Help! Treble Trouble!

@thecarpathian - are your ear canals clear of obstruction? The obstruction may only affect specific frequencies.

I once had a doctor who used a syringe who used a lot of pressure to blast out my ears- gave me the knowledge of how much pressure is safe. So now every few months I use the pulsating feature in my shower head to rinse out my ears several times. I believe that once some water is on the eardrum active a cushion to additional water pressure. For my kids, I use an ear syringe and use a lot of pressure.

Could be your speakers, so maybe test for high frequencies. The easiest free option may be to get someone else to listen to evaluate. 

Sounds like wired out of phase…

Plus, it happens on two different pairs speakers.

@thecarpathian Rereading this, it does appear that you have in fact tracked it down to the DAC. Obviously, remove it from the chain and retest. 

When did the lack of treble start? Was it a gradual change?  Did you just get a couple of 200# dogs? As an aside, I have a buddy who put so much sound absorption in his room it almost sounded creepy when you had a conversation and sounded dead and really dull when he played symphony recordings.
