Hello, This is one of my first posts on the board. I currently own a Denon 3312 receiver and a pair of Polk audio Lsi9 Speakers. I am impressed with the sound they are producing but i feel that there is much more to be had out of them by using an external amplifier. I am hoping to achieve tighter lows and fuller mid range frequencies by using an external amp. I've been trying to hunt for a Rotel rb 1070 or 1080 also looking at Nad 2600a, 270 or 272. Hoping to hear fellow forum members opinions. Room is 23'W x 16'D x 8'H listening distance is 10' . 50/50 Music/Movies. Thanks for taking the time to read this post. smile.gif

PS: The Denon 3312 is very new to me. I have the Audssey Eq turned off due to the fact that its nice to adjust treble and bass settings and Audssey Eq didnt make a difference for SQ, If I am doing something wrong please let me know.

Yup .. you're likely doing something wrong. Are you using a camera tripod or mic boom stand to support the mic as suggested in your Owner's manual? Suggest you read through the Audyssey FAQ/101 Guide linked in my sig. Also, unless you currently have the AVR volume maxed out near distortion levels, you're not likely to gain any benefit from an external amp.

Also note there is a dedicated thread for Denon AVR-XX12 owners linked in my sig. Review posts 3-6 in that thread for more info regarding your AVR.

I don't think you're doing anything wrong. Audessy seems better suited to surround systems. I would leave it off for stereo use.

I also think you're correct in that you may be missing something. The Lsi9s are 4 ohms and probably a tough load for the 3312. If you're going to stay with a stereo setup you don't need all the extra "features" you're paying for by getting an AVR.

Maybe sell it and get a nice stereo pre/pro and amp instead.

Thanks for the replies. I understand the that i do not necessarily need all the features of the reveiver for stereo use. I am planning on purchasing a center channel (LsiC matching) and a Hsu Research VTF-3 Mk4 in the next coming months. Maybe I would be better off buying the woofer now to fill out the lower frequency's. I am a bit torn to say the least. I really am not purchasing the amp to drive the speakers louder I just want a more refined and fuller sound from them.

Right. No reason to believe it will provide any benefit over the AVR's amps.

I am curious to hear some replies in regards to the Bi-Amp feature of the 3312. I'm aware it doesn't seem to help when the receiver is already powering 5 speakers but curious if it would help in the mean time with my 2 channel set up... the lsi9 speakers are 4ohms and the sensitivity is 88dB.

Won't help in any configuration. Just a marketing ploy.

Then don't spend any more money on another amp. It won't sound any different.

The best subwoofer I know of, for under $1000, is the NHT B12D, for $700. it is excellent.

If that is over your budget, then I suggest the Klipsch RW12D, which Amazon has for around $400. If you want good sound, don't cheap out on a subwoofer! Cheap underpowered subwoofers are pretty crappy-sounding.

One amplifier that would quite possibly improve your sound quality is the Marantz MM7025, which runs around $800.

4 ohms would be a problem if you were driving 5 speakers with that impedance, but your receiver should have no trouble driving 2 or 3 of them.
