DAC Bandwidth settings


Hi all
I have looked on the net but can't see a simple explanation to describe the differences between these bandwidth settings on my DAC:
• slow roll off, linear phase
• slow roll off, minimum phase
• fast roll off, linear phase 
• fast roll off, minimum phase 
• apodizing fast roll off, linear phase 
• hybrid fast roll off, minimum phase 
• brickwall  

My DAC is Wyred 4 Sound Anniversary 2v2SE Limited Edition.

Thanks 
Rich

I assume use are using an ESS chip, it’s datasheet on pages 55-58 shows the graphs for the frequency and impulse differences for all 7 (doesn’t show phase though), page 53 shows the tech specs.

Apodizing fast is the default for most DACs.

Keep in mind that, while it depends on the DAC, most people I’ve heard from can’t hear a difference, maybe a minute one. 
 
I would experiment between Apodizing and Fast Linear

I find it odd the tech specs for the 10th anniversary edition is exactly the same, granted the specs are not extensive. Would like to see these measures to see what  they improved to warrant ~2x the price.
