The next step in line PBN level amplifier coming closer to perfection. Peter Noerbaek writes: “Our original idea was linear system 489/689 which are good – however with 103/246 it’s special – will do 74/170 tomorrow the ones in the know will know the references above. Erno Borbely your teachings in the past 25 years are invaluable this is what Les Bordelon and I have come up with from your teachings. Thank you.” The new line level amp will replace the LXI and the LI shortly.
