Emotiva XPR-5 - Page 4

post #91 of 218
How long does it typically take for the custom middle atlantic faceplates to show up the database? I see them there for the xpa-5 but no xpr-5 yet.

A serious beast! Talk about making your local ELECTRIC COMPANY richer. Have fun to those who do purchase. Later!

Add me to the list of XPR-5 owners, mine arrived on Halloween and I was happy to see the box was in very good condition. It only took 2 days to ship from Franklin TN to my house.

After the hauling the box upstairs and checking to make sure the amp powered on I ended up rearranging a lot of gear in my home theater. I was upgrading and simplifying at the same time, my previous configuration used 5 separate Audiosource amps which served me well for the past 3 years. I'm only using 4 channels right now because I am waiting on a custom build center speaker that isn't finished yet.

I have to buy longer speaker cable now for one of my rears but after that is resolved I will re-run Audyssey and see how it performs sonically. The meters are a nice touch and lots of dimming options.

im planning to build a home theater. if i'll get the XPR-5 please help me what speakers for my main fronts to get. polk audio RTI12 or polk audio LSI25? thank you.

these are outdated speakers from polk but are still available at ebay for a cheap price.

If you are planning to use these speakers for home theater purposes, then you will have to pick the RTi 12 (RT = Reference Theater). Or perhaps, you might want to look at the current series of that speaker - RTi A9.

Look at my gallery, I do have the A9's on cherry.
post #96 of 218
thanks for the info. The RTI12 is cheaper on ebay too compared to the LSI25.
post #97 of 218
The Polk LSi series speakers are a whole different league of speakers, compared to the RTi line. I've owned both in the past and the LSi's are GREAT for HT, let alone music. RTi's were good for HT, but way too harsh for music to my ears. The LSi's are built better as well and use better quality drivers, to include a very good Vifa tweeter to boot. If I had to choose speakers, I'd get the LSi series any day of the week of the RTi's, IMHO.

Btw- sorry to derail the amp thread, but had to comment on the Polk's:)

XPR-5 says 600watts into 4 ohms i am running the MK Sound package

http://www.mksoundsystem.com/home-products/150-series/

The s150 L/C/R RMS 180w 4ohms
The S150 T Rears RMS 100w 4ohms

recommend power rating for speakers are 25 - 400 Watts for front and rears 25 - 200 Watts

would i do damage with this amp
post #99 of 218
Only if you turn the volume up to eleven.

But you know the XPA-5 will do the job just as good. It's specced at 300 Wrms @ 4ohms.
post #100 of 218
XPR-5 how does it compare to a Parasound 51 in quality and sound?? just using it for home theater purpose
post #101 of 218

post #102 of 218
I've never heard Parasound amps but I have the XPR-5 which I tried with my Jamo R909 (stereo). These can take peaks up to 800 watts @ 4ohms and play clean up to concert levels. The XPR-5 doesn't even sweat. With Dubstep, I was able to give the leds a workout, but still the XPR-5 wasn't choking one bit.

IMO, amps can be judged by their specs to a great extend. Never mind the Watts though. Take a look at the power supply and the secondary capacitance (SC: this tells you how fast the amp will respond).

XPR-5
PS: 3,300 VA
SC: 180,000 microfarad

Parasound A51
PS: 2,200 VA
SC: 164,000 microfarad

So both amps are very, very strong. Parasound makes fine devices, but at a cost I am not able / prepared to pay. The XPR-series have what the rest of the Emotiva range lacks: a touch of luxury in looks and feel. (my normal amps for the Jamo's are the XPA-1)

Erwin,

After using them for a while, which do you prefer the XPA-1 or the XPR-5?

That's a very cruel question! I love both my children...wink.gif

They're in different sets ofcourse. I always thought the B&W CMC centre speaker was the weak link in my 5.1. But it seems all it needed (being a mediocre 87 dB/Watt efficient) was a powerful amp. Enter the XPR-5! But probably a XPA-5 would have caused a similar improvement. With the XPR-5, the LED's from the center channel are usually the only ones moving. But with Red Tails (Blu-ray), they all moved, and they moved a lot. This set is now transformed (with a UMC-1, coming from a Yamaha RX-V2700). Especially male voices are now sounding like men, not boys!

But this doesn't tell you which I prefer. Let me put it this way: I will never replace the XPA-1 powering the Jamo R909's. But if a thief (oké, two thieves biggrin.gif) stole my amps, I'd probably get a XPR-2. It looks cool and takes up less space. The XPA's are more modest looking. I will probably even remove the trims and insert little screws that don't stick out for that extra stealth look.

Just the opposite, they had been there, but disappeared almost completely from the higher quality system but the lower categories.

I tried a D-Sonic 400 W/C amp a few years ago with my Revel Salons (87 DB at 1 watt).
I liked the speed but the high end was rolled off. This is not always bad.

The Revels dip to 3.8 ohms and are difficult to drive.
The D-Sonic had weak bass, it simply could not drive my Revels.

I sent it back. It was also suffered cosmetic damage and dealing with Dennis was a PIA.
D-Sonic could sell the most perfect amp in the world and I would not buy it from them.

I have a Sunfire 7400 and this is a very nice amp.
I have auditioned an older Outlaw 200 watt amp and I was surprised on how good it sounded.
Recently, I installed my friends Oppo BDP-105 connected to two outlaw mono-blocks.
What struck me as the speed and dynamics.

It got me wondering if the Sunfire is powerful but not fast.

At this point I would not want to spend much over 2K on an amp.
I am not sure these amps would be an upgrade but I considering an XPR-5 or a Outlaw 7700.

Outlaw publishes slew-rate where Emotiva does not. I get feeling it is the speed I liked about the Outlaw.

So on the short list is an Outlaw 7700 (possibly bi-amping my Revels) and the XPR-5.
There have been no profession reviews of the XPR-5.

Any advice from folks with these amps?

- Rich

P.S. Bi-Amping makes sense because:
1) You get more power
2) If you are pushing out a ton of bass, that amp may be clipping but the amp driving the mid/tweeters will be unaffected.

P.P.S. The Parasound is out for budgetary reasons and because it is Silver which fails the WAF.

1. No you don't.
2. Not unless the mid/tweeter amp is capable of higher voltage swing (IOW, is capable of more watts per channel) than the amp you're using for the low end.

The low end draws more power / current. When amps clip they generate high frequencies. That in the case of bi-amp go nowhere.
The upper amp will not be getting stressed no matter how loud you play. Even power sag would not likely affect the upper amp.

The Revels are 4 way speakers with upper midrange and highs on one end and mid-bass and 3 woofers on the low end.

Sorry, it's not quite that simple. I wish it were though, and I understand if you don't believe it. It usually takes a while to get it sorted and come to grips with it.

OK fine, whoever you are, you clearly know best.

Passive bi-amping implemented in AVRs offers no increase in voltage headroom, thus both amps will generally clip. If you add a line-level crossover before the amplifiers you can gain headroom.

Consider that each speaker is effectively two speakers.
Got an extra amp channel and massive reserves of a dedicated amp and there can be a benefit.

Since this is the XPR-5 amp thread which bears no resemblance to an AVR where a single channel can exhaust the available power supply, I believe this is not applicable.

None of that matters in this regard. You can protest all you want but it doesn't change the facts.

Um, not true. Depends on the receiver, NAD specfically allows for this in the T775/7 and T785/7 HTR's, and it makes for beter sound. If you can bi-amp using seperate amplifiers (or channels) do so. Consulte your manual.
post #115 of 218
Might it change the sound...maybe, and you'll certainly screw it up if you use amps having different gains. But more power, more headroom? Nope.

Sure, but "can be" is the operative phrase. There is often no benefit, at least IME.

If an AVR drives the amp without a true line-level crossover then I believe my comment is relevant as both amplifier channels will be producing the same output voltage.

Do you really think 400 Watt x 5 (500 Watts 2ch drivven, how's that for your fronts) would not be plenty? No, really? wink.gif

XPR-5 gets my vote... Looks better than the black box 7700 too.

OK, and I think some Onkyo's include a line-level crossover as well. I should have qualified by saying "most AVRs".

Might be an interesting post for an AVR thead.

However, there is no way on gods green earth the tweeter and midranges draw the same power from the amplifier.
Amplifiers are not pumps pushing the same wattage no matter what is on the other end.

Right. No need with an XPR-5 but the 7700 maybe.
