I just purchased a Marantz SR6007 AVR from my local B.B. store. I was actually looking for a Yamaha Adventage RX-A1020. I wanted to purchase something that could and WAS RATED to power some 4ohm speakers. Maybe even a 5.1 set up.
The Salesman told me that the Marantz SR6007 could handle that. Bu ton the back of the AVR it only lists 6ohm-8ohm's.
The Yamaha RX-A1020 says in the specs that it can go down to 2ohms. http://usa.yamaha.com/products/audio-visual/aventage/rx-a1020_black_u/?mode=model vs http://us.marantz.com/us/products/pages/productdetails.aspx?catid=avreceivers&productid=sr6007
I was wondering about the Yamaha not having the audio capabilities as the Marantz such as Dolby and DTS Decoders http://receivers.findthebest.com/compare/154-155/Yamaha-RX-A1020-vs-Marantz-SR6007
And some people say they like the YPAO better than the Audyssey MultEQ XT. What I have noticed about the Audyssey is after I run it, and I want to make a minor adjustment to the sound in the bass, mid, or treble ever so slightly, I am unable to just make that one particular fine tune adjustment on top of what the Audyssey MultEQ XT has set the sound at . I would have to turn it off and start all over and adjust the whole spectrum of sound from scratch. Is it possible to make that fine tune adjustment with the Yamaha RX-A1020? I will be using a 5.1 set up very soon here as son as I can figure out the proper receiver.
I am not really considering the Pioneer Elite SC-61 Series because I either here good or really bad about those Class D Amplifiers. And those are clearly rated for 4ohm speakers. http://www.pioneerelectronics.com/PUSA/Home/AV-Receivers/Elite+Receivers/SC-61
I was thinking of getting an amplifier that is actually rated for 4ohm speakers just to be safe and get a little bit of future proofing insurance. I'll be using it mainly for home theater use. But when music is being played it will most likely be rock, hard rock. Like Exodus, they have an album named Boded by Blood that just rips and tears. But it has to be played loud!
Your link shows incorrect information. Both receivers decode most of the surround audio codecs and all legacy codecs such as Dolby digital 5.1, DTS 5.1 etc. you just have to bring home both of them and compare side by side in your room.
You may use your tone controls the way you want after activating Audyssey MultEQ XT, but you can't use the built-in EQ additionally, because that is just the lower alternative to Audyssey, as it is just a simple EQ without the merits of Audyssey. Most of today's AVRs are handling the complete spectrum of 4-8 Ohm speakers quite well meaning that the lowest impedance value may even come close to 2 Ohm.
