McCormack dna1 to Sony 1040

If your receiver is a Sony STR-DN1040, which WITHOUT pre-out jack, you can't directly connect it to a McCormack DNA-1 power amp!

Yes, tis49's suggestion will work, connect the Sony receiver front speakers outputs to a Speaker-level to Line-level Adapter then go to the DNA1 inputs.

The DNA1 can provide much better power to the speakers than the Sony! Same concept of Musical Fidelity 550k/750k supercharger.

@edsnipered,
You posted your question in home-theater section, what is your goal?
You want a two channel set-up or a multi-channel home theater system?

For your budget, go passive, the DNA1 has high enough gain and input impedance for a passive preamp, check out the Schiit

Pair the Bose with the Sony, not saying the 10.2 is not good, but your DNA1 deserve the best!

How bout klipse rf62

Ideal speakers for parties!

edsnipered,
If you want to focused on two-channel audiophile quality sound and want some floorstanding speakers to pair with your DNA1, my suggestion is Thiel 1.2/1.5/1.6 or even the 1.7, you also can search the system page to see what other members choice of speakers for the DNA1 or ask a question on speakers section in this forum for recommendation.
