Best way to go HT with focus on 2 channel

A home theater processor would normally take the place of your pre. Usually the home theater pre/pro controls your volume, processes the dolby or dts signal on the dvd and cable/sat box and handles base management - crossover points (also speaker distance and time alignment). All good ones have an analog pass through.

There are some ht pre that don't do any processing, they just let your dvd (or universal player) do the signal processing etc. Mccormack MAP-1 is one that I can think of off hand. There are several more. I don't know what would be gained (other than the tube sound) by keeping your current pre in the chain.

You'll see a lot of advice on this forum saying you don't need a center channel speaker or subwoofer, but to get the real home theater experience I think they are critical. In this months stereophile mag the surround column makes one of the best arguments for a center I've heard. If you like action movies you'll miss a ton without a sub.

No knowing what speakers or amp you are currently using makes its hard to recommend much more.

I've tried HT for music and sold them off after couple month. It is night and day difference. Not good for serious listening.
Even playing the DVD msic video, the 2 channel sounds better. The HT mode gives you background noise make you feel like you are sitting in the middle of room. The 2 channel mode gives you front row experience but with much musical presentation via 2 channel preamp and amp.

For a medium to small room, I would probably hook up HT with computer and computer speakers to get the same HT effect. Get a HDTV card for the PC will do just fine.

The best way is what Fedreams sugested.

Smccull,

First, I have been going through the same scenario over the last 5 years and have had many different iterations of "combo" systems in my listening room. I speak from years of personal experience!

There are several different ways to go about adding HT to your system. It is all going to depend on your budget, how much hassle you can tolerate when engaging the HT portion of the system and how much sonic performance you demand from the HT portion of the system. I do like the fact that you seem to want to add-on HT and not try to mess with your existing 2-channel rig that you currently enjoy.

I did not see what main speakers you use when I viewed your "system". For quality HT, you will need (at least) to match the center channel speaker to the main L&R front speakers that you plan to use in the system. If you don't plan to do this, or if there is not a matching center channel speaker to your mains, you might want to consider not even bothering. Maybe just add a sub to your system and crank it up a bit when watching action flicks. Of course, you can always use "phantom" center channel mode (no center speaker, center content sent equally to L&R fronts).

If you truely like your current 2-channel system and want to add HT, the easiest and least expensive way is to buy a decent HT reciever with (at least) L&R main pre-outs. You can connect these pre-outs from the HT receiver to a processor loop/HT bypass on your pre-amp, or, if your pre-amp does not have a bypass, simply connect the L&R pre-outs to an unused input on you pre-amp. Now, you current 2-channel rig (amplification and speakers) will provide the L&R front output for the HT system. Connect center, surrounds, sub and HT source devices to the HT receiver.

As you can see, this setup does not have any affect on your current 2-channel rig and it does not even need to be turned on when listening to music. To play HT content, turn on the HT receiver, select HT source, select ht bypass/processor loop on the pre-amp (or select the appropriat input if you do not have HT bypass). You will need to "pre-select a volume setting on the pre-amp (like top-dead-center) if you don't have an HT bypass crcuit and you will need to "calibrate" the HT setup. You will always have to set the pre-amp to this pre-selected setting when listening to HT or you speaker output calibration will not be correct.

This is much simpler than it may seem from this post. Of course, an HT bypass/processor loop simplifies the process because there is no need to "pre-select" the appropriate volume each time you engage the HT portion of the system.

I have used a setup like the one described in several different iterations of my 2-channel/HT combo systems. That said, I have now abandoned the combo setup and have simply built two competely separate setups (one for 2-channel, one for HT) that both sit on one audio rack. I placed relatively inexpensive "on-wall" HT speakers above/beside my Plasma TV for L/C/R HT speakers. These speakers are up and out of the way, so they do not affect the performance of my 2-channel rig. This may also be an option for you and it would have the benefit of not causing tube life issues for you when watching TV/DVD.

Here is a link to a picture of my current setup:

If you're considering the Avatar you shouldn't have any trouble piecing together a great HT/2ch system. My 2ch system includes a Denon 3910 player, Sim Audio I5 integrated, and Von Schweikert VR4jr speakers. When I'm in HT mode, the processing is done by an A/V receiver which passes the front two channels to the Sim Audio (bypassing the pre section) and to the VR4Jr's. Von Scweikert sub, center and rear speakers round out the 5.1 system. I have selected components that give me great sound no matter what 'mode' I'm listening in.

If you're looking for tube 2ch sound then the Avatar would be perfect for a HT/2ch setup. Get rid of the pre and amp and purchase a good quality HT processor/amp or receiver, center, surrounds, and sub and enjoy.
