same here Alex, think i have 3 990 and and the top one with cd, can't remember model number but she has electronic volume and 4 band eq, ahh yes the dt 690
Yep, Rah-Rah, and 3-way speakers.. CT-990 is a bit better IMO - she has line-in, plus you can always put another box on her top.. No way with DT-680..
Yep, I like the CT-990 way better, too, for the same reason. I also think it's fun that I can control the volume on both units at the same time with the remote for the DT-680! (which is the only remote I have for them)
