The 27/72 Room Setup

That' the key to sound quality retrieval, not the brand a person buys

And this alignment is done physically, aided with computer software and laser alignment with my registered trademark Brand technologies AVT AUDIO 

No room Correction DSP nor acoustic treatment can fix a result of incorrect physical alignment, to retrieve sound quality improvement.

Any brand can only deliver up to 30dB gain, go look in your amplifier specification.

Most are only 28dB of music out of a 75dB audio input signal. The rest is electromagnetic radiation noise and acoustic alignment problems and vibrations,

My technology solutions achieve about 60dB out of 75db
