New cables - To judge now or after burn in period?


I am in the midst of auditioning a host of Siltech speaker cables (Siltech Legend 380i & 680i) and interconnects (XLR and RCA - Siltech Legend 380i). Needless to say, they are quite a bit more costly than my existing QED cables (QED Genesis Silver Spiral Bi-wire & QED Signature 40 interconnects).

The Siltech cables are highly recommended by my distributor and seem to be well received by the audiophile press. However, doubts arise as upon trying them at home they do not sound as dynamic as my existing QED cables. While the highs are more resolving and I am hearing things that I have not heard before, the bass seems constricted and the music does not make my feet tap anymore.

Is that because the cables are brand new and have not been burnt in as yet? Or is it because there is no synergy between the cables and my particular system? Or is it a bit of both? If it is a burn in issue, how many hours of burn in is required before I should make a judgment as to whether I prefer the sound of the interconnects and speaker cables?

All inputs or observations are welcome.

Dcpillai, I got this info directly from the Siltech web site:

"Silver boasts the best conductivity of any metal, and this actually improves over time. The new G9 wire alloys silver and gold together to fill in the micro-cracks of the crystal structure, as well as offering improved cable run-in. Far less time is now needed for the conductors and insulators to achieve their optimum performance – under 100 hours is now required, depending on the connectors."

Good luck.
I am not impressed when companies with deep pockets make what are, imo, unsupported claims claims such as a cable relaxing.

The Iconoclast Cables, OTOH,  were modeled and measured, and sold on rigorous testing.  They have been superb in all systems from the first moment. They have bested many other brands that claim break in is required.  

The longer I am in this hobby (40+ years now) the less system building nonsense I tolerate.

Cable burn in ?? Has to be the stupid of stupid. NO such thing period !! Get a life, go to school do something. Must admit my R8 10+ ran so much better when all the wires burned in not to mention the sound system improvement…. Apparently it’s in the fine print of any electronic device sold out there, Don’t make me laugh 😂
