Kari Nevalainen has posted a review of the MasterSound Piccolo integrated amplifier (~€1800) at Innerworld Audio. His conclusions:
Mastersound Piccolo was an interesting new acquaintance. My feeling is that it will easily occupy some market niche where good-looking, good-sounding tube integrated amplifier is needed. Unlike the Almarro 2050A, which I would not select as an integrated amp even though it has a volume pot (excellent as a power amp), Mastersound Piccolo is a throrughbred integrated both functionally and sonically.
