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

@cincyjim  I had the 2v2SE & that is a great DAC but I was too curious so purchased the Anniversary model & it's fantastic. Tremendous detail but still smooth. I recommend you try it...
But...I'm considering a significant jump to the Aqua Formula xHD... although I'm not sure I can justify spending that much on a DAC.

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.
