way better..there are testings done,before u can get a thx certification ..thats why,mahal ang mga thx recievers..
THX certified equipment are expensive because they have to pay Lucas for the THX royalties. THX is a certification process to tell the world that the product conforms to THX standards. A wee bit better than an ISO certication.
But if you read many DVD reviews on the net, you'd be surprised that some reviews of THX certified DVDs don't pass at all and even questions how THX came to certify so and so lousy DVDs. While there are laudable technical standards behind it, some on the net have opined that the THX logo has evolved into a marketing tool to better attract buyers.
For me, I don't bother at all with THX logos in DVDs. I just read technical reviews of the DVD I like to learn how a DVD release perform. With regards amps and receivers, if I recall right, the THX minimum standard is 100wpc for power. Hence, there are many sub-100wpc amps that don't carry the THX logo like many HK models. But I can assure you they sound incrementally better than some 100wpc recievers that do. It seems to me that the THX certification is no guarantee of better sound quality. Just an indication that the product conforms to some set of standards so they can work with other gears with the same THX certification in synergy. That means one should use a THX-certified DVD player to connect to a THX-certified receiver to drive THX-certified speakers in order to max the synergy or to properly claim you are benefiting from a THX-certified set-up.
Actually, to really max out the synergy, you should invite Lucas engineers, all expenses paid by you, to also certify your video set-up, room accoustics and speaker placement as THX compliant.
The same way they certify a theater as a THX theater using only THX-certified lighting, screen, accoustics, video and audio gears. Then you can probably max the use of THX-certified DVDs.
