Not too impressed by that.
While I own the Anthem MRX-1120 and a couple of Paradigm subs, it's made me wonder about other offerings a little more. In all comparisons I have read it seems the reviewer preferred the Parasound amp to the Anthem. I am curious if you use the Parasound amp, and what experience you have had with it. I am always concerned about heat, so that is my primary concern. I think all the amps will power my 4 ohm speakers, but don't want to deal with an amp that heat related problems.
Thanks again for any help.
No, I do not use any Parasound amps in my dedicated HT room nor in my dedicated 2 channel setup room. But I 've heard those Parasound Halo A51/A31/A21 amps and they were wonderful especially for the money. But they run kinda warm I guessed partly due to class A biased for the first few watts. So if you end up with these Parasound A31 or A51 or A21 amps I would suggest you place them on the floor on the amplifier stand, or place it in an open hifi audio rack and leave a space above it. I wouldn't put it in a closed confined audio or AV rack if I were you. I would recommend these Parasound Halo A21/A31/A51 amps over Anthem amps.
However, the Rotel RMB-1585 five-channel amp runs cool at all time and is a fantastic multi-channel amp for both stereo music and surround sounds. My cousin has this Rotel RMB-1585 amp in his multi-channel setup driving his B&W 804 D3 speaker system. The RMB-1585 is massive though and weighs around 80 pounds. If you're worried about heat issue with those Parasound Halo amps then this Rotel RMB-1585 would be your best choice. It performs excellent especially for $3k brand new price. For surround sound movies the Parasound Halo A51/A31 perform better than the Rotel RMB-1585 amp. The Parasound sounded more resolving with better detiails and nuances and better PRAT than the Rotel RMB-1585.
But for music both the Parasound and the Rotel RMB-1585 are almost on par, you can never go wrong with either of them when used for music reproductions. The Rotel RMB-1585 runs cool no matter how hard you drive it. The Parasound Halo A51 runs somewhat hot.
In my dedicated HT room I'm using all Classe Delta series class AB amps to power all my speakers. Pls see my signature below. I'm using 3 Classe Delta CAM 600 monoblock amps to drive my front B&W 800 D3 and the B&W HTML1 D3 center speaker. And I'm using 2 Classe Delta CA-2300 stereo amps to power my custom theater (CT) in-wall surround speakers, which are also matching B&W 800 series D3 CT in-wall speakers. I'm currently only doing 7.2 setup since my Classe SSP 800 preamp processor is only a 7 channel processor and does not support Dolby Atmos, DTS-X or Auro 3D. The SSP 800 has become somewhat obsolete now but it's still one if the best sounding AV preamp processor.
I use this HT setup room strictly for surrounds or HT. I don't listen to stereo music in this dedicated HT room.
I do have a separate dedicated reference stereo setup/system in separate dedicated stereo listening room. Please send my signature below under stereo setup. For this reference stereo setup I have the Naim Statement NAC S1 linestage analog stereo preamp, Naim Statement NAP S1 monoblock amps driving my Magico M6 speakers.
For digital front end source components I have the MSB Select ll DAC with an upgraded Femto 33 clock and with 2 mono powerbases or 2 mono power supply units, one for digital side if thing and the other for analog side of thing.
For analog front ends I have the Clearaudio Statement turntable with a Statement Goldfinger cartridge and external PSU for the turntable. I'm using the D'Agostino Momentum phonostage preamp for the turntable.
