How much power

417 Views 17 Replies 6 Participants Last post by  hodgjy
I have an old Interga 8.9 with 150 w and the HDMI out board "Gone" So need a new AVR....
Now here is my problem my speaker are Energy Veritas V2.2i , 8 ohm 89 dB sensitivity...I use then at higher volumes ..Old and hard of hearing ,,some LOL...
SO how much watts do I really need ???? Speaker book says "Recommended Amplifier Power 150 watts "

I am using 5-1 system bit will go to a 5-2-2 with this new AVR

Ideas ??? and do I wait for the new HDMI 2.1 to be out ??? about 50% Music and 50 % Movies and TV...

The difference between 150 watts and the much more common 100 watts is 1.8dB.

I’d find a solid receiver of any sort that has all of the bells and whistles you seek, with no regard to wattage as all of them will play to pretty much the same loudness.

What is your budget and is your preference for separates or an AVR? What is the volume of your room? What will you be using for your height speakers?

18 X 20 eating area with 18 X 30 room size, now sure on speaker just good ones and the budget, well all that I need.. or up to $2500. if needed
I would check out SVS Elevation speakers for your height speakers if you aren't looking to put holes in your ceiling. I own four of them and can easily be mounted right up against the ceiling on your sidewalls or mounted on the ceiling with the brackets. When ordering you specify which mounts you need. As for the AVR you should do fine with any watts between 100 and 150. As the previous poster mentioned you won't be getting much more decibel jump between 100 and 150 watts. Integra 8.9 was actually 140 watts but of course that was with only two channels driven. If you like the Integra sound without the price upgrade you could try the younger brother Onkyo. Very good bang for your buck. I personally prefer Denon and Marantz as I find Onkyo to be overly bright and less musical. Find a local demo room and go listen to the various brands yourself. You have to like the sound.

Thanks. What do you think about waiting for the @.1 HDMI stuff ???

I think we would all never buy anything if we kept waiting for HDCP 2.x or HDMI 2.x . Find something that sounds enjoyable to you and have fun.

HDMI 2.1 from what i have read on different forums is expected around summer next year so will probably be a while.

With a budget like yours it would be a good idea to go for one of the upper models from marantz/denon/yamaha possibly onkyo. There is more difference then just the one or two dB max volume increase between a 100w reciever and a comparable 150w one. The bigger one will have a more robust powersupply for one, which is very important in order to be able to deliver the current needed. You are used to a more capable AVR and will probably be dissappointed by the sound if you cheap out on a new one especially since you dont need to.

You make some great points about the sound quality the OP is used to with his Integra 8.9. It is from 2009 so maybe a midrange from Denon today might compare to the Integra flagship from 2009?

Depends on what you consider midrange but older quality AVRs were pretty powerful with sturdy powersupplies, so a midrange probably wont match it on that, but new formats and processing have come a ways.

I was thinking the Denon 4500 as a midrange option.

You'd be surprised just how loud 2 watts can get.

Without knowing about your room, it's tough to recommend how much power you need. Can you give us a description?
My seating area is about 18 X 20, in a room that is !8 X 32.. just open room, Open windows , with fire place on one end and kitchen on the other..
I do like good quality sound, so I do think a better AVR...Ideas

and thanks for the answers so far....I like my speakers BUT I am going to add 2 height speakers and I think a new bigger and better sub.. .....What do you like in the sub area??? thinking 12 - 15 inch..

Yes, the older receivers were very stout, strong power supplies and room filling sound. I do agree that, although they have many features, the newer mid level AVR's wouldn't hold a candle, power wise, to the older stuff. I think something like a NAD T758V3 or an Anthem MRX 720 (a little pricey?). Maybe a Rotel RAP-1580. Cambridge Audio makes some nice stuff, maybe a CXR-120? The fun begins! Go out and audition a few and let us know.

For sub advice head over to the sub section. (Couldnt help myself sorry) A lot of people there with a good grasp of whats availible for any need. A quick look at popular brands there includes svs, rythmic, hsu, monoprice monolith and vtr. (This is from memory so may be faulty or incomplete) usually brands that focus on subs are better performance/$ then speaker focused brands.

Consider 2 subs, its easier to get more even bass that way and each sub doesnt have to work as hard, but one can do very well also if more practical/WAF.
Also consider some are perfectionists there but it can still be very nice without everything being perfect. (Not many have the option of perfect placement)

Very good memory for the selection of Subs. There are some more upscale ones but there is some great subwoofers from the brands you mentioned. Two subwoofers could help in making the bass more even across the space.

Just my opinion....150 watts is more than enough for your space. Probably even 100 watts, as long as it's clean power. Onkyo has lots of good clean power, as does Denon (same parent company). You'll want 2 subs for sure, 12 inch may be too small to rumble the floor. Set your crossover at 80 or even 100 hz, which will relieve the receiver of some heavy lifting, and you'll have plenty of headroom with 100 watts per channel.

You can play around with this calculator a bit:

You'll see that 25 watts will be ear-splitting loud. For comparison, I usually listen to music and movies around 75 db, and that only requires 0.2 watts in my room.
