Hi,
I use my XPA1's for stereo listening only and they really sound great.
I was wondering if I could improve on the sound. I guess I'm looking for a little more of everything and specifically a little more refinement.
Has anyone tried replacing all the fuses with 'hifi' ones or changing the caps or powercords, etc?
I realise it wont be an issue for people in the US etc but I accidently reversed the polarity when testing out some powercords and make the amp sound bright and the soundstage depth and width was very contracted. So they are sensitive to polarity changes.
I'd be very grateful for any suggestions/ helpful comments,
Cheers!
jimi

IMO those changes are not going to make any difference...but it would still be a cool project to try.

I see. If true, it would certainly make life easier Please could you explain why you say that?

Power cords and hi-fi fuses are internet myth nonsense.
What interests me is your "reversing" of polarity. Are you running them at 115 or 230 volts?
Nieither should make a difference, just wondering.

I totally agree. But some will argue this till they die. lol I was also wondering about reversing of polarity.

try it and find out yourself. PC that you can try you can find by Signal cable or the Pangea are a very nice build and fit. Some people hear differences, others don't but try it for yourself.
Also upgrading Fuses etc can be an improvment. Once again try it for yourself. PC's are easy to find on the used market and don't lose their value when bought used so can be sold again at the same price bought.
Try it before knocking it. Others will argue till the day they die that it doesn't do anything without ever trying it, goes both ways.

I'm not "knocking it" just stating fact. My osciloscope is way more sensitive than my heaing will ever be. According to it, the electron path through a fuse or power cord is the same regardless of how it is branded or the price put on it. The only notable difference would be if your power cord is literally getting warm due to resistance. In that case a larger gauge would lower resistance.
As far as reversing the polarity, I am running mine at 230v. Emo amps do not use the neutral lead, or ground lead in the 230v instance. If running 230v there is no way to reverse polarity. You use 2 legs at 115 volts each.
This is being the case, the amp should not notice any difference at 115v either if the polarity is reversed.
Placebo is a powerful thing.

Quoted from Emotiva's Manual "Inventory Included with your X amplifier should be an IEC Class 1, 2 prong power cord, and this User’s Guide. Emotiva amplifiers are double insulated and do not require a grounded plug. Much care has been taken to make sure that your amplifier is safe, completely shielded, insulated and grounded." So for those curious to test this reversed polarity. Get yourself a cheater plug (one without the third ground leg) and you can "reverse" the polarity all day by unplugging it and rotating the plug 180 degrees and plugging it back in. You will not get shocked and/or burn your house down. Please post your findings.

Yes, you have to take into account the non-measurable aspects of any upgrade that digs deep into the wallet - psychology. ;D

And you guys are not bashing how?
Once again, try it. Oh wait your too busy trying to make fun of those that do like to try things. Not everything is in #'s or tests.
Once again all I did was say to try it, and yes you are knocking it because you pretty much say that nothing will make a difference. Then why bother even buying the Emo amps at all. Just go buy some used pro audio gear at a junk sale, or better yet buy a wal mart CDP. Its not going to sound any different.
I just love how open you guys are to anything different. Useless.

Just go buy some used pro audio gear at a junk sale, or better yet buy a wal mart CDP. Its not going to sound any different. I just love how open you guys are to anything different. Useless. In the world of audio there is a ton of SUBJECTIVE opinion and I understand this and accept it. A group of people can listen to a speaker and hear 15 different things. Everyone's perception of what sounds "good" is exactly that, a perception. Some look for brilliant shimmering highs, some appreciate warm full mid-range, and others find audio utopia in tons of mid-bass pounding them in the chest. We are all different and the bottom line if YOU are happy with your system, that is all that matters. That being said, a bigger piece of this puzzle is SCIENCE. It is testable, proveable, and simply put... FACT! I don't care how God-like your bazillion dollar amp is, it is not special enough to defy Ohm's law and sound "different" with a $1000 power cord. I walked out of an install once after about 2 hours of a customer insisting to me that his amp "came alive" with his new $1000 power cord and that I was an idiot for thinking otherwise. I let it go for 2 hours, then snapped. I pulled the outlet cover & receptacale. I unwired it and asked him if this .59 outlet and the 75 feet of 14ga. Romex were also worthy to supply his audiphile reference power cord. It is always said that a chain is only as strong as its weakest link. Fancy fuses, power cords, and overpriced speaker wire will not defy the primary laws of electricity. This is not subjective, it is fact. So many of us in this arena spend so much time arguing about minute details between amps and avr's and interconnects. This all pales in comparrison to the giant amount of distortion in speakers (all of them) and the absolutely terrible room acoustics that we subject our systems to. We spend thoudands of dollars on the latest greatest thing and never address the obvious. My apoligies to you if you felt my joke about the rocks was a jab at you. Yes, they are rediculous. Anyone with a firing synapse can decuct that a pebble on your floor is not going to change your room acoustics. What I stated about the polarity is fact, yet I emplored everyone to try it if they wish and even posted a way to do so without chopping your cord. By all means try it! I am not opposed to expirementation. Hell I ran a 230v line to my amps this weekend just to try it. .... and to prove that absolutely no one has read this far into my endless rant, tonights winning Lotto numbers are 36-25-02-18... oh forget it. ;D

I couldn't leave this one alone. That is just asinine. If you would like to experience clarity and openness from your system that you never thought possible, I've come up with a specially patented formula for acorn caps. That's right folks. I said acorn caps. Your jaw will hit the floor when you hear what these acorn caps can do for your system. Just attach one double acorn cap to each interconnect with the supplied audio grade tie wrap. I guarantee that once you try these acorn caps you will never run your system without them. Invite your friends over and be prepared for the many "WOWS!!" that will follow. These exclusive audiophile grade acorn caps are truly something special. Try a couple and find out for yourself what makes them so special. So what gives with these caps? How do they work? They open end of the caps act like ears and pick up sound waves from the room. When the sound waves pass through the special formulation inside the caps they restore the "air" and "spaciousness" that gets lost due to limitations of the recording, source and room. Here's the best part, I will send you as many as you like for only $59.00 each with free shipping. That's $20.00 off the regular price. But don't wait because this offer is only for a limited time. The first 100 callers to order 2 or more sets will receive 1 free set. CALL NOW!! 1-500-226-7663 (1-500-AcornMe)

You are soon to be a very rich man.

I'd buy the acorn caps, but I use balanced outputs instead of single ended.
