Alternative IR emitter??

The Slink-e IR transmitter has 5 IR emitter LED's on it - see http://www.nirvis.com/images/ir/tx%20module.jpg (I have an older pre-modular one, but it still has 5 LED's). I have all my IR sending devices (a 3025 ChannelPlus video modulator with built-in multi-room IR routing, a TV with an IR sender, and the Slink-e) in an enclosed box pointing at an IR receiver for a a HotLink (see http://www.hot-link.com ) audio cabinet IR routing device.

I've had problems with the Slink-e IR not being consistently recognized by my A/V devices. Since the HotLink amplifies received IR quite a bit, it occurred to me if the Slink-e 5 LED emitter was sending the IR very bright to start with, this might be swamping the HotLink or the device IR receivers.
