A best-seller because it effectively balances high-end Italian craftsmanship with an accessible entry point into the world of pure Class A valve amplification. It is the modern successor to the legendary Simply Two, one of the most successful tube amplifiers in history. Praised it as an "entertaining listen" with a "sparkling" performance on jazz and vocals. The reviewers noted that while it lacks the raw energy of some transistor amps, it counters with a rich and informative high-frequency response.
