Which came first, the chicken or the egg

Where do you start? Building HT system (Budget $50K New discounted or used). Just finished ASC's WALL DAMP SYSTEM. Now need quality built and sounding electronics. Something recognized by audiophiles (just in case I turn into a junkie and want to dump it in a few months without getting killed, or laughted at). Value priced and not obsolete before its broken in. Tube or transistor but would like 7.1 capabilities. 75% home theater, 25% good stereo listening.
JUMP IN ! Put a system together and be ready to defend your picks to your death, or yield to someone more experienced and knowledgable.(I've read some of the posts, it can get nasty). You have been challenged.... who's first?
