Compare the Grado Aeon4 and Sonata4 phono cartridges. Find out which one fits your system and budget based on output options and channel configuration.
Quick answer
Choose the Grado Aeon4 if you want a top-tier Lineage cartridge in stereo or mono and are comfortable with a special-order/no-return purchase. Choose the Grado Sonata4 if you need flexible output options (high or low) and a more accessible price point in the Timbre series.
Series and price differences
The Aeon4 belongs to Grado's Lineage Cartridges line, which represents the brand's highest level of design and materials. It is priced at USD 3696.30 (catalog comparison USD 4995.00) and is offered as a special order item with no returns. The Sonata4, part of the Timbre series, costs USD 444.00 (catalog comparison USD 600.00) and is available in multiple output and channel configurations, making it a more flexible and accessible choice.
The price gap reflects not just the series but also the purchasing commitment: the Aeon4 requires a deliberate, no-return decision, while the Sonata4 is a standard stock item with free shipping.
Configuration options
The Aeon4 is available in Stereo and Mono versions, both special order. The Sonata4, on the other hand, offers High-Output and Low-Output versions, as well as Mono versions in both output levels. This makes the Sonata4 a better fit for systems that need specific voltage matching or a dedicated mono cartridge without jumping to the highest price tier.
If you need a mono cartridge for archival playback or vintage records, the Sonata4 Mono (high or low output) gives you that capability at a fraction of the Aeon4's cost.
Trade-offs at a glance
- Aeon4 – Ultimate performance, limited flexibility: The Aeon4 is a special-order Lineage cartridge with no returns. It comes in stereo or mono, but offers no output-level options. Its high price reflects the best materials and design from Grado. Choose this only if you are committed to a top-tier cartridge and have a system that works with its fixed output.
- Sonata4 – Versatile, affordable, and stock: The Sonata4 offers high-output, low-output, and mono versions in the Timbre series. It is a standard stock item with free shipping and a much lower price point, making it an accessible upgrade or system-matching choice. Ideal for those who need to match output level or want a mono cartridge without a special-order commitment.
- Mono on a budget vs mono at the top: Both cartridges offer mono versions, but the Sonata4 Mono (high or low output) costs a fraction of the Aeon4 Mono. The Aeon4 Mono is for the enthusiast who wants the best possible mono playback regardless of cost. If your mono source is not your primary system, the Sonata4 Mono delivers excellent performance at a much lower investment.
