I only have 1-1.5" above mine, open on both ends, but my XPA's only drive my Rears and Heights and I never get close to reference, so they're not really working that hard.

So I just joined the Emotiva club by buying a new XPA-5 during the Holiday sale. I just ordered a Marantz SR6010 to go with it for preparation for my new 4K TV that I haven't purchased yet.

I will be running a 5.1 system for the foreseeable future. The amp and AVR are running Paradigm Studio 60 mains, Studio 20 rears, Paradigm Center channel that I never remember the model number of.

I was just curious what pre-amp or AVR the rest of you are using with your XPA's?

Me, a Yamaha RX-A3040, but strictly as a Pre-Amp.

Sony ES-something in one system. In the main system was a Pioneer SC-27, replaced by an Emotiva XMC-1.

Noob question: Is there a way to turn amp from stand-by to on remotely, in other words not having to push the button by hand?

If you can't take advantage of the 12V trigger it has, maybe something like this?

Hi, and welcome.

What receiver/processor are you using? I'm betting it has a "trigger out". If so, it's easy - hook up a mono headphone cable between your XPA-5 and the processor/receiver and you should be all set.

One more question. I have a power supply that cuts off power when I turn off my receiver-its a Monster Power MDP800 Green Powercenter. Would it be ok to plug my amp into it - it would power off completely, not standby, when receiver is off?

Those of you that switched to balanced connections running XLR cables from your standard unbalanced connection, was there an appreciable difference in sound quality?

Hi All,

I am thinking about purchasing XpA-5 . I have polk Atia9 speakers on front which i would like to drive with this amp as they are very power hungry . Currently i am running them on Pioneer sc-1228.

Does anybody here have some experience on how the polk ATiA9 will run with xpa-5

Thanks in advance.

I'll cut/paste what i posted in the speaker forum on a similar question:

I recently purchased Rti A9's on a sale.
So i ended up with new front L&R speakers.
I then moved my energy 5.1's back a slot to surrounds, and moved my paradigm surrounds to backs.
All of these were powered by a Pioneer Elite VSX-33 with 110 watts a channel. i did have a powered sub though.

Sounded great, couldn't hear clipping in 5 channels or in my new 7 channels as loud as I could listen to. The amp was probably only putting out 40-50w a channel when I'm powering 7 channels, but it was still sounding great in a large room. I could not hear distortion or 'lack of power"

Sounded great, but i still had a wad of cash to burn. So i bought a emotive xpa-5 amp at 200 watts/channel, a new denon x6200w receiver, and 4 new ceiling speakers for atmos.

I now have 11 channels of speakers, and rti A9 'power hungry' speakers combined, but I'm not worried because I have a 5 channel external amp along with the receiver to power it. with 11 channels with only a receiver id be potentially worried because maybe then the power won't be enough to power all 11 channels without running out of headroom. Depends on volume then i guess.

Short story, i have not "heard" the benefit of an amp yet, because I have yet to hear clipping which is probably the only time you actually need to add an external amp. Maybe its my poor non professional ears, maybe its that I added an external when i went from 7 to 11 channels. Point is if you're not yet hearing clipping, if your current receiver is powering your speakers at a volume you listen to without clipping, an amp will not make them sound better or suddenly bring out new sounds. "power hungry " i guess means adding more power doesn't make them blow up, but adding more power doesn't make them sound different.

That said I'm looking for a new xpa-2 amp just so i never have too worry about head room in a speaker amp combination and it looks impressive !!!.

With the Denon X6200W there are only 9 built in amps. So to go from 9 channels to 11 channels, an external amp is needed. This will give the 7.1.4 Atmos speaker configuration layout.

You can use the XPA-5 to power the fronts, center and surrounds that will make up the bulk of a movie soundtrack. The remaining speakers (back surrounds and ceiling) can be powered by the internal amps of the X6200W.

The idea is to hit reference level of 105dB peak at the Main Listening Position (MLP). The Polk Rti A9 have decent efficiency of 90dB/W/m so it'll depend on how far way the listening position is from the speakers. Might want to check out the power requirements using this web app: http://myhometheater.homestead.com/splcalculator.html

Curious to know if 200W per channel of the XPA-5 can get you 105dB peak at the MLP in just stereo mode.

I've never noticed any difference in sound quality . That being said, all of my amps are connected to my pre amp processor with balanced XLR's. Before I made that switch years ago, I would have intermittent low level hums , buzzes or a hiss show up in my speakers. After the switch, those issues went away. That's the main advantage of balanced XLR connections...far less chance of picking up noise along the way from preamp to power amp.

Main system: Thiel 3.6 L/R speakers, Pair of Velodyne F1500r subs, B&W HTM center, Emotiva and Polk RTi 28 surrounds, Integra DHC 9.9 pre/proc, Pair of Emotiva XPA-1's, Emotiva XPA-5, Threshold SA/4e, pair of Threshold S/200's, Oracle Delphi TT w Magnepan Unitrac 1 arm and Shure V15 - Vmr, Logitech Squeezebox Touch, Oppo BDP 83 optical disc player, Threshold T2 preamp, Denon DR-M44HX cassette, Pioneer CLD-97 Laserdisc. LG PF1500 led projector,Elite 100"tab tension-ed motorized screen.
