Do these manufacturers at least recommend the use of an expensive isolation device, cord, fuse , cable , etc.. in order to get the best sound from their devices? They can leave out specific brands if they feel uncomfortable recommending them but in at least a generic sense do they recommend one go out and purchase these things so their stuff will perform better? I'll email the maker of my amp and see what they recommend. They spent the R&D building the thing, I am not an engineer or designer of these things, I assume they know what they are doing so I'll trust their advice and if they say yes it will improve them then I can consider if I want to spend my money on them over a consumer proclaiming yeah I spent $5000 on tweeks and damn they work great!!
