upgrade advice


Hi
i bought the Hegel h160 integrated amplifier with pair of Spendor D7 loudspeakers.
the source is bluesound node 2 .
speakers cables are VOVOX vocalis. all other cables are regular.
i want to upgrade my sound and wonder what would be the best way to start.
to change my power cable,my digital cable,speakers cable or buy a better external DAC  than the hegel internal.
thaks for your advice

It sounds like a reasonable upgrade path is use the Node 2 as a wireless streaming transport and feed a better DAC using its optical/coax outputs. I suppose the same DAC could be used to upgrade a CD player sound as well. Makes it a little easier to justify the cost for a good unit.
a lot of this is simply personal preference, as long as the DAC receives a high quality, low jitter signal...
I have a Bluesound Vault and the internal DAC is a piece of crap. However, connected to my Schitt Gungnir Multibit DAC it sounds wonderful.
Yansad, if you haven't already done so and your domicile is conducive then spend money treating your room.
