Hi All, We're really pleased with Audioholic's review of the UPA-7. It is a great amp. Regarding crosstalk: The levels he is measuring are well within reasonable limits and are in fact better then many other multi-channel amplifiers. They are not problematic in any way and you will not hear crosstalk as an an artifact or a by product of operation, so do not worry about this. Enjoy one of the greatest amplifier bargins on the market today!  Cheers, Big Dan I fully agree with you Big Dan. |

Been trying to get on their website all day to read the review but with no luck. I get the opening titles and then it stops. I think their server needs upgrading. Not only their servers...  ;D |

Congratulations Emo but I wouldn`t of expected anything less from an Emo amp I consider my IPS-1 amp the crowning jewel of my system

I liked the review, but then I general like all Gene's reviews. He avoids ill defined terms in his reviews. I believe he honestly tries to stick to the facts.
It would have been interesting to see a movie in his listening tests. Just to see if he could hit reference level with the amp in his setup.
I also would have liked to see a continuous all channels driven test. By continuous I mean like 5 mins. It's not that important, because you don't need full power continuously. Your average power draw is likely low, perhaps less than one watt. Peaks are where you need a lot of power, and it seems feasible based on the tests that you may have more than 125 watts / channel on tap when needed (and for movies, all channels are likely not all peaking at the same time.)
For the price, it's very hard to beat. If you want out and bought 4 cheap pro amps (I won't mention names, but there's a popular pro amp for less than $200 with about 180 watts / ch,) you are looking at $800. The pro amp I am not mentioning would give you more power, but the actual peak SPL levels would not be much more. It's also a lot of amps to rack and power, etc.
As for whether you can live with the UPA-7 over say some combo with XPA amps, just remember the law of diminishing amp returns...the peak unclipped SPL from an XPA vs a UPA is likely less than 3 dB. You can save money by making do with a little less SPL.
People who want to play their music as loud as possible with the cash would of course go the XPA route. People who watch primarily movies and don't have a "reference" level obsession will almost certainly live happily with UPA power.
All my own opinion, of course.

Most of us here know exactly which amp(s) you're talking about. But why do you seem afraid of mentioning it?  ...Because the people here at the Lounge don't have any problem with that whatsoever. Behringer Pro amps? ...Yamaha also has some great Pro amps at great prices. And you can get some powerful amps for real cheap at Audiogon. * But the UPA-7 still remains a true leader among them all. ...And from a Value & Performance standpoint, bar none! |

Using 5 channels for a 5.1 setup and the other 2 for a zone 2, 2 channel setup, I found the crosstalk to be a big issue. Its actually very audible if your trying to use the amp for 2 seperate zones. When Im trying to use a pair of speakers(5ohm rating/88db sensitivity) in the 2nd zone at a reasonable volume level, the other 5(8ohm/89db sensitivity)channels even though they were "off" were singing away loud enough to wake someone from a sound sleep. |

I agree with everthing he said....except I don't HEAR any crosstalk. I know ntrain has complained about it but......my ears ain't as good as his. ;D Try using a UPA-7 for 2 zone operation. You probably dont hear crosstalk when your watching 5 or 7.1 movies or music because the volume output from whatever speakers are in use will mask any crosstalk. Its there, and its bad enough were I would never use or recommend a UPA-7 for multizone use. |

What happens when you unplug zone 2 from your reciever and plug something with its own volume control like an iPod? |

Well, I for one, think it is a big improvement over the previous avatar! ;D PS: After looking at that avatar for 10 seconds or so, I think Ntrain could use a downer or two!  |

What happens when you unplug zone 2 from your reciever and plug something with its own volume control like an iPod? The receiver being used is/was a UMC-1 which was ruled out. Same with using a couple different Adcom CD players with their own variable output swapped in instead of using the UMC-1's own analog switcher. I could have just one pair of RCA's connected to the UPA-7 but all channels would play if all the speaker leads were connected. The crosstalk will also increase and decrease depending on the volume set as well. The fact that the zone 2 speakers were lower impedance/sensitivity magnepan speakers made the crosstalk issue even worse. I went into full detail on my UPA-7 review in this same review section. |

a couple of month's back I was reading their forums, I would say any cred that site once had was sh** to sh**, I think the review is a token piece offering to quell the bullshit on their forums..
Personally I think the review is great scoring browney points, though a little late in reviewing emo gear...
I think someone gave him the amp to shut his mouth to prove a point..
Personally I take anything audioholics review with a grain of salt..
the upa-7 is a great cost price for the power you get, though you could many a route with the xpa series in a 7 channel configuration..
personally as great as upa-7 is the lack of xlr inputs stops me buying it, I would spend for medium budget upa-1 x7 for 7 channel price no limit 7x xpa-1's for seven channel use..
if looking at 11 channel 11x upa-1's, 1x upa-1 2x xpa-5's or 1x xpa-1's.. pointless adding in xpr line in sinne not available yet
my opinion on xlr inputs, whether you have a upa-7 right through to a xpr-1 xlr inputs should be standard on all product lines..
