Audio tax write-off

Hello,

I have a company that produces documentaries and podcasts on personal and commercial histories. I have needed to acquire computer equipment to do my work, and I've borrowed some equipment from my 2-channel system, such as headphones, as well. My question is, do any of you write off home audio audio acquisitions for your business? Do you know the tax rules on this? Does it have to be branded  as "pro" gear to qualify? Thinking I need a better DAC and studio monitors. If I bought a component called "Schiit," would the tax auditor go "nnnnnnnnnnoooooo?" 

Thanks for your input.

Paul
