"Freddy50":
Looks like you got a nice and simple audio system here, and I would not do anything to change that.
But now, I am with "Mrjstark" when it comes to the speaker recommendations for your home theater.
I too, would stick with JM Labs and go for the less expensive Chorus series as they have the best chance of matching up sonically (if not exactly visually) with your Electra 926's.
But now, as for a subwoofer, I am going to ask you to trust your own ears here, and it is you that should determine what sounds good to you. Get the best sounding subwoofer that you can afford and that can blend in sonically with your JM Labs. If pushed in a corner for choices, I would that you would look at subs from HSU, SVS, PSB and Velodyne.
For Receivers??? I would look at models from Denon, Harman/Kardon, Marantz, Onkyo and Yamaha. I would start at the $500.00 offerings from these brands and just go up when certain features and more power begin to look more attractive to you. You should get a nicely equipped receiver for no more than $1,000.00 at the most. But today, even the inexpensive models (and again, we're back at the $500.00 models) offer HDMI connectivity (and in the case of the latest Onkyos, the latest codecs).
And for DVD Players??? I have every reason to believe that the battle between HD-DVD and Blue-Ray may finally be resolved sometime soon. If not this year, certainly within the next two years. So, with that said then, I wouldn't spend a lot of money on a DVD Player at this point in time. If you have an existing but an otherwise good standard DVD Player, I would stick with that one for the time being. On the other hand, if you are in the market for a new player, then I would try something inexpensive like a Toshiba (you should be able to get a decent model dirt cheap) or an Oppo until things settle down on the High Definition DVD front. When a winner finally emerges, I would go ahead and update the DVD Player then. But until then, I wouldn't spend no more than $150.00 to $200.00 on a DVD Player.
As for cables, I would just go ahead and shop around for the best deal at this point. I can't say which cables to get, but what I would say is that I wouldn't spend a lot of money on cables if I were. Home Depot and Radio Shack would be good places to start here. You can go Monster Cable if you desire to do so, but given the wide price ranges in cables, I really don't see where a $125.00+ cable is any better than a cable that costs less than $50.00.
Well, I've given you a somewhat good place to start. At about $2,500.00, that should give you a home theater system that is more than good.
Good Luck and Happy Shopping......
