Advice on new LSi9 3D set up

drd

Hi all - I bought my 2 LSi9's, 1 LSCi, and 2 LC60i's for ceiling rear surrounds (90db not 88 like LSi9's) in 2005 and have been powering them for TV and Music with the NAD 744 50wpc continuous 5.1 channel ever since. I don't listen at very high levels and the NAD has been fine I think; but most of you say I should have more power?

I just purchased a Panasonic 3D 65GT30 and Blue Ray 210 and I have an Apple TV, all of which have HDMI's which the NAD 744 does not. Soo I have been considering the 40 pound Yamaha RX 3000 140wpc but only about 76wpc with all channels driven. The reason I'm considering it is because its a 7 channel and could be biamped to front LSi's and its about half price ($899) now that it is being replaced by the 9 channel 3010 at $1899. And I've red that the Yamaha'a are very reliable.

All the specs above are in 8ohm not 4 ohm.

Is this going to have enough power to make the LSi's sound good?? Dick

Nope, go with dedicated amps. That Yamaha will run very hot and probably clip running LSi's.

You could also look at the Pioneer SC line. I've heard that setup on one of those receivers and those ICE amps drive the LSi bookshelves fine even tthough they're not rated down to 4 ohms. The Pioneer would sound much better than the Yamaha IMO.

The Yahama would be able to drive the LSi9s (on the test bench it did very admirably driving two 4 ohms loads), but I don't think it is a great idea to run more than two 4 ohms speakers off any avr. I would look for a cheaper avr that has the features you want without worrying about the power ratings (just make sure it has preamp outputs) and then get a nice used 5 channel amp.

Keep your nad if your happy with it, Buy a Blueray with analog outs ( oppo bdp 93 ). Analog out to your nad for sound. hdmi to your tv for picture.

I agree with this comment. Since your TV has 4 HDMI inputs, the suggestion to use the TV to do video switching and look into a blu-ray player with analog outputs is very valid. The bdp 93 will be less expensive than the Yamaha AVR, which will most likely be a step down in amplification from your current NAD. You will still be able to get Dolby TrueHD and DTS HD-Master Audio; the decoding will be provided by the player instead of the surround processor in the AVR. And you may avoid some headaches that seem almost inevitable with HDMI audio connnections.

For context, I run a similar 5.1 setup as you: LSi9s in front with an LSiC. My surrounds are older Polk speakers, but I will be installing the vanishing series in ceiling speakers soon. I have an OPPO BDP 83 and a 62inch Toshiba DLP TV. I recently upgraded my AVR from a Denon AVR 3802 to a NAD T775. In terms of ability to drive the LSi speakers the NAD is much better than the Denon ever was, but I've been very frustrated with my experience running audio over HDMI connections. The HDMI issues all seem to be related to handshake problems. I'm sure that some of these are due to the way the NAD has implemented their support for HDMI, but I've also seen and heard reports of similar issues with other companies too. I am working with NAD on this, and they are very helpful, but I really believe that HDMI (really HDCP) adds too much complexity to the environment. On the other hand, from the analog outputs the BDP 83 is fantastic.

BTW - nice TV!
