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.

installed new 4s11 canare speaker cables with double wiring to fit my recently acquired PBN speakers. I got about 30 hours on the cables and they have been all over the map so far, specially the first 25 hours. Sometime bass lacking, sometimes piercing highs, sometimes opposite. For real. The last few hours they seem to be stabilizing and I can start seeing their potential but it will take a lot longer to achieve it. So yeah, speaker cables do get better with use, not a single doubt in my mind.
Same issue as when I installed Canare 4S11. I allowed them to break in for 200 hours during which the sonics were  changing all over the place. After I had given them what I thought was enough time, the highs sounded harsh and brittle. I gave up and put them in the closet. 
A few years later after a major system upgrade, I tried them again due to all the good user reviews. After another 200 hours they settled in and presented a smooth top-end, very good dynamics, and a level of transparency that was an additional upgrade to my system.

Cable burn in ? That is another Silly story for those with a wild imagination.

I am really sick of Miller saying that people who don't agree with him can't hear.
What he really means is people who don't agree with him are honest listeners and don't imagine things that don't exist.
He sets himself up as a goldenears when in reality his ears are just the same as ours.
On the evidence it is no doubt impossible for him to stop being so rude and offensive.

I am inclined to go with those who don't consider there is much discernable change during burn-in.  Oldhvy may have it right.

But if OP is concerned, why doesn't he ask his dealer to lend him cables that are already burnt in beyond dispute, say 1000+ hours.  I am sure that will settle the issue for OP and enable him to make a rational choice without worrying whether burn-in is real or not.

By the way I love Siltech cables.  All my interconnects are Siltech.  I have something bigger for the speakers.

600 hours for your ears to adjust to the new equipment?

As often noted, the break-in period is one hour longer than the 'warranty'.
