You will find there whole two pages about Ferrum ERCO and OOR. Some great quotes are here below:

“VERDICT: If you want a headphone amp that plays it brilliantly simple, the OOR is bound to please with its direct, communicative delivery via a wide variety of partnering ’phones”.

“Ferrum’s ERCO sits at the top of the hill, typically driving headphones to stunning effect whether with gritty blues or whirling orchestral strings. It has focus, finesse and control, but a heart of iron too”.
