Thoughts on Marantz AV8802a vs Rotel RSP 1582


OK so I love both 2 channel and HT and am building my little man cave and need a good pre/pro for both.  The two I have narrowed it down to are, as the title reads, the Rotel and the Marantz.  The Marantz has the definite edge with the latest HDMI, but according to Rotel they have, or will have the upgrade any moment.  Any strong opinions for either?  The rest of my system is listed below.  I have some inexpensive Klipsch surrounds I will probably hook up for ATMOS but 2 channel is REALLY important.  Thanks in advance........

"I think using a typical 2-channel preamp is a mistake, because it does nothing to alleviate room effects. The room has the largest impact on sonics, so why not address that?"

That's not good advice. One thing has nothing to do with the other. A 2 channel analog preamp isn't supposed to have an effect on room acoustics, or do any signal processing. In fact, that's exactly why it was recommended in the first place. Providing the components in a system are matched reasonably well, the preamp usually has the biggest effect on the sound that comes out of the speakers. There's better ways to deal with room acoustics than run a perfectly good audio signal through a bunch of crap. Process HT only. Not only that, we don't know anything about the OP's room. Maybe it doesn't need anything.

"Note, you'll also lose bass management when using a 2-channel preamp and speaker level matching and distance delays"

Good. There's no reason for bass management in a 2 channel preamp. If a sub is added to the system, you use the xover in the sub itself for bass management.

Before this turns into a long, senseless argument, consider this. When you go to shows like CES, NY, Rocky Mountain, etc..., how many high end displays use bass management? With exceptions for odd brands like Tact and Meridian, none of them do. In the last 25 or so years, I have yet to see 1 setup that employed bass management.

Excellent info thank you.  My room is small and probably not ideal for acoustics.  It is a detached 2 car garage that I have converted the front half into a man cave.  The back half is a home gym and separated by a curtain.  leather couch and large rug in the front.  The half I use for lounging is 18x12.  The seating position is a little over 12' from the speakers.

I hadn't considered a separate 2 channel pre due to cost, but now I am intrigued.  

Please keep suggestions coming and thanks again to everyone who posted.           

"My room is small and probably not ideal for acoustics. "

Few rooms are. We all have rooms that are not perfect. That said, I see nothing about your room that should pose any major issues. If a problem does arise, it can be fixed acoustically without spending a lot of money.

"I hadn't considered a separate 2 channel pre due to cost, but now I am intrigued. "

Here's a good article on the subject that goes into a bit more detail. It starts on page 4.



To reinforce mgreen's position, serious 2 channel HiFi and HT stuff are two different worlds.  And the biggest difference is usually found in the stereo preamp section of a good HiFi system.  The preamp section in an AVR or a TOTL pre/pro like your considering is merely an afterthought even in so called "pure direct" mode.   

After a 12 year affair with the HT mistress always being left unsatisfied with music, I returned to 2 channel only and couldn't be happier.  And that was using a variety of flagship AVR's and HT separates. 

But these two worlds can be easily and elegantly be brought together by use a stereo preamp with an HT Bypass feature.  You can still use your Rotel HT amps in this configuration.  This is why I so quick to suggest one.  And you can now pick the pre/pro that you want without worry of which will be best for 2 channel as neither really will.

OK  so it seems pretty clear a 2 channel pre is in my future.  Any recommendations on units with the HT bypass and a cost of less than 1500? I don't mind going used.

Again thanks for the great advise
