If your amp, speakers and speaker cables are ok, maybe you can try a different CD player to see if it's not him the problem ???

CD Player,Rega P5 TT,etc

Do you try with headphone to see if the problem will be the same.

I never play music loud
I have an apartment in NYC & downstairs neighboor

Interesting, I thought you said you resided in rural NY? Just a thought, have you checked your power supply? Maybe you are experiencing AC current issues.

Did you buy this speakers new or used?

If new, they will still be under warranty and get a new pair as your dealer can back you up on your claim. However, if foul play is detected upon inspection from PSB the warranty will be voided.

If bought used and there is no warranty then, you will either have to send the speakers in for inspection/repair or you will have to buy new ones. Either way you will be spending some money

I had a pair of Synchrony II
The crossover was changed-
Still did not remedy the problem.
I sold them,purchased brand new ones(they were discontunied for $2000 pr.)
The new psb synchrony II have the same character
Bass is sometimes there,if I get a connection just right
Quickly changes like a chamelon to inferior bottem end & less power
Makes no sense..
The only constant is I'm not listening to music much
It's too fustrating

Hi,
I had similar issues with my speakers Epos M12.2
After initial connection for about half an hour to an hour everything is just fine, and then like someone with a magic stick change the character of the speakers. With my current PMC no issues at all. Maybe some kind of reactivities caused by the crossover. I can't find which order is the PSB, but my Epos were 1-st order.

You're the first person (in the universe) to cooberate my story

A long shot, but could you have reversed polarity , at the speakers or amp? Might be worth revisiting.

apoid1 · « **Reply #31 on:** 21 Nov 2012, 01:04 am »

Speaker & amp connections have correct polarity

mkaiser · « **Reply #32 on:** 21 Nov 2012, 06:44 am »

Sounds like you need to purchase a new pair of speakers based on all the facts you are providing.
If you must have these speakers then explain to PSB.... if they can't help you then move on to a different brand... you are obviously stressed and there are lots of great speakers in your price range.
Good luck apoid1

PS - tonight all of a sudden i can't get bass out of my Martin Logan Spires bass modules but, everything powers up and shuts down with no issues just no bass coming through.... so i feel your pain.

Hi,

Not that I can exactly 'corroborate' your problem, but I do experience a related 'issue' with longer periods of listening. Initially, the soundquality coming out of my system is heavenly. And per definition always a break from my other ongoings and their related mindset.

And then, after say half an hour, I tend to start hearing a different sound quality, or at least interpret it differently. At first I found that annoying, (in fact I still do) and started searching for a reason, and of course a solution.... Tried all individual elements in the system, and I can not hide the fact that the purchase of the new BHA1 was partially justified because of that. I even tried my old kef102's to replace the ESL63's, and in that mind-set (or should i say ear-set) at that time I felt they sounded better

All elements seem to be perfect. The BHA1 is heavenly, as is the rest of the system.But even with the BHA1 after a longer period, my ears 'hear' differently. Rules out possible issues with my ESL and pre-and pro amps. Will try the ModelT as soon as it gets here though

Summing up, I must believe the culprit is our own Mind(set), and possibly our hearing mechanism. Because of that, I read some psychological theories pointing in that direction, but right now can not find their links, sorry.

I think it was comparable with the well known effect of looking at a red picture for a minute, and then closing your eyes, or even more evident, a white paper. Your brains show you the opposing component color belonging to the red picture. Apparently something like that is happening in experiencing sounds also. Experience a different sound when closing your eyes? Or try this: like a dominant eye, you might have a dominant ear. There's all kind of situations where we think we do things 'stereo' but in fact point one of our sensors in a more prominent way, depending on our complete physical state of that moment. Humans are the variable here

The other day, I was at a concert where Reich's WoodenMusic was performed. After 15 minutes of clicking Claves, the applause sounded completely weird in my head, up to the point I felt a dizzyness coming up.

Trust your B135, even your Speakers, but always doubt your own ears and mind....... You're not alone

Good luck,
Marius

I must also have brainwashed my girlfriend
Because she hears what I do
But I accept your theory as relevant

Marius · « **Reply #35 on:** 21 Nov 2012, 02:06 pm »

don't take my word for it, this article points to what I was referring to http://www.cycleback.com/eyephysiology.html

try this one, amongst many others, on the Psychology of hearing http://svconline.com/mag/avinstall_psychology_hearing/ :

"Conclusion In the past, approaches to sound perception have tended to focus on low-level factors, such as thresholds for pitch and loudness and masking functions. Recently, however, the importance of higher-level, cognitive factors has become increasingly evident, and there is growing recognition that the auditory system of the brain contains some remarkably ingenious circuitry-perhaps the most ingenious of all the sensory modalities."

Might be totally irrelevant to your problem, but still, its a nice read.

Only thing I go through is like after a short period after turning on and listenng is they could be a bit loud and I turn em down.
