vasubandu Posted January 15, 2018 Share Posted January 15, 2018 As soon as I can get a great deal, I am going to get a good receiver for my new home theater system. But the broken Yamaha RX-A850 was really broken, when sent me into the garage, where a Yamaha RX-V673 magically appeared. So my question is whether for the time being it is adequate for a system with RF-7, RC-7, RS-7 and SVS PB2 Plus. I don't need anything fancy, just want it to work normally. Here are its specs rated at 90W whathifi 5 stars avproductreviews "The Yamaha RX-V673 has tons of features and most who’ve purchased it have high praises for it’s sonic qualities and on screen GUI. If you can get it for under the MSRP I suggest you snap one up, you won’t be disappointed. Not doing Atmos now.

The History Kid Posted January 15, 2018 Share Posted January 15, 2018 Keep in mind, it's probably more around 50 WPC all channels driven. There aren't many, if any, that currently offer 100 WPC under the $2k pricetag. I wouldn't use any of the white-face RX-V models. They just aren't built like they used to be. Why are you stepping stones on your AVR? Particular reason? 1 Quote Link to comment Share on other sites More sharing options...
teaman Posted January 15, 2018 Share Posted January 15, 2018 Yamaha is famous for falsely over rating their receivers. I'm with Michael thinking that the actual output is closer to 50 wpc all channels driven. That is a lot of woofers you are trying to push off of one small power supply. I would seek out a better receiver from Accessoriesforless.com for that same money and give your speakers some extra oomph. Tim Quote Link to comment Share on other sites More sharing options...

No reason at all except that I have not figured out exactly what I want and was hoping for something cheap and used in the local market. An Onkyo RZ900 came up this morning for $400, but I missed it by half an hour. A4less is $900 for the 920, so I figured it was a good deal. If I spend real money on something, I want Atmos. And my candidates there are Pioneer 501 or 701, Onkyo RZ820 (but I prefer the 920) or maybe a Yamaha RX-A2050 when they get them again. Generally I would prefer to move up models and go back a few years as long as I get Atmos. This is an area where I really feel unqualified to pick something. So I had this old receiver that seemed marginally capable, but I was not sure. I find the Pioneers intriguing, but no one here mentions them. Not sure if that is chance or for a reason. I also read that different brands of receiver work better with different speakers, but I have found nothing about what works with mine. If I had that pinned down, the rest might be easy.

teaman Posted January 15, 2018 Share Posted January 15, 2018 The receiver should be capable enough to fill in while you shop for what you really want, just don't try to attain anything close to reference level with it...I don't think the results will be positive.

vasubandu Posted January 15, 2018 Author Share Posted January 15, 2018 @Ceptorman at this point, I would prefer to avoid external amps. It just does not seem like it should be necessary. So if Yamaha overstates power, then they are out. That would seem to leave Marantz, Onkyo and Pioneer if they are in. A4Less just has an amazing deal on the pioneer. They are a dealer. The 501 has a list price of 999, and they are at 450. $550 or more elsewhere.

With the Class D3 (Direct Energy High fidelity class D) Amplifier, the SC-LX701 is ready to meet the needs of the latest HD content. With our MOSFET, the Direct Power FET, this simple, high powered solution is provided to fully meet today’s AV entertainment standards. High-Power Simultaneous Multi-Channel Drive With Class AB amplifiers, driving all channels at full power is only possible for a short time, at around 300 W to 400 W power output. The SC-LX701’s Class D3 Amplifier has the ability to simultaneously drive 9-channels at 760 W power output, while managing to deliver dynamic content more efficently. I read this to mean that it has 760 watts available continuously. Maybe I am wrong. My confusion is preventing me from taking action.

Pioneer's power units are most likely between 50-75. Look at the power consumption of the power supply in the unit. That's a good indicator of what the unit is capable of. Every mainstream manufacture overstates it's power supply. The few that don't include Cambridge, Rotel and Outlaw. Quote Link to comment Share on other sites More sharing options...
vasubandu Posted January 15, 2018 Author Share Posted January 15, 2018 You know @The History Kid I have been looking for total watts and cannot find it anywhere. So if you were driving RF-7 i, RC-7, 2 RS-7 and 1 PB2 Plus, what would you want to be able to just hook it up and not think about power?

Download some of the manuals, they're always going to be presented in the manuals an manuals are available anywhere. Some print the total power on the back of the unit - they have to have it somewhere. Quote Link to comment Share on other sites More sharing options...
vasubandu Posted January 15, 2018 Author Share Posted January 15, 2018 Also, I have an APC H15 power conditioner with about 12 power outlets. Do I want to plug my receiver/amp into that? Quote Link to comment Share on other sites More sharing options...

The History Kid Posted January 15, 2018 Share Posted January 15, 2018 Wrong spec, you want to look at something called "Total Power Consumption" which is usually not where power ratings are located. Quote Link to comment Share on other sites More sharing options...

Those other 440 watts must be for the subwoofer, right? 1 Quote Link to comment Share on other sites More sharing options...

My old RX-V2700 was rated at 130wx7 and bench tested I think it put out 47 or something silly like that. Quote Link to comment Share on other sites More sharing options...
The History Kid Posted January 15, 2018 Share Posted January 15, 2018 3 minutes ago, vasubandu said: Those other 440 watts must be for the subwoofer, right? No. A subwoofer lineout does not have any powered output. While it's likely that the Pioneer puts out more than 50 WPC, it's likely never going to exceed 60. Not a meaningful increase over the Yamaha. That's why a separate power amp is recommended. Quote Link to comment Share on other sites More sharing options...
vasubandu Posted January 15, 2018 Author Share Posted January 15, 2018 Well at least Onkyo is an honorable company. Their RZ920 pumps out a kickass 175 watts per 9.2 channels. And the amazing thing is it does all that with 310 watts.
