Just ordered an XR55 to power some DIY's I am going to build with a nom of just less than 5ohms but probably considered a 6 ohm design.


Looking forward to seeing if it is all that some claim. Design isn't inherently bright, so I think it will be good.


Was considering HTR5860 or RX-v657(?) but....$$$$$ and you guys(pro pan) can be pretty convincing


Looking forwar to seeing what it is like to have the PAN.

Based on the dipping to 5 ohm alone- you should feel free to exercise your 30 day return policy. Sorry to say.

Well, our first pesimist. Negative nanny, just trying to rain on ones parade?


OR justified. Did I just screw the pooch?

I dont think so. I run 4 ohm floorstanders just fine with these things, and I watch quite a few movies.


Besides, according to stereophile they maintain 93 percent of the current in 4 ohms compared to 8 ohms (about 169W/channel in 4ohms vs 91W/channel in 8), and I keep my receiver on about 12 hours a day. I think you'll be fine.

Thanks, that is good to know. Pretty happy with it?


Do you have a link to that article? I will try to find it.

sYKone, I just pulled the trigger on an XR55 too based on the reviews here. Either it's a great unit or Panasonic's got some savvy marketing people working this forum. I figure it's worth $230 bucks to find out which it is. ;-)

Congrats! My sentiments exactly. My only reservation is whether it will work as a preamp later, if I decide to expand and no HDMI. Let me know how you like the receiver, recliner and I will do the same.

no it will not work as a preamp - there are no pre-outs other than the LFE.

SiriuslyCold, that is what I thought. But i saw something about people using electronic crossovers with them or something. Maybe that was something else.

I'd love to see that stereophile article myself, please provide a link. Didn't know they ever reviewed the Panny...

newform research was (is?) using the Behringer DCX2496 as a xover but its placed before the amp, I think and the resulting signals went into the 6-ch analog input


you can read more at newform research

Thanks SiriuslyCold, I did some more research and you were right. Basically using the pan's as amps.

Okay. Have had it a couple of days and can't say much but that it runs the crappy speakers I have better than the crap I was using. Not saying much. It does look cheap though. Maybe I would have been happier with black. It may get customized in the not so distant future.


man, I need to get my speakers built.

Thanks!


Any way you could run the German review through some translation software? :D

I'm sure some kind German AVS member can do a better job at summarizing the review - but here's Babelfish's take:


The layman is astonished: "which is to produce, with its specially-flat plastic face and only 4.6 kilograms lebendgewicht the 400-Euro-Panasonic summa summarum more than 700 Watts?"


And the specialist is surprised: Why did Panasonic engineers, only because they enriched the predecessor SA XR 50 (7/04) around an output amplifier (together with tidy clamps for all boxes), insert a complete second six-channel equal digital Amp processor named TAS 5076 (details on page 20)?


That the SA XR 55, which snaps clocking digital signals not only with 96 kilohertz, but also twice as without any similar intermediate stage process directly can does not squint after twelve channels. It goennte itself the large IC doubling rather, in order to increase the connection flexibility. Speak, it is able, while it lets the two processors march accurately in the equal step, to synchronize ever two amplifier courses so exactly the fact that it it - while otherwise dangerous balance stream threaten - to join in parallel can.


Distorted to absolutely welcome but from sound-conscious: In the case of 5.1 rendition assigns the baking amplifiers to the SA XR 55 fully automatic the front Amps as support. With stereo it permits besides via b-Boxenklemmen Bi-Wiring. Then two output stages Bassund third the elevator chassis preparatory work.


The parallel operation promotes now completely crucially the current power. Not necessarily over longer phases, there the power pack well-being limits however with short violent impulses, which the SA XR 55 undoubtedly more energetically than its predecessor can pull through.


During the two or five-channel rendition the Panasonic pleased completely atypical, nearly already highendigen fine design immediately not only with particularly full of seeds, fresh and alive tones, but also with one for 400-Euro-Multikanaler. Madly, like sensitively it voices, brilliantly, as it transferred flashing piano runs. And if some listeners wished still more bass abundance, Panasonic can parieren: More sound gibt's in this class with distance not.

Mine arrived this week too. It is the black model. I don't know if you would have been happier with it - it's pretty cheesy looking too. But I am going to keep it in a cabinet so looks aren't a big issue for me.


I am using it to run a set of 5 Mirage Omnisat Micros and a Velodyne VX-10 sub in our family room. I haven't had a chance to do much except hook it up and watch/listen to some music DVD's. So far I can't honestly say it sounds better than my 20 year-old 55 watt per channel Yamaha integrated amp. Maybe I was expecting too much. I'll keep making adjustments and let you know.
