“what is the effe - 01”
@rivinyl 

Both ENO and effe -01 offers 30 days money back guarantee. If we’re in your shoes, i would order both and compare them side by side. That’s the only way to know for sure that these devices offers any audible benefits in your system. 

I am quite impressed with the extent of responses my question has stimulated.  Drilling down a bit it looks like perhaps an optical power isolator may be the most cost efficient way to go.  Again, in my analogue brain it looks like the iFi Silent Power 2 is a similar device, in theory, to the effe isolator.  Any chance anyone has had a experience with both?

Also, a respected dealer/ friend who used to sell Network Acoustics products found them to compress dynamics in his system.  As much as he enjoyed working with them he ultimately stopped carrying their products.  Has anyone had a similar experience?

I have found that iFi is entry level at best. 

Save your money and dive in head first.
