Chorus 1 more power

Chorus 1's

 

Hello I have had my chorus 1s since new in 1990 I run them on a yamaha ax930 intigraded amp rated at 130wpc Continuous but I'm looking to upgrade more of I want to wake em up I'm looking at a anthem mca 225 gen 2 power amp il the chorus can Handel 100rms and 1000 peak the anthem is rated at 225wpc continues really I'm just looking for reviews on people who have chorus 1s or 2s on a 200watt + rms amp and wanted a review on what I can expect once I hooked up to a more powerfull amp my 930 at 130wpc drives em pretty good but about half way on the volume nob they start to destort due to the amp running out of power.

I have not owned or even listened to either amp. After a quick search, it appears the Anthem costs 10x as much. Only your ears know what you like, and ABing equipment is the only way to find out what you like best. I can say that sometimes less is more. Often, a low-watt something will sound larger than most AVRs. On the flip side (for maximum loudness), it's best to have 2x to 3x the power needed to keep the speakers from clipping.

Yeah, it's best to not do that.

 Experimenting with my Sunfire amplifiers back in the day I found that the 200wpc Cinema Grand could not fully drive my Chorus II's- it could get them about I'd say 80% to full volume? Switching to the Sunfire 300wpc amp I could seemingly max out the speakers before the amp so I concluded if one wanted to get the absolute most out of the Chorus line a 300wpc rms amplifier was needed. I also used the Sunfire 400, 600 and 625 amplifiers and the speakers would get louder quicker but not louder overall than with the 300.

Woofers and tweeters ya I don't go near the half way on the amp at all ik distortion can hurt then I normally to 1 third of the volume and there loud as hell there with no distortion I'm looking to get them on a stronger amp so I have the head room if I wanted to crank em bit louder plus I want them to sound cleaner

Only thing with the sunfire amps is there not in my area sadly I got mcintosh but there verry expensive here in Canada really all I have in my area that I can afford rn is rotel or anthem.

@hibbs79 lately I’ve been running my Chorus with Phase Linear 400 or a Belles 400a. Both 200wpc. I’m not sure how loud they’ll go before distortion, but the cleaner the source the louder they’d be before distortion.

Will  more power matter.  The Chorus speaker is 101 db efficient or 1 watt - 101 db at one meter.  The difference between an amp with 100 watt vs 300 watts is around 4 db.  Not much, where are the watts?  To appear twice as loud you need 10X the power.  A 1000 watt amp would be twice as loud as 100 watt amp.  Really pushing a Chorus, max spl 121 db can't be listen to for over 15 min. without hearing damage.  What is the goal or is the sound dull or not as lively as you would like O.P.  

 

My RF 711's were 101 db and used for music and HT in a 800 cu ft. space.  I would frequently run my HT at reference level. Amps  rated up to 270 watt all 9 Ch. maxed out.  Eight 18 in. subs with 3000 watt amps. Some times I forgot my 40 watt tube amp was running the mains. The mains kept up with the system. The tube amp coasted thru reference level session without a blink.  Did I need a higher watt amp for the mains?  As far as headroom, a 40 watt amp was sufficient.

Since you've had the same speakers since 1990, two things have probably changed, your hearing and aging components in your crossovers. They may be the reason you think you're speakers need to wake up.

And a 35 year old integrated more than likely needs some freshening up.

 

I have had some low sensitivity speakers in the past, none of them failed to "wake up" with a good 100 watt amplifier.

Basically I want to have more headroom so if I ever cranked em louder they would be clearer sounding.

No they only have mabe 100 hours on em I played em alot when I go them but didn't really play em verry much when my kids were growing up just over the past year or two I've started cranked em again and they still sound as good as the day I bought em I juts want to get em on a stronger amp so I have the headroom of more power

[82 Cornwalls]

So you think less than 3 dBs is going to get you that headroom?

Sitting 2.5 feet closer to your speakers would gain the same, try it.

If I had 130 watts/ch and wanted more headroom I wouldn't even consider anything less than 500 watts/ch.

 

Keep in mind you would need 1,300 watts to be twice as loud (10 dBs) as 130 watts.

How is the amplifier going to clip if you have the power you need?

Yes ik they won't be any louder on a more powerfull amp I'm only looking fore cleaner power and clear sound I there loud as hell already and I verry rarely have em cranked to the point where ur ears are hurting

I would think a properly functioning amplifier over 100 watts would give you that.

Maybe try a Fosi Audio V3 with a 48v power supply (buy and return if you don't like it) or something similar for $100 to compare to your Yamaha.

The Yamaha is old enough I wouldn't use it as a reference point unless at a minimum the power supply has been rebuilt with new caps.

Only thing is I only like the sound of class A amps I've tired calss b and d and didn't like the way they sound my 930 still sound awesome and gets em loud as hell I'm keeping tge heresy 4s on tge 930 and want a more power full amp for the chorus the anthem mca 225 is a class a/B with 225wpc rms plus its in my price range of 3k if I had the money I would go with a mcintosh amp but the one I want is 21k and Il never own that I want a good clean powerfull amp I was gifted a wimm ultra for my b day about a month ago and love it I'm gonna use that as my pre amp I've herd good things about the fosi audio amps as well v3 amps.

[82 Cornwalls]

Your Yamaha is class AB.

You think your Yamaha still sounds awesome, but you don't really know if it performs the way it did when new (not likely given its age).

Now I'm getting the idea you just want a more prestigious amplifier, not neccesarily one that will actually make a true difference in how your system sounds.

Ya my ax930 was the most powerfull intigraded amp yamaha made back in 1990 it seen very little use pob only 100 hors on it only thing I had 2 do to it was get the signal board changed it blew a channel once but it's pretty much all original the guy who swapped the signal board for me Siad he coldest belive that it was in such good shape all the internals are in good shape but it's over 30 years old now and I want somthing newer but il never sell the 930 my hersey 4s sound awsome on it so the 4s are staying on the 930 and the chorus will get the power amp

Ah I just looked at a picture of the back, an impedance switch and a 6 ohm minimum speaker impedance.

What do you have yours set on 6 or 8 ohms?

I got it set to 8 ohms the amps a tank it's got two 22000uf capacitors in it iv always left it at 8 ohms
