Take an extra power cable you have laying around and break the ground pin off the male end and try that. Chad I can try that.....but, why would this one do it. My other 2 PA-1's are dead silent. It's clean power going into a CMX-6 power strip / conditioner thingy. Emo is already sending me the return label thing and after talking with 2 different tech support dudes they agree to send it back.....not one of them mentioned the destruction of a power cable??
I've heard some people have ground loop issues when using unbalanced connections, mine were all fine but I used XLR from my XMC-1 when I had them  Chad |

I have a question about this hum thing. I've heard about this sort of thing for decades and ONE person I read about had a solution.
You power coming in has 3 wires.....Hot, Ground and Neutral. Is it possible at the AMP end (internal) that Hot and Neutral were reversed? Is that even possible?
What would happen if you swapped hot and neutral on a power cord? Disaster / smoke / flames OR would that take care of the hum?
DO NOT DO THIS Unless you know in advance. I hope someone like an electrician or good tech will chime in with an answer.....??

Just received my first PA-1 for playing with. I really like the look an feel of it, its a nice bit of kit, and the packaging is awesome!
I plugged it in to my Dynaudio centre speaker. First impression, very bright and almost brash in the mid - high trebles, I was expecting this from everything I've read, and I will reserve my judgement until it has properly warmed up/run in.
Question: Can I run this amp laying on it's side?

Question: Can I run this amp laying on it's side? I owned three of them running my three T1 towers, I never found them bright or harsh but I did buy them used, if that has any effect, after those I also owned a Class D amp which was a D-Sonic and also used B&O Ice Modules and sounded amazing but sold it as I had too many amps haha, the PA-1 should be fine on it's side if needed as I never noticed mine even get that warm playing at louder volumes for lengthy periods of time. Cheers, Chad |

So having sufficiently 'warmed up' the PA-1 now and doing some A/B testing between my Rotel RMB-1095 (just the centre speaker for testing purposes) I am really liking the sound of the PA-1. The vocals are slick and detailed and seem to really pop out of the speaker more than with the rotel which seems quite laid back almost lazy in comparison. I have tried to eradicate any anomalies such as the PA-1 being fully balanced would have more input gain (Rotel only partly balanced) so I have adjusted the volume either down for the PA-1 or up for the Rotel on this centre speaker channel. The rotel is extremely smooth in the mid-mid/high trebles which is great but almost boring? It could be that I'm so used to it(had this unit for 12 years now).
There's something I like about the way the PA-1 just pops out of the speaker as though the person is right there, but I still need more time to decide if this is going to be fatiguing for long term listening. Its' tricky as there is still plenty of depth to the sound its not like it's some cheap amp using treble to get your attention, its certainly a high quality amp no doubts
Expectation bias is a difficult thing to overcome. I want to like the PA-1 because a few of them will solve some lounge room issues for me.
I really am close to pulling the trigger on a bunch of 'em...............
As a side note:
I'm thinking of putting 2 in the roof cavity to power my ceiling speakers, mad or genius? I can run balanced cables to them which eradicates any interference that speaker cabling might pick up, and that's 2 more amps that have "Disappeared" from view. Only downside I can think of, is the dust up there.

How HOT does it get up there? I know that in mid-summer here in SoCal my overhead easily exceeds 100f for HOURS at a time and probably a LOT hotter. I'd expect 120 maybe or even hotter?
Look at amp specs and it probably is not rated for such conditions. Cool running is one thing, but cooking it quite another.

Only downside I can think of, is the dust up there. What you're hearing is the speed of the amp. the PA-1 is exceptional in microdynamics, close to the level of the XPA-1 gen 2 which I own imo. What it means is that it is able to The only other amp I've heard that can do this is the XPA-2 gen 2. So it's in very good company. Over time, the treble will sound a bit more laidback in tone, give it a few more days. (Just make sure to turn off the auto off function). I agree there is something special to this amp. When I first got it, I couldn't believe that this tiny little amp was sounding very close to my 70 pound monoblocks. Over time, I realized that, hey this was the real deal. Where else can you get a fully balanced monoblock that sounds anywhere near this good or is so small and lightweight at this price, right?! |

Look at amp specs and it probably is not rated for such conditions. Cool running is one thing, but cooking it quite another. Ah good point, in summer here in Adelaide it gets pretty hot, average is around 30c (86 F) but we usually have a week of over 40c (104F) and last summer it hit 47 (117F). I imagine the roof would get pretty hot. |

I imagine the roof would get pretty hot. Outside temp is ONE thing, the heat load and actual temp in the overhead is quite another. Here where I live, it gets above 90f maybe 5 to 10 days yearly. But I've been in my attic during hot weather and thought I was going to die! It was so hot up there that when I opened the 'hatch' for access, it started a huge updraft. And because it was so bleepin' HOT up there, the breeze felt cool. Even though my house was in the high 70s.....maybe even 80f. Even though the amps run fairly cool, I'd STILL not stress 'em by putting them in a hot place. Just for example? I've sprayed my ROOF with the garden hose. It dries almost too quickly too get it evenly wet and you can see the 'steam' rise..... |
