Lexus need to upgrade the GX Mark Levinson Amplifier like TX

[Caiya]

I had the dealer address the rear rattle on my GX today and requested the new ML amplifier TX as the loaner.
As a GX550 owner, I must say the new amplifier delivers much deeper bass, a more immersive sound field, and punchy low-end response. However, the active noise-cancelling is a bit too aggressive and makes the cabin too quiet(which we definitely need!). And, after an hour driving, it makes me a little dizzy. Overall, though, it’s a fantastic upgrade in every respect! I hope Lexus releases a TSB for the GX as soon as possible. I can’t wait!!

Makes the cabin to quiet and makes you dizzy but we definitely need it?

Sounds like a new slogan for a low end Tequila distiller -

Is this a direct retrofit?
