I've been wanting to get into separates for HT for a long time. My goal was to buy the amp(s), then buy a pre/pro. However, I would want a pre/pro that has the latest new HD format decoders on them. Some of the latest receivers have them, and they can be had on-line NIB for as low as $600. A pre/pro with these decoders is likely to cost a whole helluva lot more than that, which would probably be too costly for me. My budget is a max of $600. I was originally thinking an Emotiva, a used Outlaw, or something like that.
So here are my options:
1. Do nothing. Cost = $0
[NOTE: I have an older receiver, 2-channel amp on the fronts, other speakers driven by the receiver.] Sounds fine to me.
2. Buy amps and use same receiver for a while longer until the used pre/pros with the features I'm looking for hit the market in my price range in another 12 - 18 months or so.
3. Buy amps for other three channels and "upgrade" to a newer receiver with HD formats.
4. Just buy a monoblock for the center channel and be happy.
I'm leaning less towards options #2 & #3.
I've had separate amps before on all speakers, but I've never tried an HT pre/pro.
