Question about Adcom GFA-5500 2-Channel Amplifier
Adcom makes a great amplifer! Usually broken highs and no bass means blown speaker. Try hooking it up to a completely different input source. Try different speakers also. If problem persists, check the fuse. Most will have a fuse on the back you can screw out. Some have two fuses (one for each channel) If this doesn't fix the problem it could be expensive to fix. Also, does this model ave the thermal protection light and if so, does it come on at all?

I had a similar problem with a faulty capacitor. Clipped bass and strange static was worse at higher volumes. It may be in your speaker or in the amplifier. Search bad capacitors on google for examples . If they are bulged on the top they are bad. Simple fix if you can get to them.
