replacing a processor

[chazman]

so am I understanding that if I upgrade to digital I will still be obsolete? That by the end of the year I will have to do this again?
Or will Dolby Digital be in the loop for quite some time still. I am sure I will be happy with DD for a long while (compared to pro logic) just as long as the DVD's will keep supporting DD for even longer!!

Yes and no. Dolby Digital will be around for a long time to come, just like Dolby Pro Logic has and still is on older programs and DVDs. The new formats are pretty much only included on HD DVDs an BlueRay. When will these become dominant like DD? Who can say but it is probably safe to say the time line will probably be similar to the transformation from DPL to DD.

This is why, in the long run, a preamp that is separate from the amplifiers is a good investment long term. I have not thoroughly researched which preamps now support the HD formats but you may be able to find a few but your selection will be limited until HD audio gains more ground.

Your equipment failure could not have been less timely as this transition period is just now becoming problematic. Some mfgs may be able to provide a modular upgrade solution but this is the exception, rather than the rule. I do not remember who makes this last pathway possible but I do remember reading something about it a few months ago.

I will do some digging if this last option interests you.

You're not going to get any preamp / processor and 3 channels of quality amplication for much less than the Adcom unit would cost you.

Not sure if I'd fix the old unit and add the Dolby Digital processor or not... With multiple reliability problems... Adding another component... Depends on how much you like it I guess... and if you're willing to pay if it needs repair again...

Aside from repairing your old Adcom, I agree that a quality receiver is probably your best bet on a budget. Make sure you get one with preamp outs for the main 2 channels. Not all receivers have them. Most of the better ones do. You will be able to use your outboard amp for the main two channels. It will take some strain off of the power supply in the receiver and improve power and sound quality to the remaining channels powered by the receiver.

I'm using a Harmon Kardon HT receiver with an outboard amp for the 2 main channels and I'm pretty satisfied. All of the brands already suggested here are good. Most receivers really aren't much more complicated than need be to properly calibrate home theater. Any outboard equipment will tend to have the same settings / adjustments. Keeping everything in one box, controlled by one remote keeps the system a little simpler IMHO. If you listen to several the brands listed here, you could probably find something to your liking.
