Cable upgrade

I had tried to up the level of the center speaker but found that these cables made the biggest difference.
The sound for movies is so opened I can understand everything that is going on.

You could also adjust the level of your center up if
you havn't tried this already.

I just tried some nordost Valhalla cables for front three speakers and it made a huge difference to the sound.
The clear opened sound that I was looking for these cables gave me.

Center speaker is only 2 months old and has been rated to be quite a good center speaker.
I am using the Bryston bbs2 for my contour 5.4 fronts and am using the Arcam avr 600 to drive my rears and center.
I'm not to sure where I'm going wrong?
If it's the Arcams preamplifier section then what would you recommend?
I have tried different cables such as Tara labs vector 2 and chord signature and did hear a difference but these were only minor differences.

Your dialog issue is either your center speaker or your preamp

Keep spending 250-2000 $ on cables and interconnects. I did but sold them all. ANTICABLE results, not hype.

I think for me I'm looking for a more open sound when watching movies.
When I have action and dialogue in a movie sometimes I find it hard to hear what the actors are saying.
I'm not sure if it's just my room or cables that I'm using for the 3 fronts?
I use Audioquest Cv4.2.
The room is 5 meters x 4 meters have a large rug in the middle of it.
Big wooden coffee table in the middle.
Timber blinds on one side of the room and half opened on the other side which gose into the dinning room.
Also have a large L shaped couch.
What do you think my dialogue issue is?

For bryston gear, I always liked Brystons cables the best. There are cables out there that have much fancey jackets, but Ive found the Brystons have the qualities I'm looking for in a cable, and there very affordable compared to many that I felt performed less.

Ive been in hi end audio, and studio recording for many years now. Its Bryston all around for me personally.

Thanks for your feedback
Just wondering why you changed over from your dynaudios to Tannoy?
Did you find the Synergistic cables warm sounding with no loss of details?
Thanks

I had excellent results using Synergistic Research Resolution Reference FX with my Contour 5.4's. I am still using these great cables with my current Tannoy speakers. These cables are not made any more, they are an older, discontinued model. You may find some used, or a current SR model, I'm sure will work fine for you.
