XLR I/C's for Hegel H20 amp-P20 preamp-VEGA DAC

I hope this is the right forum to ask for anyone who can suggest for balanced interconnects.

I am using two pair of 80 usd a pair of Canare from HAVE INC. of balanced interconnects to connect my system. DAC-Preamp-Amp

It sounds very good, but with some music it gets a bit metallic and noisy and i am trying to achieve the best possible performance from my reference system, so i am considering something that helps the system to become richer, maybe a little warm and take out the annoyances of metallic and harshness.

I read somewhere around here that Hegel sounds best with MIT XLR balanced, the people from Hegel told me they have great results with Nordost Blue Heaven and they claim that HEGEL gear does not need expensive cables BUT they should always be balanced to sound its best.

Other brands that are intriguing for me and represent certain Value:

WyWires Blue
Nordost Blue Heaven LS XLR
Audio Art Se XLR
Dynamique Audio SHADOW

Please any suggestions, specially if anyone owns Hegel gear, would be so much of help!

Best Regards to all
