I am using an old Denon AVR3200 for HT. Instead of upgrading to a new AV receiver, I decide to get an intergrated tube amp (Melody SP-3) mainly for music. I am thinking to connect it to the pre-out outlet of the Denon to share the front speakers, even for HT (I am not going to get another pair of front speakers). I don't know if it is OK to use the tube amp for HT. Please comment! Thanks!
