Is a AV Receiver really necessary?

[james.miller]

PC Speakers are no match for an AV system. Their specs are generally incomplete (they rarely if ever show what distortion level, how many channels driven, or what frequency range was used during the test).

THX by itself is meaningless, Infact all THX is really is a set of filters that Lucas likes personally. Me, I find a THX filtered soundtrack to be extremely lacking in high frequency response, and have my AV Processor's THX filters disabled. The only time I enable THX is when an old 'badly recorded' movie has a lot of hiss, the THX filters do tend to reduce it a little.

THX cert goes far beyond a set of filters, Corasik. there's a whole list of parameters equipment has to meet to gain THX certification, at least on anything other than a set of pc speakers.

If your Logitech sub/amp blows your unit is useless.

I realise that, I was oversimplifying. That said, THX most certainly does force a low pass filter onto the gear, and I am very pleased that my THX approved processor permits the disabling of the THX filters. The system loses so much high end detail when the filters are enabled.

My amp passes THX Ultra 3, but it would not make the slightest differenence to me if it was not THX approved, as it exceeds THX's requirements anyway.

agreed there. I have the THX re-eq switched off on my onkyo, also. there's a good write of re-eq here that shows just what its doing. 3db down at ~12khz, and 5db down at 20khz.
