98thumpin

ok i will be using a onkyo TX-SR804 as my reciever for my home entertainment system. it will be the pre amp for my monitor 70's from polk audio,
what i need to know is what would be a good power amp for these monitor 70's series speakers the onkyo is a 7.1 channel reciever makes 105 watts per channel
sounds good but with more power i think it would sound better,

whats a good power amp? and what wattage rms should i look for.

Several others on the 'Gon, so now might be the time to barter and plead.

The two make a great pair (or threesome, I suppose). Plenty of slam and more than enough power for the 70's.

98thumpin

allright price looks good but how many watts rms does it make?

zombie boy 2000

I believe 135 into 8 ohms and 220 into 4 ohms. More than enough for the 70's.

98thumpin

i was wanting about 200 watts rms going to the 70's 200 watts each

Schwingding

You are correct about more power making them sound better. The 70s are large speakers and relatively inefficient at that. I would like to suggest that you take a look at the Outlaw amps. I have purchased 5 of their 200 wpc monoblocks and they do whatever I ask of them. While I may one day upgrade to higher end amps, with this range of equipment that I have at present, I will have no need to replace them at all.

ok thanks for the suggestion ill look into that brand the monitor 70's are recomended to be powerd with up 275 watts im thinking 200 rms would do good am i right about that

zombie boy 2000

If you insist on 200 wpc on the cheap, then I might recommend an Adcom 555 for $300-350 used.

I have an extra Adcom gfa 555 mk 2. I would sell..PM me if interested.

98thumpin

i know nothing about adcom; id like a name im familer with, yamaha, sony, jvc, onkyo, denon, etc

zombie boy 2000

None of the companies you mentioned make a two-channel amp that I can think of... not recently. With the exception of Onkyo, but I believe that model (282?) was discontinued. And that was only around 100 wpc.
Search "adcom" or "rotel" or "acurus" and see what you dredge up. Once you're familiar with the names, we can get back on track.

Other than that, you'll be chasing your tail in trying to score a 200 wpc JVC two-channel amp. I believe that unicorn flew away once he heard saskewatch was hot on his trail.

Zombie boy is right.
Do some homework. You're gonna find that you are going to have to branch out with other company's other than mainstream in order to get a decent amp. Get used to it because this is just the start. The deeper you get into this hobby you will be exposed to companies that you have never heard of that make Killer equipment!

Try the CineNova amp at 1000 watts per channel.

the 555 is hard to beat for the price

98thumpin

do you know what the true rms of the 555 is, i want 200 watts rms per channel

98thumpin

oh ok so the power they, IMHO, Adcom, Rotel, Nad, Carver, list should be the true rms.

Ern Dog

IMHO is not an amp- it means "In My Honest Opinion."

If you can listen to some of those that would be a good place to start, also read some expert reviews and people's reviews/opinions on this forum. Use the "Search" feature on this forum to do a search of what others have experienced using these amps.

98thumpin

ok i will

98thumpin

i went today and listened to the rotel amp it was awesome im considering either the rb 1070 or the rb 1080 to runlk my polk monitor 70's

98thumpin

im leaning towards a the 1070 with 130watts rms per channel, that would be good for the monitor 70's wouldn't it

98thumpin

is the rb 1070 or the rb 1080 capable of bi wireing?

98thumpin

i havent been able to find a picture of the back of the 1070 or the 1080, and the drawing i saw only should 4 binding posts wouldn't i need 8 of them im not to familer with bi wiring but i know i want to do it that way

98thumpin

oh ok which post is for the highs and which is for the lows? might just be my simple mind, but if you connect two wires to one post arnt both wires getting the same signals, or does the speaker seperate the highs and lows from the wires?

98thumpin

well that did help some

98thumpin

well i know how to bi wire now, do you know what the monitor 70's can handle continiously can they handle 200 rms
