Cheapest volume control

I'm strongly considering selling my Peachtree Nova Pre in order to get a Schiit bifrost uber but I'll need some way to control volume. I was previously using a Lightspeed Attenuator, which I loved.

I was thinking about just buying s Schiit SYS for the time being. Is the SYS going to be a let down? I really only have about $100 to spend on a volume control right now. I only need one set of inputs and one set of outputs. I dont have to have a remote control. I'm just looking for the best sounding option.

My current amp is a Peachtree 220.

Thanks for your help! I appreciate it.
