The Monica Zetterlund pre/phono by Lars of Sweden landed at our friends at AE. It houses a phono stage inside as well. Unlike Japanese top tube preamp offerings Monica is a true balance differential design in two chassis. Volume control is unconventionally in the same chassis with the power supply. Amplification circuits are housed separately in an independent chassis. Monica preamp also utilises a push pull circuit. The Sweden school of thought is interesting and enlightening at the same time. And to make things even more interesting The Monica apps on iPad/iPhone remotely control the Monica preamp.
