Or could it be the port? ...They are vented right?

Vented port? Oh! You mean let the port breathe before you drink it, right? I'd rather stay with the beer. All my music sounds better with beer .... ;D

Jackfish,
On the topic of changing your transformer:
Chances are pretty high that swapping in a larger VA transformer will cause problems unless you really understand the design of the amp. First off a larger VA rating means a larger sized transformer, you'd need to check for space requirements. If you're going for more current capability then your output devices (MOSFETS most likely) will need to be able to handle the extra load. Also, with the extra current will come extra heat. Your heat sinks will need to be large enough to handle the extra generated heat under load.
In other words you need to know the amp design quite well before you swap in a larger transformer.
Never mind that you'd void any warranty

I'm pretty certain your issue is related. Well you’re the acorn expert

Really? A digital clock with a plastic craft eyeball glued to it? WTF is that garbage supposed to even do? I am seriously in awe of this level of stupidity. You didn't read their tech info on it LOL www.machinadynamica.com/machina42.htm

I'm sure somewhere there is someone who would respond to your post with, "Hey, I'm not saying this is for everyone but it worked for me. Don't knock it until you've tried it." ;D You know, I think I could make more money with that same product if I advertised it as a weight loss device.

You know, this is a very low risk business they have. It is probably just one or two guys who think of stuff like this. One sends an e-mail to the other with his latest idea and the other responds with ROTFLMAO, then they go to the nearby 99 Cent Only store, buy the materials they need and put it up on their web site. Meanwhile, they have regular jobs but then once in a while some sucker actually buys it and some extra income comes rolling in. It really costs them nothing.. and with web sites being so cheap, they don't even have to pay for ad space. All they have to do is pay for the domain name and the hosting on a server. Genius! ;D

Did I say this sh** makes a difference. No. All I said is try it for yourself. Do I think things could make a difference in ones set up and could someone enjoy tweaking. Yes. How about this, you try it for yourself, form your own opinion on the topic, otherwise shut up. The OP asked for anyone who tried these mods, you guys came out saying oh its just all crap and discouraged someone from even trying it. At this point you are bashing and its getting old. You sit there and whine when people come onto this forum and say they don't like Emo products. Yet someone could have an opinion that differs from you regarding speaker cables, power cords, tweaks, etc and its fair game to have people take it and run. I'm pretty *bleep*' sick and tired of seeing this sh** over here. Do I care if you like my stance, no. At this point I'm done, and this is a waste of my time. You try to give someone good pointers of how they can try something for a little bit of money, and then everyone jumps on the "oh its all snake oil" bandwagon without even trying it. You know you can pick up a used PC from signal cable easily for 35 bucks and resell at the same price...but rather than trying it out, seeing if it would make a difference, you give people crap and say they are full of it. If you really don't think any thing makes a difference, once again. Buy your CDP from wal mart, get a pro audio amp from a garage sale, and get wal mart speakers. Why? because you wasted all your money on this stuff because it wouldn't make a difference now would it?

I don't think he was making fun of you specifcally. Reading his post didn't come across that way to me.
I think he was just stating that in the audio world, there is a lot of smoke and mirrors about niche products making big changes in systems and companies charging a fortune for them.
With all things there will be those who believe they can hear a difference using X or Y and others who don't. The debate over what is real and what is imaginary can only be defined by each individual.

No offense to anyone, but life is short, and money is tight. So if some idea, which is supposed to improve the sound takes time and/or money to test out, I personally would never waste either IF this "tweak" defies science.
Power cables, for example. A new one costs money. It makes no sense that one could improve the sound, when said cable is connected to 1000's of feet of ordinary copper with transformers, and fuses/circuit breakers and such in the path as well. Can I prove it won't improve the sound? No. But I also don't think it's worth spending a single minute or single penny on testing the concept.

Crazyhorse, Calm down bro. None of my comments were directed at you or any other person on this forum. All of them were directed squarely at the company that sells bags of beads you scotch tape to your interconnects to achieve better sound quality. As stated, I don't even see how this companies products are audio related at all. None of these offerings even make sense. Changing fuses, power cables, transformers, ect. are all parts of the amps electric/signal path. Those changes could very well have an affect on any given amplifiers performance. If it does or not, I am unaware. I do not have the technical know how to begin altering my electronic devices. I never said, nor insinuated, that any legitimate mods to Emo (or any brand) amps would/would not have an affect. Take care, relax, and if you decide to do some mods to your amps then I would seriously be interested in hearing about your results. If they aren't too expensive, too difficult to do, and can make an honest audible improvement then I would do it to my amps as well. I leave all of that tech stuff up to the guys with the experience and knowledge of why and how to do these types of (legitimate) mods. -Dave

Why? because you wasted all your money on this stuff because it wouldn't make a difference now would it? Well I apologize as I wasn't directing my remarks at you. I was talking about that company that makes that stupid clock device and the bags with trash inside of it. I wasn't talking about the mods you mentioned. Personally, I don't believe in those things but I am not going to ridicule you if you do; just because I don't believe in it personally does not mean I am sure I am right or you are right, that's just the way I look at it based on my thinking. That said, if you were to try and defend the things that I WAS making fun of (that clock and the bag of junk), then I would out and out say you are nuts. ;D Something like that is ridiculous, and my remarks about how someone would say "don't knock it until you've tried it" were directed at people who were so stupid that they actually believe a senseless thing like that could work. So if you believe in that nonsense, I don't apologize. ;D Instead I would say why don't you make your own device that suits you, like a *bleep*oo clock. But really, I was not directing anything at what you had suggested trying.

Crazyhorse, relax a little bit. It didn't come across to me that anyone was insulting you in any way. Tweaks are fun, this is a hobby. Bead bags are silly though, everybody was getting a kick out of that sillyness, thats all.

Crazyhorse, I was a card carrying skeptic regarding interconnects many moons ago, until I actually tried a pair that made a significant improvement in a system I used to own. I still use these interconnects (Harmonic Tech TruthLink) between my CDP and preamp in my all new system. Back in those days, I auditioned many interconnects and can tell you the differences between them when the rest of the system remained constant. I believe that some of the sound is system dependent, and some of it is wire dependent. I am a strong believer in system synergy as well. I kept my curiousity at interconnects for a long time, thinking there is no possible way in all of this great earth that a power cord can make a difference after many miles of grunge, noise, interference, etc on the eletrical that comes into my house. It defies common sense and logic. I then discovered a company called Signal Cable which manufactured economical upgrades to power cords, interconnects, etc. I bit the bullet and tried a power cord to the amp (not an Emotiva-this is my old system) and CDP, knowing that I can return it if I did not like it ( a potential risk of under $10). The difference was obvious and instantaneous. The sound became clearer, more dynamic, with the effect of sounding punchier and cleaner. It woke up my system. I cannot explain why I heard the difference. My only explaination is that the factory power cord was somehow inferior in some way but I haven't cut them open to compare. I am a convert, but am not interested in purchasing aftermarket power cords for my XPA-1s because I am not at all compelled to see if they can be improved by power cords (besides-I'd have to buy two! ). Anyways, I am one who knows of what you speak from the experience of actually trying some of this stuff. I still cannot explain why it works and am still baffled that it does work. As far as hotrodding the XPA amps, I have no engineering background, but I think the easiest mod would be to trade out the caps. I personally would never do that because, like I said, I have not been compelled to try to improve on the already superb sound of the XPA-1s. Anyways, that's my two cents worth... By the way, those rocks in plastic bags are funny! Ha Ha Ha! I am not so adventurous that I am even going to contemplate such a tweek. Anyone interested in improving on the sound of their current interconnects will probably get more mileage by crossing them at 90 degree angles, though that can be physically impossible due to the thick nature of interconnects these days. Just thinking out loud. Take it for what it's worth. crusty

Crazyhorse ,Every one here is just having a little fun and not at you expense it was at the other products shown , but I also apologies to you if it cam off that way also I have tried fuses , power cables and spacial speaker cables at one time or another that friends have brought over for me to check out and for “my friends and I ” they made no difference what so ever ,but that doesn`t mean someone else wouldn`t, these things are very subjective and at the prices they are asking there are far better ways to improve you system like room treatments for one so I would tell anyone try that first, again sorry if it felt like we where singling you out and I`m suer every one here will agree that that was not are intention .

hmm sounds like 1 of type of nerd web sites that sells a nerdy product that have virtually no function what so ever other than just to tell time or just a novelty product...

Never mind that you'd void any warranty What you are saying makes sense but I do wonder... As I understand it, the amp module in the UPA 1 is the same as the amp module in the XP3 and the XP5. The power transformer in the XP3 is rated at 850VA and the one in the XP5 at 1200VA. Dividing these ratings into the number of channels gives the UPA1 transformer a higher capacity than either the XP3 or XP5. BUT Music volume and spectrum however is usually constantly changing so its entirely conceivable that at anyone time a substantial portion of the transformer output is in fact going to only one channel or two. That being the case and since as far as I know XP3 and XP5 don't have a reputation for blowing up, I suspect that this amp module is designed to take substantially more than the 300KVA of the UPA 1. Just a hunch but I suspect that with a beefier transformer and considering that it has 80,000 pf of capacitance, the UPA 1 would get uncomfortably close to the XP2 from a marketing standpoint
