Hi Current AV reciever

[fyrmedic01@hotm]

I just purchased a Yammie v-1500. I really like all the bells and whistles..I have dynaudio 4ohm loudspeakers....While I have not had a problem driving these speakers..They really do not come to life untill I have it turned up quite loud...I had an older Marantz that drove the speakers but had only dolby digital...I am willing to spend a little more but not too much. Which begs the question.. Watts VS Current...I have dynaudio 52's for L/R and 122c center, and mirage Omnisat micro's bringing up the rear..Any recomendations for AV recievers with good Watt/Current output that can compete with the Yammie for decoding.

The RX-V1500 really isn't meant to drive low impedance, low sensitivity speakers such as the Dynaudios you own. The most cost effective solution would be to add external amplification and use the RX-V1500 as a pre/pro.

AV123 makes a phenominally good 7CH amp called the MPS-1 for $2k that will drive your speakers with no problems.

he said he didn't want to spend too much more......$2K?

or does the Marantz have pre-out inputs ? maybe you could feed from the Yammy into the Marantz for your front channels ??

Either keep the Yamaha and by an external amp to drive the Dyn's or return the Yamaha and find something that can drive the 4 ohm load. NAD and Rotel receivers can drive 4 ohm loads with no problem possibly the Denon 3805 but I think it was intended more for 8 ohm loads. However the best thing to do is save for external amps. This will give you the current you need. Dyn's need alot of it to sound there best.

Which begs the question.. Watts VS Current...

For a given impedance (speakers), higher current invariably will yield higher watts. Further, two amplifiers, each capable of delivering the same power (watts) into say, and 8 ohm load, will have to pass the same current.

A lower impedance load, e.g. 4 ohms, will draw higher current than a higher impedance load, e.g. 8 ohms. So high current capable amps should generally be able to drive 4 ohm speakers.

For receivers though, this does not seem to be the case. H.K. receivers, for example have high "instantaneous" current capability, but they still only rate their receivers with 8 ohms loads. Perhaps "instantaneous" is the keyword here, as we all know, instantaneous means very short duration. This is not to say that receivers such as the H.K. AVR635 and the Denon AVR3805 cannot do it, but if you want to be completely worry free, stick with NAD or Rotel.

There is a rotel dealer near me. the dealer I purchased the yammie from also carries Arcam???...I am a little confused on reading specs...if someone has the time to go to the arcam website and tell me if the arcam can run 4ohm loudspeakers..If possible I would like to keep it to an AV reciever just because of room...I know seperates would be better...what do you folks know about rotel??? good/ bad?

I just went there and downloaded the handbook. The AVR300 can do 100W X 7(1kHz at 0.2% THD) 4 or 8 ohm. I auditioned the AVR300 last year, it is a great and sweet sounding receiver. It powered the relatively inefficient Energy Veritas speakers to very loud level with no problem at all. I went with the Denon 3805 in the end simply because I thought the Denon offered better value for the money, and I already have a 2 channel power amplifier to take care of the front L/R channels.

On further reading, it turns out that the ARCAM has an impedance selector switch. That explains why they do not give a higher output (watts) when driving a 4 ohm load. The selector switch would likely drop the d.c. rail voltage in order to limit current (hence watts), to avoid the receiver shutting down. If this is the case, it would still have to deliver higher currents into a 4 ohm load in order to maintain the same 100WPC output, but not as much as receivers that do not drop the d.c. rail voltage.

Is that 100 watts at 4 ohms and 100 watts at 8 ohms? If so, it is not very high current at all.

mtrycrafts, I just edited my post. You're right, seem like they limit the current. Based on the specifications, I would put the AVR250 in par with the HKAVR635. Difference is, the 635 does not have a 4 ohm switch, so you either do the 4 ohm thing carefully (not too loud for not too long) or stick with 8 ohm. With the ARCAM, use the switch, you are safe. If you want the power to approach double, or 1.5 times down, then go Rotel, B&K, Adcom, or separates...........

Outlaw Mono Blocks

Outlaw Audio makes some very nice 200w mono blocks that would work well and only cost 299.00 each. They also make some nice multi channel amps for under a grand. outlawaudio.com

That's only a two channel amp. He needs to drive all his surround speakers at 4 ohms. Try the new Harman Kardon 7300. It's pricey, but it puts out massive current to all 7 channels. No other receiver in that price range even comes close. I think Sound and Vision Mag has a great review on it. Much cheaper than buying any 7 channel separate amp.

 

[fyrmedic01@hotm]

Thanks I will look in to all the suggestions.

I have the NAD T752 driving 3 Dynaudio 42's across the front. From what it sounds like you are having about the same experience that I am. I am always feeling like I need more power even with a NAD receiver. It sounds like your Yamaha is producing similiar results as I am getting with a NAD. I am looking into gettting the Outlaw Monoblocks myself for the front 3.

It is kind of hard to tell you to get another AV Receiver with the chance you still might not be satisfied. I would suggest getting external amplification with your current receiver.

Hope this helps.

 

[fyrmedic01@hotm]

This is a stupid question but does the outlaw monoblock only run one speaker? Two channel mean two speakers or one????

 

[anamorphic96]

Yes it does mean one channel. But when you consider the price of 5 it comes out to the cost of a 5 channel amp. However the nice thing with Outlaw is you buy 2 and then add more as time goes buy. But they also cary some nice 7 channel and 5 channels amps. Check them out. outlawaudio.com
