I'm having trouble finding the Eden website. I think its eden-engineering.com...but its not letting me go there on several computers. Also, how does a 2x10XLT with WT-600 Road Runner. I know this is overkill with the preamp, but I might expand to add a 15 later. Are there better preamps for this...I would like to use one or both cabinets with the preamp. Thanks.
