Seems right hand side is louder, need helps

Dear Audiophiles,
Need helps from U guys! I have this problem comes on n off for about 1.5 year. I owned the spk Avalon Eidolon. My problem is everytime whenever I turned off the power, I need at least 2 or more days to recover the centre of the vocal, which I use the XLO Test CD, which can tells u left ,right,n centre, phase.
However just about 3weeks ago, I found the right hand side tends to give louded volume, this thing never change ,even I never turn off the power atall, also I cannot get the voice from the centre. This really boarded me alots. Where I test the power amp output curent, bothside have the same voltage, where one of the track in the CD has for both side equally.( Mono ).
This Maybe due to the placement of the SPK as I thought, however I tried many times, it just can't work out. I really hopes someone may helps out there at Audiogon. My problem is: The vocal keeps going to the right about 1foot from the centre.N I can feel the right hand side sounds louded, but when I went close to the spks abt few inches, it seems to me both side the same.It is really headache toi me. Will be very appreciate if someone would share the experience.Thanks! N Happy listening to u guys! ****** Cheers! ******

This is a semi-quibble with Sean but nothing serious. If you are doing the XLO measurements with their test disc, then you are using a simple tone directed to the left, then to the right speaker, and measuring the amplifier output voltage as the system plays, i.e. under load. In this situation, if the voltages match (and I have to borrow voltmeters from work to get to the millivolt ranges they are referring to), then you are accounting for all the upstream contributions, so you wouldn't need to go through switching components. Reseating cables periodically is still a good idea (and cleaning terminations, while you're at it).

If you are using balanced interconnects, make sure that the are fully inserted. If one of the hot pins is not making contact you might loose 1/2 of the input signal for one of the channels and throw the system out of balance. I had this happen, turned out to be a bad xlr connector. Good luck, Bob D

I heard nothing from the right side 3 weeks ago and almost panicked.It turned out to be one heck of a sinus infection on that side that also had me going to the dentist because I thought a filling fell out, it hurt so bad. Decongestant and antibiotics later, things are back in order. Also, on the smaller side of things,sometimes I think the couch gets moved off center by the kids or the dogs. Balance control helps here until the couch gets recentered. Sometimes those speaker wires work loose as well and need tightened. Can tubes going bad create the same thing?

Hi! Guys,
First of all, I would like to thanks urs helps, I really appreciate. However, I tried many methods but still failed. Hopes u guys can give me some more adv. on it.
( Still using the XLO test CD )
1st step : I tried to swap the inteconnect from left to right, n right to left, just to be sure no problem from my front sys.It happen the same, the center vocal still tends to go to the right. About 1 foot.
2nd step : I swap the speakers, same works , L to R, R to L, , however it still the same, Center goes to the right, stay at the point 1 foot.
3rd step : I swap the speaker cable, same works, L to R , R to L, n yet it still the same, center vocal goes to the right.
4th step : I move around the speaker, just can't work out. I had tried many movement, but failed.
So My Q is that, if I want to get back the vocal to the center from the right, wht shd I do, I had the identical on both side, as this sound room was special designed to be identical, on both side of the wall, as well as ceiling, floor carpet, from wood wall.. Thanks again from the fans above , n just need more adv.Thanks again!

Cheers!
Mike

I had exactly the same problem. It was my room. Try moving speakers forward if possible, and try some sound proofing at the first reflection (doesn't have to be large). My balance is fine now. Good luck!
