My music sounds brighter

Hello all. All of a sudden my music sounds brighter whether I'm listening to a record or a CD. I do have to turn down the treble a bit to compensate for this and make it pleasurable to listen to. Nothing has changed with my electronics which consists of a Yanaha DSP A1 integrated amp, DBX 3BX DS dynamic range controller, Pro-ject Debut Carbon turntable with acrylic platter and Ortofon 2M Blue cartridge, Wharfedale Rubiance RB 27 floor standing speakers in the front and RB 23 bookshelf speakers in the rear and a Mirage FRX S15 subwoofer.

I would have thought that if I was experiencing any deterioration of my electronics, it would be in the opposite direction with a decrease in high-end response.

Any thoughts? Thanks.

Just a guess, but have you added any big power guzzling appliances lately? Has a big power draw come online in your city?

If so, the solution may be an isolation transformer. Trouble is, they tend to growl when working, so they should be sited in a utility room. Plitron makes a good one.

I set up my audio system 1.5 years ago. I've made no changes in the room since.  I have the room temp at 70 degrees and humidity at 50%.  I started noticing the brightness about 2 weeks ago.  And no, I don't drink!

Just in case, I would clean all the connectors.
This might be the current, I don't know, I have never experienced anything like that.

Are you air conditioned? What was the change in the weather?

We live on the west coast a couple of miles from the beach. August is always a bad month for the HiFi as the listening room gets into the mid 20�°s.
