A classic all-valve push/pull power amp, the 150 delivers 150Wpc in tetrode mode and 70Wpc in triode operation. Sonically the amp delivers plenty of wallop, but is also capable of fine dynamic shading, excellent resolution, and great overall coherence, with the attendant bloom, air, and texture tube lovers desire.”
