayre Codex.
Sound Great to me.
I think the Benchmark would be just as good.
Who makes a 300b amp, and are you using a preamp?

Thanks Bob,
Softone 6w, with no pre

I have the Benchmark USB DAC1 with the Bluesound Node 2. The pair sound very good, but surprisingly not that much better than the internal Bluesound Node 2 dac. When I switch to about 8 out of 10 MQA albums, the Node 2 sounds the best by itself.
