I purchased SPL Volume 8 to establish a multichannel monitor speaker system. It receives audio signal from my desktop computer sound card and then feeds the signal to my monitors. Well, this sounds simple enough but without Volume 8 I suffered from severe noise and the lack of matching volume control.
To be honest, I am surprised that Volume 8 can reduce the noise by so much which my other amplifiers were not able to handle and even worsened.
I like the fact that this product does not have a power indicator light or anything else when in normal operating conditions, only a red mute light would come on when you depressed the mute button. However, you would forget about it and leave it on all day without noticing quite easily.
DB25 snake cables are expensive and it's hard to find a exact fit for your system but you can always make your own with a fraction of the price and yet higher quality.
