I'm looking to get a new receiver that supports HDR content and I was contemplating the Yamaha RX-A2050. Does anyone know if that will have issues driving the Epic 80 Home Theater speakers? Its listed as a 8 ohms AVR.

Also in consideration is the Onkyo TX-RZ900.

Any help is greatly appreciate. Thanks

I would say look at what features are important to you between the two. You might want to look into the difference between YPAO and MultiEQ. I don't know which one is better. I have MultEQ XT32 on my Onk and I can't say enough good things about it. It tamed my EP600 and my room. It has great control over the M80s in my 4800 cubic foot space.

Thanks for the quick reply.

So in regards to it being 8 ohms that shouldn't be an issue?

The Onkyo is 4 ohms and another is their price range is the Denon AVR-X4200W which is also 4 ohms.

Not an issue but if there's a choice between a 4 Ohm and 6 Ohm (or higher) setting, choose the higher.

Ok. I thought Axiom recommends 4 ohm AVR's to power their speakers.

Nope. They do recommend a quality AVR though. I'm using an older Denon 2808 and it's not 4 ohm rated.

If you are referring to the 4 Ohm vs. 6 Ohm switch, setting to 6 Ohm doesn't defeat 4 Ohm operation. Setting to 4 Ohm defeats 4 Ohm operation. It's physics...LOL!

Welcome to Axiom. Amplifiers, including those in receivers, have to be rated in accordance with the FTC amplifier regulations. Among other requirements, at the rated impedance at least two channels have to be simultaneously driven for at least 5 minutes at the full rated power. This is a severe requirement which can be measured in the lab, but doesn't occur in home use. Receivers can meet it at 8 ohms but not at 4 ohms. There are no "4 ohm" receivers, such as you mention.

This should be of no concern in driving your Axioms, including those rated at 4 ohms impedance. Any quality modern receiver, such as those which you're considering, carrying the usual official FTC 8 ohm power rating can drive them to all safe(to hearing)listening levels.

So power isn't a problem, and your decision should be based on the features in the various units. In particular, of those you mention I'd suggest that you consider the Denon 4200 with the the highest grade Audyssey MultEQ XT32 setup and room correction processing(Onkyo no longer uses it and has replaced it with a cheaper and less effective in-house system). A good buy is at Accessories4less for the Denon 4200 factory refurb, which should be, if anything, even more reliable than a brand new unit.

That's a heck of a deal! Second only to my Onkyo TX-NR818 that I got new for $850 Can with some goodies thrown in.

Thanks everyone for the clarification...

The Denon AVR-x4200 and Marantz SR6010 were on my short list also... I narrowed it down to he Yamaha & Onkyo because they were Sound & Vision Top Picks. But you make an excellent point on the room correction software.

I saw recommendations for Accessories4less on AVSForum as well.
