What reviewers think

Magazine reviewers and YouTubers have tried this product—so we've summarized their strongest opinions below.

Product Strengths

  • Uncanny ability to place both instruments and vocalists in their own space without the presentation as a whole feeling crowded or compressed
  • First-class clarity and purity in the treble region, enabling one to hear the tinkle of a pin drop in even the busiest of mixes
  • Prodigiously extended, solid and taut bass that remains composed even when the amp is driven hard
  • Makes a great job of poor recordings, managing to impart a sense of order to the proceedings and even bring a hint of purity to the ragged top end

Product Considerations

  • An absolute unit, weighing 41.2 kg which strongly suggests a two-person lift, and those persons might want to wear gloves as the edges of the heatsinks are not exactly smooth to the touch
  • Takes a while to come on song, and really only comes on song when the heatsinks are warm to the touch, which can take anything up to half an hour or more
  • Thermally-induced changes in distortion mean that it's more important than usual to allow an adequate warm-up period after switch-on before settling down to any critical listening

Takeaway: The Donizetti Anniversary is a powerful amplifier with a refined and controlled sound. It's a good choice for audiophiles who value strong performance and the ability to improve the sound of less-than-perfect recordings.

How useful are hifi reviews? We consider them useful for three things: (1) Surfacing new products you should demo in person at a dealer. (2) Learning which products reviewers unanimously praise as the best they've ever heard (this means they probably are legitimately great). (3) Identifying a product's unique attributes that satisfy your idiosyncratic needs and tastes. Beyond that, we  discount what reviewers say because they heap praise on everything—rarely being negative for fear of souring relationships with manufacturers. Further, they seldom have more than a couple products on-hand at once, relying on their imperfect memories to compare to past products.

Our take on the brand

Audio Analogue is a hifi brand distinguished by their ABsolute integrated amplifier's unique dual-mode operation, which lets users switch between 50W pure Class A and 150W Class AB with a button press, while using zero global feedback circuits for enhanced sound purity. Their Italian-made amplifiers are known for adapting to different music styles, as demonstrated in their Maestro Anniversary integrated amplifier's chameleon-like sound character and the Primo Settanta's ability to create a three-dimensional, emotionally realistic soundstage.

What reviewers think

Magazine reviewers and YouTubers have tried this product—so we've summarized their strongest opinions below.

Product Strengths

  • Uncanny ability to place both instruments and vocalists in their own space without the presentation as a whole feeling crowded or compressed
  • First-class clarity and purity in the treble region, enabling one to hear the tinkle of a pin drop in even the busiest of mixes
  • Prodigiously extended, solid and taut bass that remains composed even when the amp is driven hard
  • Makes a great job of poor recordings, managing to impart a sense of order to the proceedings and even bring a hint of purity to the ragged top end

Product Considerations

  • An absolute unit, weighing 41.2 kg which strongly suggests a two-person lift, and those persons might want to wear gloves as the edges of the heatsinks are not exactly smooth to the touch
  • Takes a while to come on song, and really only comes on song when the heatsinks are warm to the touch, which can take anything up to half an hour or more
  • Thermally-induced changes in distortion mean that it's more important than usual to allow an adequate warm-up period after switch-on before settling down to any critical listening

Takeaway: The Donizetti Anniversary is a powerful amplifier with a refined and controlled sound. It's a good choice for audiophiles who value strong performance and the ability to improve the sound of less-than-perfect recordings.

How useful are hifi reviews? We consider them useful for three things: (1) Surfacing new products you should demo in person at a dealer. (2) Learning which products reviewers unanimously praise as the best they've ever heard (this means they probably are legitimately great). (3) Identifying a product's unique attributes that satisfy your idiosyncratic needs and tastes. Beyond that, we  discount what reviewers say because they heap praise on everything—rarely being negative for fear of souring relationships with manufacturers. Further, they seldom have more than a couple products on-hand at once, relying on their imperfect memories to compare to past products.
