Music suddenly sounds wrong, no dynamics

Hi All,

Happy for your input on the following. Running an Ayre V5 and K5, source is an old original Musical Fidelity V Dac wired over USB to an even older Macbook, music is stored on an external harddisk.

System has to date sounded very very good. Saving to upgrade to an Ayre QB9.

As of last night, my system can no longer play "complicated" music as it used to do. Diana Krall / voice only is sounding good as always, but with multiple instruments like classical concerts and Coltrane Live in Birdland are completely....wrong. Shallow tones, shallow mid bass, rhythm seems off, very weird. Can't listen to it, so much wrong with it.

Before this happened, I noticed that the speakers were no longer as "pitch black silent" as they used to be.

Any ideas what component has died on me / is fading out here?

Warm regards,

Hi All, the electrical system in my appartment is shoddy (e.g. lamps may fall out at times) -- could that be driving this?
My first guess is the electrical but it typically comes and goes with the electrical usage. Did this occur after someone recently moved in? If possible try to 'borrow/demo' an re-generator and not a battery back up.

Sorry but what does 'lamps may fall out at times mean'? Sounds to me like it might be gravitational and not electrical.
Given your description, I take it that this is a problem that is constant. Like Xti16 said, if it was a power issue, it would probably come and go. You need to isolate the problem.

Have you made any changes to your system at all? Even if its something very small like changing IC's. If not, still go over your system and check all the connections and make sure everything is as it should be. If your speakers cables are connected out of phase, that could easily be the problem.

My first guess is that the problem does not lie with the Ayre equipment. It may, but I would be surprised. Moving to your speakers, I would suggest 2 things. 1. Go over each speaker and make sure all the screws are tight. They can loosen up over time. 2. Go up close and listen to each one and make sure that whatever the problem is, is effecting both speakers.

Next, I would go the computer. Look at all the settings in the OS and related software and make sure everything is all properly configured. For example, you may be set for 5 channel HT instead of 2 channel stereo. Even if you didn't make any changes yourself, sometimes upgrades can mess up some of your settings. Also, if you find nothing wrong with your PC, I would still substitute it with another source, just to be sure. Hook up a cheap DVD player, or something similar. It doesn't have to be anything high end, you're just using it to check for anything major.

Try connecting your source to a different input on your preamp. Also, if you have any other components that can substituted in the system, just to rule out good components, do that too.

See if any of that helps and then post back.
I would look at your hearing. Do you have allergies, a cold, build up of wax in your ears? All of these things can cause the symptoms that you are hearing....or not hearing as the case may be.
