Testing equipment

A while ago, I seemed to notice there was a lack of low frequencies on the left side of my system. At first, I blamed the room. I have since moved my speakers into a pretty ideal room, and still have the same issue.
I would like to make sure this is my ears and not my equipment.
The vocals seem to be in the right place, but there seems to be more sound on the right side. A while ago, someone mentioned testing voltage on the amp outs to make sure everything is matching. Considering my equipment is pretty old, I probably want to do this. How do I go about it? What other things should I look for when checking out my equipment?

Just switch the left and right speakers. Change nothing else. Does the issue follow the speaker or does it stay the same?~ In search of accurate reproduction of music. Real sound is my reference and while perfection may not be attainable? If I chase it, I might just catch excellence. ~

Sorry, I forgot to mention that I have switched the speakers before with the same result. I will switch them tomorrow along with any other tests I do (like flopping cables and channels and what not)
Last time I checked this out, I flopped amplifier channels (I believe) and the problem went over to the other side. I don't trust my memory, so I will do this again tomorrow. I was kind of hoping to get some hard evidence... I remember someone saying about using a multimeter to test voltage. -
Start again if you don't mind. Troubleshooting is hard enough online as it is. Lets eliminate some things as we move along.
Next thing you want to try again is the swapping of the RCA outs on your source and nothing else. Same question applies. Does the sound follow the speaker or does it stay the same?
Just be sure to do one thing at a time. Thanks.~ In search of accurate reproduction of music. Real sound is my reference and while perfection may not be attainable? If I chase it, I might just catch excellence. ~ -
Man, I've tried for an hour and I can't hear it today... I need to test it when it bothers me again. If it keeps coming and going I'm gonna have to further question my hearing.

Switched speakers. No difference
Switched channels on dac. opposite
Switched Channels on Amp. opposite -
Treitz3 has asked you a question and you have to be accurate and specific in your answer(s) (as pointed out, it is very hard to help troubleshooting online).cokewithvanilla wrote: »Switched speakers. No difference

When you say no difference when you switched the speakers; do you mean problem stays on the same side (channel) or do you mean problem stays with the speaker despite the switch???
The above statement may lead to an intermittent connection (be cable which you swapped or even connector at of some of the equipment could also point to intermittent problem within the speaker (specific mid driver)).Man, I've tried for an hour and I can't hear it today...

What sources are you using?
Sorry, I forgot about this thread.
When I said "no difference" I meant just that, no difference at all. The sound did not move to the other side. Opposite meant that it did.
I am using Computer>HRT Music Streamer II>Aragon 24k>Adcom 5800>Tyler Acoustics monitors -
Ok, this is all very unscientific, so I just tried something. I used the same cables for each test, unplugging all other cables. I ran one speaker at a time using various configurations. I would try using the left channel of the amp versus the right, using the left output of the pre versus the right. I kept the source on the left channel at all times seeing as it is stereo output. Here were my results:
Amp Left, Pre Left, Source Left, Speaker Left = 71.6
Amp Left, Pre Right, Source Left, Speaker Left = 70.8
Amp Right, Pre Left, Source Left, Speaker Left = 70.8
Amp Right, Pre Right, Source Left, Speaker Left = 71.2
Amp Left, Pre Left, Source Left, Speaker Right = 72.1
Amp Left, Pre Right, Source Left, Speaker Right = 72
Amp Right, Pre Left, Source Left, Speaker Right = 72.3
Amp Right, Pre Right, Source Left, Speaker Right = 71.7
The reading is the HIGHEST point in the passage. I used the track Zakarum from the Diablo II soundtrack. I played from 1 minute to one minute 21 one for each test.
I then simply switched the speakers for one test (I accidentally adjusted the volume a bit here)
Right Speaker on Right side = 75.1
Right Speaker on Left side = 74.1 -
is it fixed now? have you figured it out already?

Maybe I missed it but what's your unit of measure here? Measured db? What is the accuracy repeatability of your measuring device? Making a lot of assumptions, I would say your results weren't too bad, with the emphasis on "assumptions". Also not familiar with the source you are using, but I have had some recordings that were not mixed the best in the studio.
