Some times we "decide" the sound quality based on the label we are seeing in that moment and not in what we are listening.
I must say as a former owner of a Durabrand HT-390 (or something like that) that this "HT" (at least for me) worthed every penny I paid for it ($80 in México in 2005) and more, the bass for a 5 1/4 is impressive, satellites´ sound quality sucked, but still was an improvement over my TV speakers, there was no Dolby, only stereo sound with a simulated Dolby sound effect.
When I first listended my HTIB Denon, the sound compared with the durabrand was not very different, for a moment I thought that I wasted my money for almost nothing, with time and some use sound improved, but not much, had to change speakers for Pioneer´s Andrew Jones line so listed a big difference.
I´ve read that many durabrand devices where faulty, but in my case never had a single problem for 6 years, I believe I was lucky. This HT is stored in a box, may be I´ll use it with my pc.
