Should I use pre-amp outs on RX-V2200

[surveyor]

I have a Yamaha RX-V2200 reciever that's rated at 100 Watts x 6 channels, and has a pretty decent power supply. The unit weighs 33lbs. Two of my stereo amps are rated at 200 Watts at eight ohms. My third stereo amp is rated at 225 watts at eight ohms, the amps are of decent quality and sound very good.

My questions follow:
1.Should I use my recievers pre-amp outputs to the three stereo amps that I already own?
2.Is this just a waste of effort as the RX-V2200 amps do not seem to be a slouch at all?
3.Will I loose any tweaking features available in the Reciever, if I do this?
4.Is the pre-amp on the RX-V2200 of high enough quality to warrant this?

Cheers

By all means try it, you will not loose anything and may gain better sound if they are better amps. Use the two matching amps for L,R,C and the odd amp for the rear, Recalibrate your levels and you should be all set. You might be in for a surprise as I was. I did this with an Adcom 5 channel amp I had, and I found out it did not sound as good as the receiver, but depending on your amps your results may be different. So do give it a try. If you find out they are not as good or no better, then use them somewhere else or sell them and buy a new DVD player or take your girl out for a night on the town

or in answer to your questions
1-Yes
2-Maybe
3-No
4Yes

Thanks for the informative reply jeff!
I'm going to give it a try. I'll be busy with all the wires and WAF, as the home theatre set up is in the living room and installed in an entertainment center.

Should I use pre-amp outs on RX-V2200 Update

Jeff and any one interested. I am now using the pre-amp outs (main and rear surround) to my amps. I new that Yamaha pre-amps were good, but I'm stunned at what an improvement this has made in my humble system.
Yamaha is as good as AudioHolics says! I must say that even a blind hog gets an acorn every now and then. To me the sound of the system since the change is as good as Jenifer Lopez looks! Please do not mistake that I think that my gear is as good as a lot of you AudioHolics out there, but my gear is much improved!

Hmmm.. if you took the preouts of the Yamaha, fed them to your other amps and got a perceived improvement sound, I think that's more a credit to the external amps than to your yamaha, right?

Good Point But

Your point is definitely not wrong, but the pre-amp that I was using on the stereo amps before was not cheap. The cost of it in 1991 was $1,200. The RX-V2200 pre-amp suprised me in a positive way.

But lets dissect this a little more shall we? what was the source you were using on the old pre-amp and what is the source you are using with the Yammie, If you are letting the yammie do the decoding and you were using some other CD player, then that is likely what you are hearing as the difference in sound. Starts to get a little ridiculous don't it

 

[surveyor]

What was the source?

Jeff, the source is the same multidisk player. The only change is the addition of the amps.

Cheers

 

[jeffsg4mac]

Yes but how did you have the CD player connected to the Yammie? Were you using the fiber optic or coax digital or the analog section. If your were using fiber or coax digital then the Yammie was doing the cd decoding and not the CD player. So then you might be hearing the better decoding of the yammies proccesors?

Pre-Out on Yammie

I agree with AV Phile. Surely if you are using the pre outs on your Yammie, and the speakers are connected to the new amplifier's terminals, then the improvement in sound is due to the added amplification? The Yammie will still be providiing pre-amplification stage, which is critical also...

Yamaha Pre-Amp

The connection was fiber optic from the multidisk player to the RX-V2200.

Ok here is my point, when you were using the old preamp you were using the analog inputs, so the CD player was doing the decoding, when you switched the amps to the yammie and used the fiber connection the yammie is doing the decoding, so you might be hearing the difference in cd decoding not the preamps. My point is this, it is not likely you would be able to hear a difference between the preamp sections of two good preamps. It would be very subtle if at all. However, I do believe you will hear the difference between the yammies amps and your other amps. What are they by the way?

 

[surveyor]

There are three amps total.
They are listed as follows:
2 each Carver M-1.0T (These amps are each bridged to Mono and rated at 1000 Watts each Continuous Sine Wave per channel (RMS)).
1 each Carver TFM-24 (Stereo it is rated at 225 watts Continuous Sine Wave per channel (RMS)).

I should add this.
My front right and left front speakers are Precise Acoustics Monitor 10 and the manufacturer recommends that they be used with an amp no less than 150 WPC RMS and recommends 300 RMS WPC. The M-1.0 T amps power my front left and right speakers. The TFM-24 is powering the rear surround left and right speakers. I'm using the Yamaha to power the front and rear center speakers.
I understand that there are lots of people that feel that Carver Amps are not audiophile grade and lots of people that do feel that they are of audiophile grade. Please spare me the argument on this, as I already have them and do not wish to spend money on other amps.
The aggument of wheather the Yamaha's DACs versus the Multidisk DACs are the reason for improvement is acknowledged.
