Product Considerations
- Limited features for its price, lacking an internal DAC, room correction, or bass management.
- Small, non-standard form factor might not match other hifi equipment aesthetically.
- Limited to one balanced input and one balanced output.
- Reviewers noted a chintzy plastic remote that needs to be synced.
- Sensitive to cable changes and may exhibit high-frequency noise if XLR cables are not connected
Comparisons (according to reviewers)
- The Alto was equal in sonic performance to the Amped America AAP-1, but the AAP-1 has dead-neutral tonality.
- There is not a lot missing between the Alto and the Bricasti Design M20 preamplifier in terms of sound, but at a little more than double the price, the Bricasti Design M20 had better dynamics and ultra-fine resolution.
- Both the Alto and the Pass Labs XP-12 stereo preamp are very high-end stereo preamps that do just that—do what they say on the box.
- Trilogy's set emerged rounder, bloomier, more massive, and atmospheric against the quick snappy team AGD that prioritized dynamics, outlines, clarity, and had its spatial projections sensibly more oxygenated.
- The Alto is like the Anthem without the DAC and streamer.
Takeaway: The Alto preamplifier is well-engineered to provide clean, high-quality sound, and it's a good choice for audiophiles who prioritize core preamp functions. It offers great performance for vinyl and digital sources when additional features aren't needed.
