Not sure if this is the right section for this question but I was wondering if anyone knew of a cheap headphone amp for my PC.The headphones I'm using are the Sennheiser HD 280 PRO.The motherboard I have is the MSI Z68-GD65(G3).I've seen something like the FiiO E5 Headphone Amplifier,which is great for the price but I'm looking for something less portable.
