Advice on new cables

I have 1 dealer by me that uses all MIT or Transparent cables. Personally the tonal quality is excellent but to me they lack dynamics. Now it could be the networks were not matched to the equipment and if that's the case that's the dealers fault. For that reason I did not care for them at any price. I like the Nordost cables personally but not everyone does. I think the folks that have entry level equipment will say they are thin sounding and bright. Not for me though. Regarding Nordost they just announced at the CES they have a Series 2 in the Norse series. I'm currently running all Frey's and when my local dealer gets his Series 2 demo case I'm willing to demo them and upgrade if they are good as they say. I've heard the series 2 Tyr is better sounding than the Valhalla's. If that's the case I will own a pair.

I highly suggest the cable company to try
That way you would know how they sound in your home on your system.

Thanks. I am exactly looking for more dynamics and rhythm without loosing warmth.

My current MIT cables are the following: Shotgun AC1 power cables; Shotgun S3 balanced interconnects; and Shotgun S3 speaker cables.

Why would you think that your cables are limitation?? I think your speakers and amp are suspicious.
