Thanks, I just ordered an XPR-2 and XPR-5 after I receive them and get them hooked up to my B&W 803D's and Matrix I will post my thoughts.

@jevans64....koooool....that helps me alot...my brother-in-law is an electrician...Il get him over to my house asap..lol....to wire me up sum 20 amp........What kind of speakers do u have for ur mains ???


Forgot about this thread.

Powered by Emotiva XPR-5
Front L/R = Definitive Technology BP7000SC
Center = Definitive Technology CLR 3000
Surround L/R = JBL L7 ( used to be main )

Powered by Denon AVR-5308ci
Surround Back L/R = Definitive Technology UIW BPZ/A
Front Height L/R = Definitive Technology SM55
Rear Height L/R ( Surround B ) = EoSone RSR-350




duc135 makes some valid points about running a sub-panel. I wanted to run a sub-panel but didn't really have a good place for one that wouldn't require long runs from sub-panel to where my receptacles would be. I actually ran five 20 amp circuits. One was for my lighting ( 13 x 60w PAR16 cans. ) Probably overkill for just lights, but I really needed to get the lights off of the circuit they were on. The original wiring was/is a cluster-**** with several rooms on the same circuit. I dedicated four 20 amp to the A/V part. All the wiring was less than 160-170 feet anyway. Using a sub-panel, I would have had to run 40' of 1 or 2 AWG to a closet and then 25' 10/2 AWG each to the A/V room. I have a 200 amp breaker panel but my usage load is way below that.
jevans64, where did you get that TV stand? What is the name/model? I am having a tough time finding a TV stand DEEP enough to hold an XPR-2. Thanks.

The TV stand is the stock Mitsubishi stand made to match their 65" DLP TV sets. Can't tell from the photo but both the XPR-5 and Denon AVR stick out about 2 inches because I wanted a little room in the back for the banana plugs and interconnects. The stand is a standard 20" deep. The top is slotted so that the Mitsubishi DLP fits into the slot and makes the TV look like it is flush with the rest of the stand. I liked the stand so much that I modified it with a router and 1/4" wood chisel so that my 73" Mitsubishi DLP can fit into the slot. The stand for the 73" TV looked like it wasn't as sturdy as the 65" stand. I don't care about the few inches of overhang that is present now with the 73" set. Model number is MB-65G but I bet they will be extremely hard to find new these days. I paid $300 for it when I bought the 65" TV. I think they were made by Bush Industries, so they might have something similar without the " pocket " for the TV.

Jim, are these three pairs hooked up or just there for the show? If you are using parallel set up (meaning more than one speaker the same channel), how did you handle amplification? Which amp powers which speaker?
I am using a parallel set up as well, but it is only for two pairs, not three. Thanks.

My XPR-2 arrived today. That thing runs pretty hot, while the XPA-5 is cool as a cucumber. Why ? Bias settings? What does that mean sound-wise?

While I cannot say without knowing more about the design, I would say yes, bias settings. Higher bias in the output stages means more class A operation and potentially less distortion around the center crossings of the signal. In practice there may be little if any audible benefit but some claim higher bias means better sound. Feedback handles the distortion issue so higher bias probably does not provide much in the way of audible benefit and just adds noise. However, there is the potential for greater stability into lower-impedance loads with higher bias. There are so many trades it is hard to say the benefit (or lack) in this case. There may also be greater power in the driving stages given the need for greater voltage swing to produce higher power, and that higher voltage also means more bias power even if the bias current is the same as in the lower power amp.

I wouldn't worry about it.

Keep it cool and enjoy the new amp!

I have XPR 2 running the 3 pair's in parallel (easily accomplished with xss1)and the XPR 5 is powering my center,surround ,and surround back

The XPR 2 is a completely different animal than the xpas if you go into An XPR 5 YOU WILL SEE THAT IT RUNS HOTTER THAN THE 2...BUT NOT BY MUCH

Thanks for the reply. I dont understand. Your XPR-2 is connected in parallel to three front pairs of speakers? One stereo amp is powering six speakers? XSS1 is an EMotiva speaker cable, right? Or am I missing something?

Yes that is correct..I have an xss tieing the 3 speakers together then a transparent to the amp on each front channel... I have a 2.3 ohm load being seen by each channel and the amp loves the load it sings like im at a concert in the front row.

The result of what I have done is to allow the amp to run wide open and my sound stage seems 5xs bigger.
It's a major improvement for music listening.

Thought the amp was 4ohm rated only?

MAn, you are done now. The never ending upgrade cycle is there for you. First 10K, then 50K, then 100K then 500K.

Let me know if they sound Cleaner to you once you have the EMOTIVA. The larger crowd is on the side on NOT needing ANY extra Amplification but the AMP Crowd BEATS you WITH their FLowery JArgon, some of which does not even make sense. They are counting on the novice to be so impressed by this Techno-Jargon that they think they will find the ideal sound if they use an External Amp. Also the feeling of owning something that you feel automatically makes you an Audiophile hehehehe.

Been there done that, thank god I did not buy anything.

You Ears should AND your Speakers in that ORDER if you crank them up too loud and it may not be CLEAN.

You should really have waited for that HT friend of yours to come and give you some advice on the Room Nulls and Sound Treatments and THEN would be time to buy the AMP.

Congratulations though for having the discretionary income to throw caution to the Winds. Please do share if you percieve that there is a noticeable difference in your sound. At least then it would be worth it.

There is a Rabid EMO following here but they are only at the Lower End of the so called Audiophile Ladder/Scale. Should have gone for the ATI or Carver or one of those Higher end ones to REALLY get the CLEAN sound. EMO vs the High End is like the Pro Amp vs the EMO debate LOL.

There was some great great advice from the people here. Great Thread.

I thought they are 4ohm stable, not 2. You are most likely getting 1.33ohm average. That is pretty low. But if it sounds good to you that all that matters. I am using parallel fronts as well (Maggies and Polks), but different power amps handle them.
Thanks for the answer.

From Emotiva:

Quote:
"Minimum Recommended Load Impedance (each channel): 4 Ohms (which equals one 4 Ohm load or two paralleled 8 Ohm loads per channel)."
I guess if you push them hard and for a long period you make kill your amp sooner than you think. Just trying to help, dont shoot me!

I agree I just read the same thing from their website and kind of curious where you seen where they actually are stable to 2 ohms

In the manual that came with the amp it says it can drive down to 1 ohm and is 2 ohm stable...it's there XPR 2 only that says that in the manual

I am sorry, Jim, I just read the manual and it doesnt mention 1 or 2ohm anywhere. Only 4 and 8. Please keep in mind the only reason I am saying this is that your XPR is a great amp (well, nowhere close to the Krell Evolution, but great bang for the buck!) and should be treated as Emotiva says in that very manual:

Quote:
Always install your XPR-2 according to the manufacturer’s instructions and only use attachments or
accessories specified by the manufacturer.
The only mention that MAY be misinterpreted is this:

Quote:
Totally stable - with virtually all real-world speaker loads.
But this means any PAIR, a single PAIR of speakers, not three pairs.

Thank you.

Plus, these 3 pairs are worth one respectable B&W 801 or 802 pair (at least a used pair). That would make the setup sound much better! Better than 12 pairs of these.

LOL sure. Read up on phase cancellation.

If you want multi-speaker sound from CD, then use a DSP ie Logic 7 Music. Not just bunging in same signal to multiple speakers

If you need to 3 pairs of speakers to produce a big good sound, buy better speakers.

First of all the impedance is 2.667 Ohms and I got these for a song..so if either the amp or the speaker's blow I'm still ahead of the game because I got the amp and all the speakers for less than 1 804
