Is the sound of ATL plug performing the best?

He is making a joke - and a good one (but left out covfefe).

Please don't waste your money on this.  Buy better speakers, or better room treatments, or better masterings or recordings of your music.

thank you for your comments. I will change other audio equipment to save the money. thank both of you anyway. get nearby market..

Usually, the best thing to do is to upgrade your speakers, or add better room treatments.

Best Wishes
