DO NOT BOTHER installing XLR's... just get either XLR to RCA cables or get some Cardas XLR to RCA adapaters.
Modifying the amplifier will reduce the value also. The other option you could do is to sell your current amp and buy another amp with XLR connectors. But just because a piece has XLR adapters doesn't mean it is a fully balanced piece of gear. If the item isn't truelly balanced than RCA to XLR adapters will provide the same level of performance.
