I've just finished the Moreplay pre-amp and am interested in doing the crack headphone amp. Obviously I have my sources plugged into the moreplay, would it be a simple case of running a set of leads from the Moreplay outputs to the crack amp outputs ?
Yes, you can cable up the second set of Moreplay outputs to the Crack inputs. You may find that the volume pot on the Crack needs to be somewhere around 50%-75% rotation to allow for the Moreplay to be used in this way without things being overly sensitive.
