I thought this was clear but I am interested in a different two channel pre-amp with better sound quality than a Sonic Frontiers Line One. I do not want to upgrade it.Smart move! I've had many SF pre and amps ... last was Line 3SE+ and Power 3SE+ upgraded to the MAX by PCX. In hindsight should of just replace them instead of wasting money on the upgrade. SF was good in its time but no comparison current offerings.
