I currently have the Artison Portrait LCR Speakers hooked up to my Marantz SR-7012, my question is, is it worth it to buy a 5 channel AMP, or is my Marantz doing a good enough job powering these speakers? I currently have 9.2 setup. I was looking into the XPA-5 Gen 2 AMP, but also thought I have no need for the XLR. Any help or suggestions would be appreciated. Oh my Artisons speakers also have a presence switch, should that be to the on or off position? Not sure what that is for. Below are the specs for my Artison speakers.
Type: Bass Reflex Woofer: Two 4.5" polypropylene midranges Tweeter: 1" stage tweeter Tweeter: Two 1" Vifa soft dome tweeters Frequency Response: 80Hz – 20kHz (+/- 3dB) Nominal Impedance: 6-ohms Cabinet: Black anodized aluminum Sensitivity: 88dB @ 2.83 volts, 1m Recommended Power: 75-150 Magnetic Shielding: No

The XPA-5 has unbalanced RCA too. So this amplifier could do nicely for you. No one can tell your how your settings should be. Room acoustics and personal taste come into play here. The XPA-5 is an excellent amplifier for all reasons and all seasons.

Probably alters the loudspeakers response from nominally flat. Try flipping it on/off while listening to see if the sound gets brighter. The correct setting is the one that sounds best to your ears from the “sweet spot” Bill

One of the tweeters is side firing so I would turn that off (presence off) as I think that feature may fight the surround sound format (especially Dolby Atmos). They are 6 ohm and 88db, so a bigger amp might help.

The SR7012 has a fairly decent power amp (I had the SR7009 previously), so I don't know if you will see a huge difference going to the XPA-5 at most volumes levels. Where you will see a difference on the XPA-5 is if you listen to the volume fairly high, then you will notice the sound to be somewhat cleaner since the XPA-5 just has tons more power reserve than the SR7012 does.
The good thing about buying the XPA-5 now is that the amp can stick with you for years and years even as you change main units. I started with the SR7009, then I added the XPA-5 then I added an XPA-2. Eventually I went all external power and went with the AV8802A pre/pro. The biggest jump in SQ is when I went from the SR7009 to the AV8802A. But to get to that point I had to have all external amps ready to go. My point is there is no downside (except cost) in adding the external amps now as the will give you flexibility for upgrading in the future.

They are 6 ohm and 88db, so a bigger amp might help. I never thought that it would mess with the Dolby Atmos. I will definitely check and do a sound check as Bill suggested.
