A PAIR of these draw less than 1 watt just sitting....Leave 'em on if the auto on is disturbing. 1 watt? I'll bet its not even THAT. You will never see it on your electric bill and in winter you'll never see the extra heat kicked out as a reduction! You seem to have changed your tune. Actually they idle at 5.6 Watts, so 2 of them about 11W, I have 6 of them so 33W. When is it ok for me to care? specs don't call out the on/ no signal number, just the power needed to 'sense' or maybe call it 'housekeeping'. I think I'm consistent. While I'm not PERSONALLY a fan of 'D', having owned a pair of ASP amps for several years, I DO recognize the power saving aspects of the topology coupled with a SMPS. I'm ALSO not a fan of Switchers, regulated or not. For several reasons which I'll omit from this post. I wouldn't worry ever, unless you were in California where Electric Bills are huge. I'd have to look up numbers, but last month I used about 250KwH for the month. Not much by the rest of the countries standards but my bill is near 100$, even with discount....That includes GAS. A 'D' amp with Linear PS might be a slightly different deal. HYPEX used to sell linear PS components, but it's really not hard to DIY, even using 'cookbook' techniques. |

My Kill-A-Watt meter informs me that each of my PA-1 amplifiers uses 6 watts at idle with no signal.

I have my four PA-1's powering my front & rear height channels, and they turn-on mainly during the scenes where the Dolby Atmos/DTS:X tracks are most dynamic. They also immediately come on when I'm playing a CD and using the Dolby Surround Upmixer. Interesting that you two find the sensitivity too low. I’m also now using them for heights, when I first tried them a couple years ago and they didn’t come on, I bought the triggered outlet. It’s possible they might work now, but at this point I like that they just trigger on and off with the rest of the system. I’d trade the auto feature for some trigger inputs though, or maybe a user adjustable sensitivity control. I'm with you on the trigger inputs, but so far the "Auto On" feature has worked for me. |

I've been looking at these PA-1's and would appreciate input from Lounge members.
Right now I am using Crown XLS-1500 class D amps for HT, connected to my XMC-1. They work fine and I've never had any problems with them. Sound-wise, they seem fine as well for HT but fall short when compared to my VTA-120/SP-14 combo for music. I've no plans for replacing the tube preamp/amp because I'm really happy with those.
The only negative about the Crown amps is the faint hiss I can hear through both the tweeter and woofer (different frequencies, obviously). With my ear a foot away it isn't audible. That hiss is inherent in the amps because it is the same whether the XMC-1 is on or not, and it's not dependent on turning up the volume. The hiss doesn't interfere with the sound when playing a movie or TV show and it sounds fine.
So my question is whether switching these out for PA-1's? There is one Crown amp in bridged mono mode for the L,C and R speakers, and one amp in stereo mode for the two rear speakers. If replaced, it would be with three PA-1's across the front and maybe a BAS-X A-150 for the rears.
Any thoughts?

But if I recall that for the most part you don't notice much difference in amps. So because of that, I would advice you to save your money and stick with what works.  |

I can definitely tell the diff between the tubes I use for music versus the Crowns, but not so much between SS amps. I probably wouldn't hear much if any difference getting the PA-1's, especially with it being for movies and TV, but I was thinking it might be nice just to get something different. Must be getting restless with all this lockdown stuff going on.  |

I am considering ordering a couple of these but I notice there is no way to choose a face plate color, are they still available in all black or only black with aluminum border?

They've always been the same, black plastic faceplate and black aluminum frame. Isn't this one black? Or is it just the angle of the light on the front? My bad if this is the case (LOL).  |

Also: 1) How do we know if they are any better than the PA-1's? 2) They don't have balanced inputs to match my XMC-2. 3) If I want three HQ channels to drive my LCR then this doesn't suit. |

Was simply providing a potential option. Both are ICE based amps, so it would probably be safe to assume similar performance. If you purchase 2 XTZ amps, you can use the second in "mono" mode to biamp the center. If XLRs are needed, then the XTZ isn't for you. |

I don’t understand what you mean by “all black”? Yes, as I said, they have always been “all black” and that’s your only choice, there are no sliver options. |
