RTi10's with AVR5700

Hello!
First time poster, not first time reader though.
I just took a Denon AVR5700 and a pair of RTi10's from a pawn shop for a total of 550, can I get arrested for that?!?!
Everything is in great working order. Channels work, clean and pristine etc. I have not had any experience in HT before, just a lover of stereo listening.

The Denon does not have A & B front mains. It does, however, feature a 5 channel stereo mode using the A surrounds with the mains and the center. Question; will I kill the speakers or the reciever using the 5 channel stereo mode to Bi-Amp the RTi's???? I have had them hooked up only with the front channel and am looking for more power as these things (as stated by users in the forum!) are power hungry.
I do not want to kill the AVR or the RTi's because I know I got a great deal and want to get the best sound possible from this 2-ch setup.

ps: I am planning on accquiring surrounds and sub at a later date. Thanks for any assistance!
pps: Should I look into another amp to properly bi-amp these RTi10's?

    I think the biggest issue is that regardless of whether or not you bi-amp with the receiver, the receiver can only put out so much wattage. I don't think it will put out more power simply because you have more channels connected.

    The consensus on here seems that its best to have a separate amp for the RTi10s. I'm picking up a pair this weekend and I plan to buy a separate amp in the near future. My plan is to connect the highs to my harman kardon receiver and connect the lows to the amp, although some have suggested that the best sound will be obtained by using the amp alone. I'm looking forward to experimenting with this!

    I guess the next logical question is as follows: How much to pay for a good amp!?!?!

    My experiment with the AVR, it is 5x140w, and biamping seems to be going well. Lows seem stronger and more active. I realize this is dumb to do, but until I gain possession of an amp this will have to suffice (as long as it is not detremental).
    Any other inputs?
    Thanks in advance!

    hey, 140 wpc is pretty sweet! I was looking at a used Emotiva LPA-1 ($450) or a new Emotiva UPA-7 ($650). They each put out between 125 and 180 wpc depending on how many speakers you have connected. I imagine using that in conjunction with your AVR to bi-amp the speakers would be awesome! you would have a minimum of 265 wpc channel available per speaker which is phenomenal.

    How many channels does the Emotiva offer?
    I'll probably have to research amps more later on this week, but that does not sound like a bad idea. I like to hunt for good deals and finding a nice used amp would be fun! I will be keeping in touch with this forum and the more experienced AV users. Thanks for your help.

    No prob.

    Both the LPA-1 and UPA-7 are 7 channel amps. Emotiva makes amps with fewer channels but they don't cost any less. I cant wait to get my hands on one!

    I have an LPA-1 driving RTi10s (the emotiva amps and RTi10s seem to be a hot topic - I've posted this same response several times). The LPA-1 cleanly drives the RTi10s to ear-bleeding levels in my large room (30ftx12ftx10ft) with bass that will send the neighbors running to knock on my door. You won't need to bi-amp RTi10s if you are using an LPA-1 or UPA-7. I've tried higher wattage amps and only found diminishing returns (if any). Also bi-amping with two different amps (ie a receiver and an external amp) isn't a good idea as the gain structure between the amps is different.

    Would the differing gain structure fry the crossovers??
    I have not looked into the Emotiva, but it sounds like a great idea. Just driving the RTi10's with the Denon is not enough for me. The sound is hollow and less rich than I think the RTi's can deliver.
    Question: I don't know if anyone here is familiar with Denon AVR5700's, but the D has a 'direct' feature in stereo mode which supposedly bypasses the processors(?) in the amp.
    Uhh... what does that mean and why does the 'direct' feature have more volume capabilities (say -30 when in direct is equal to -12 in other surround modes) than in others. Just curious as I am new to the nicer-listening-to-music-with-better-equipment game.

    Most avr manufacturers have something similar that allow for a more 'traditional' 2-channel listening mode for 2-channel source material (LP, CD, etc).

    When in 'direct mode' (Yamaha calls it "pure direct") the signal path for the audio bypasses most/all of the DSP circuitry which some listeners prefer with the mindset that the less you muck with the bits the better the sound.

    I actually prefer using the "pure direct" mode myself for LPs, CDs, etc. ;)

    I would guess that you are getting more gain in direct mode because the Denon's powersupply is not being asked to drive the outputs to the other speakers.

    fwiw,

    H9: If you don't trust what you are hearing, then maybe you need to be less invested in a hobby which all the pleasure comes from listening to music.

    Hey, thanks for the inputs, just got my hands on a Carver TFM-35 amp that will be powering my RTi10's...
    Will the Carver pound the RTi's into submission or did I waste my money? The Denon AVR 5700 was not cutting the mustard and the crap biwiring rig job I had previously was scaring me. Not too concerned about surround yet as you can tell, but maybe the surrounds could be powered by the Denon and keep the Carver powering the RTi's????
    Still experimenting, can't wait to get the Carver.

    I had the same problems with my RTi10's using a 6 x 75wpc Yamaha HT receiver and found two-channel hi-fi was very disappointing! I purchased a 20 year old Accuphase E-205 amplifier which puts out a minimium 80wpc, which would be very conservative. I found the RTi10's were completely transformed and the bass was astounding. I did find the RTi10's still restricted in the mid-range and they are still quite bright in the top end. I'm hoping with the Accuphase amp the RTi10's will continue to 'burn in' and hopefully open up in the mid-range. I can confirm the RTi10's do need some grunt to make them perform in two channel hi-fi. Apart from that they are a very good HT speaker.
