I like seeing music posted here as well.
I am running out of space so I will probably gift a Valhalla 2 and a couple Dacs to friends and maybe some interconnect cables. I still need to build another Coaster amp in a flying saucer motif if I ever get free on weekends. It should amuse my son and delight my granddaughter when completed. I need to find a tiny music activated LED controller since flashing LED's are a must in this build. This is just a fun project, and I will most likely incorporate some Christmas music, Mannheim Steamroller.
The controllers are easy to find and I have some extra headphone drivers laying around, this may end up being a self contained device that is more of a light show than a headphone amplifier. I have some thin DAP's that could be mounted underneath to feed the Coaster amp. It does not need to be very loud and it is mostly to please a child so sound quality is not a driving factor.
@CAPT Deadpool if this works well I will help you build one for your kids. It needs a speaker output of some type to activate the LED's.
