Do I need a center channel?

I'm like you, Michaelingdom, and all I have is a 2 channel set up and it works just fine.

If you sit in the middle, no.

Don't think you would gain anything and depending on your amplification and center channel speaker, you could end up taking a step back.

I also play more stereo than 5.1. But the centre was more important than I thought. It is in 5.1 the most used channel. Wenn you have a matched centre the integration and natural sound is a lot better than without. I use a Monitor Audio Platinum centre. Monitor Audio is a brand which make one of the best crossovers. The advantage is that it can build the stage also far behind the centre like the best highend speakers can. With this extra depth you get stunning results in a much more 3-dimensional sound. Most people use brands with poor or average crossovers. You get often a very direct and what I call 2-dimensional sound.

No.

Forget it.

I use 2 channel HT and to be blunt think the rear channels are simply gimmicky. A good stereo setup images more than well enough to make the center channel redundant. It saves you money overall and by getting better 2ch components sounds better to me as well. For example listening to HT I use a NAD M51 DAC and have yet to find any HT processor/receiver to touch it sound quality wise. And I have other DAC's without the connectivity of the NAD that is better again.

I checked out a supposedly good HT receiver, an Anthem, and to be blunt its SQ was ordinary, very ordinary indeed. High quality 2ch is the way to go.

Thanks
