Problem with Arcam or JM LABS


I have an Arcam AVR 250 with an Arcam DV78. The speakers are JM Lab 716S Chorus Line(mains) w/ a JM Lab 700S Chorus Line (center) and JM Lab 716S (rears). The front 3 spkrs have Rega cables. The problem is understanding the dialogue from the center channel when watching movies. We think we have everything hooked up correctly and every setting set proberly. We have adjusted and readjusted every setting many times with little or no improvement. I have been running the mains on 0-5 with the center at 6 and the rears around 2-4. I purchased a sound level meter and set the levels correctly. No help. The voices coming from the center sound thick at times and slurred. We have tried the center at 5' and 2' with no improvement. The odd part is that I can understand every word coming from my TV during a broadcast when it is coming out of the center. Is there anything I can do to brighten the sound or is it just the British sound that I will have to learn to deal with. Thank you for your time.

My wife and I are also just north of 50 and she has a slight drop in hearing as well. as I said in my earlier post we were using JMLab 707S and 700 center. We just changed our speakers. We went with Paradigm S8 fronts and a C3 center - and the center has made all the difference in the world - dialogue is now improved drastically. The C3 is larger than the JMLab 700 and is also a 3way design. I would think about upgrading the center channel based on our experience.
I am now considering ugrading my center to a JM Lab Cobalt or Electra line from my original Chorus CC700. Is there anyone out there who can honestly say that this upgrade will really make a difference. Thanks to all.
No, don’t upgrade the center channel just yet. Try a new speaker cable first. Also, if you are using cheap interconnects. Try upgrading here as well. Do some more experimenting before you come to the new center channel conclusion.

I have good luck with Wireworld Starlight Digital Cable. Call The Cable Company http://www.thecableco.com/ and ask them for a demo. Also, Wireworld has a full compliment of cables for your entire system. They are very clear sounding.
I had the same problem with my centre channel (Wharfedale Diamond with Cambridge receiver).

Some of my problem was because I had the cc placed vertical, instead of horizontal (recommended way) but I needed to save some space. and I had to angle the cc slightly upward, as it was at about knee level when sitting down.

But, the biggest help was adding this device called a BBB Sonic Maximizer, its cheap and well worth it.

Before I did that I wasted a bunch of money on MIT cables, B&K amp,cardis cables.

Oh well, live and learn
