Axiom Home Page Forums General Discussion Technical Questions Amp Question (4ohm stuff)

Now that I have decided on the M80, I need to revisit amps. I was poking around on a couple of sites including Denon, and didn't see anything in the specs about handling 4ohm loads or power output at 4ohms.

I still really like the Yamaha RX-V663 on paper as it delivers all the features I want (and not a lot extra) at an attractive price, but I don't dare buy it unless I can see a credible review suggesting it will handle the M80s.

Denon seems to be a little behind on the new HD audio formats.

The closest I can find would be Mikes review of the 661

Denon has been one of the recommended receivers for m80's for over 5 years now. I have the 2805 and many have older models with no problems driving the 80's to sonic bliss.

really? my denon decodes every hd audio format known to man.

Denon's not lagging, they just expect you to pay more for the same features. The lowest Denon to have the HD audio formats is the 2808 and it has been on sale around here for $800.

I would be willing to bet next years group of Denons to have all the audio formats as well, or they will start to lose market share.

Rick. From what I have read the 661 power supply is not all that beefy. From what Tom Cumberland said, Yamaha is real hit and miss because the keep designing their amps from scratch for each new series. Looking at the past is no indicator. Look at the 659. It got rave reviews all around, but the 661, a newer receiver ended up with a lesser amp.

Denon, on the other hand, does what the Japanese do so will, incrementally improve each generation.

I know the Denons will perform admirably. #1,300 for the 2808 is a little more than I wanted to spend, particularly since I am stretching my budget already to get the M80.

I guess I am looking for alternatives.

What is it that allows or prevents an amp from handling 4ohm loads?

Fred, like Jason said, you can get great deals online for Denons.

Terzaghi. OK, missed the HD audio on the 2808, but let me put it another way: $600 for the 663 for all the features I need vs $1,300 for the Denon 2808. Thats a huge gap.

All those great deals are south of 49. On Denons I get the privelage of paying a $200 premium over you guys using a dollar that is worth just as much as yours.

4 Ohm speakers require higher current out of the amp. All amps can handle 4 Ohm loads provided they are not asked to drive too hard for too long.

If you're sitting 8 to 10 feet away from your 80s, you won't need more than 1 Watt to achieve 85+ dB. That leaves you plenty of power with this Yammy for the majority of material out there.

Oh, I never realized that denon did not include the HD audio formats in there 'lower end' receivers... kind of a bummer.

The 3808 is a great receiver (currently one of the best in its price range in my opinion), but I have to admit if I was planning on spending $600 on a receiver there is a lot more competiton.

I have mentioned this several times as well: call 6ave.com and ask them over the phone how much there denons are (hell ask them for other brands as well.) They have been selling all of the denon receivers several hundred dollars below MSRP.

Edit: I am not sure if these deals apply to canada or not.
