Op-AMP vs Bridge Rectifier for VU meter

So, I'm finally getting around to adding some toys to my system. One of them is this:

Bought it a long time ago for way too much money, but now I want to cannibalize it for the VU. I have noticed that the circuit that came with it included a quad op-amp. I don't care about accuracy, this is just eye candy, but I dont want it to cause feedback and what not. The interwebs have pointed me in two directions - one using the op-amp IC and the other using a simple diode rectifier with a resister and a cap. Obviously this is easier - but will it cause me problems for my simple project? My intention is to unsolder the VU meter from that circuit and wire it up internally - perhaps off the Audio Header on the motherboard.
Thoughts?
