Digital Music sounds too bright?

The blanket is not great.  Absorbing things between the speakers is not a good thing.  Better to have scattering.

Instead, I use two 1/4 round tube traps from ASC in Oregon.  I locate these next to the screen with the rounds pointing inwards.  The screen simply dissappears acoustically because the backwave from the speakers is scattered.  I've been doing this at shows too , even when there is no screen, locating them behind and inside the speaker lines.  Improves imaging.

Another critical thing is to have absorbers, like acoustic foam, on the side walls to absorb the secondary HF reflection.  Put a mirror on the wall and if you see the tweeter from the listening position, you need foam where the mirror is.

BTW, brightness is not usually due to acoustics.  Its usually something else.  Most people go down the garden path using cables that act as filter, ferrite beads or blankets to snuff-out the HF sounds.  This is the wrong path to take.

Figure out what components are really at fault.  Usually excessive jitter from the source, whether computer or CD player, or poor preamp that adds too much distortion and has poor power delivery or even sometimes a bad DAC.  This is typical.
