The speakers I listening to are the B&Ws 803 D3, they have a max of 300w. If I look at the amps that there are in the world then for example a Bryston 4B3 has 300w, but the Esoteric S-03 has only as its max 30w. Both can sound the B&Ws wonderfull but how can this Esoteric do this with only 30w...

I ask this question because I see/hear different places where the ser.no has to be. Also I can not find on the website of A&K a check page/register page. Already thanks for your answers.

Hi I'm a new member here that's why I can not post this in the right thread. My question is: How can I format a 256GB microSD card to FAT32? I asked this because this isn't possible with WINDOWS10 (only exFAT and NTFS). But A&K recommend FAT32, but how? Already thanks for the answer.
