Spent 19,500/- on a Sony dav 510. it has just come into the market as a substitute for the outgoing 390k model. It has some slightly different features. I had checked this out vis a vis Sony 390, 290, Onkyo 3100 and phillips 3571. celine dion "power of love" for 2 channel sound and eagles "hotel california" for 5.1 sound and PQ. I like my bass tight and loud.
IMO phillips had the richest and best SQ. followed by the 390, 290 and 3100, went for the sony view its brand image and service. installed at home and viewing thru a samsung 29" slim. I'm happy and satisfied (for now).
Cheers
