What are hifi reviews useful for? (1) Identifying products you should demo in person at a dealer. (2) Learning which products reviewers unanimously praise as the best they've heard (this means they probably are legitimately great). (3) Identifying a product's attributes that satisfy your idiosyncratic needs and tastes. Beyond that, we often discount what reviewers say because they heap praise on most products—and are often apprehensive about publishing strong criticism or comparisons between products. Further, they seldom have more than a few products on-hand, often relying on their memories to compare past products. Always listen for yourself.

Stromtank
S-1000
15975
/
Released
2022
Everything that distinguishes the StromTanks can already be found in our smallest model: a mains-independent generated perfect sine wave for the best sound. Whereby „small“ should not be considered underpowered, because the entry into the StromTank world can also be the perfect choice for many. Depending on the system configuration and listening habits, there are no limits to absolute music enjoyment with the S1000-SourcePower. The main reason for this is the LFP batteries, and in the case of the S1000-SourcePower we are using 8 batteries (24V System). Due to their high cost, they have not been utilised in the audio sector so far, but they are extremely powerful, durable and safe. That is precisely our claim. Given the impressive dimensions of the StromTanks, it may seem almost ironic to say, but they are comparatively compact thanks to current battery sizes. Just a few years ago, the dimensions of a comparable device would have been simply absurdly large. If you prefer to listen to classical music with HiFi system that is not oversized, the S1000-SourcePower is your StromTank. By the way: even when our StromTanks are charging, your system sounds better. You don‘t believe that? You don‘t have to, you can hear it. Connect your system to the S1000-SourcePower and give it and yourself a few days. You will no longer want to listen without a StromTank.
Stromtank is unique among power conditioner brands for completely disconnecting audio systems from the power grid and using lithium iron phosphate batteries to deliver pure sine wave power. Their battery management system, developed with the Fraunhofer Institute, actively monitors and balances cells while handling both front-end and power amplifier components, unlike typical power conditioners that only support low-power devices.
Expand Details
Our Summary
Product Strengths
- Provides cleaner, more stable power to high-end components
- Improves color saturation and transparency
- Increases soundstage depth, width, and height
- Makes the music more real and live
- Lowers the noise floor, allowing more low-level detail to be reproduced, and a more coherent AC sine wave to be supplied to the equipment
Product Considerations
- The Stromtank S 1000 emits a quiet hum
- The 450VA continuous output power is not sufficient to deliver full power via some monoblock amplifiers
- The batteries will last roughly 15 years before energy storage drops by 20% if recharged once per day
Comparisons (according to reviewers)
- Compared to the AudioQuest Niagara 7000, the S-1000 provides more silence and space, and allows reverb around vocals to be more discernible
- With Stromtank battery power, the Dan D'Agostino's ability to convey detail increased to darTZeel levels, and its soundstage magic increased
Takeaway: The Stromtank S-1000 helps reveal the full potential of audio components by providing cleaner power, resulting in a more engaging and detailed listening experience. It can make a significant and noticeable improvement to soundstage depth and clarity.

Gryphon
Powerzone 3
17906
/
Released
2024
Forget everything you know about signal processing: compared to all other Power Conditioners, Gryphon PowerZone 3 introduces a unique and entirely superior way of improving the signal passing through it. In an electrical circuit, current flow is attended by micro-vibrations on a molecular level; basically, all current flow is, by definition, the transmission of energy through micro-vibrations.
Gryphon is one of the most respected high-end amplifier brands in the world. Its bass grip is phenomenal, thanks to an unusually high level of capacitance, which keeps everything tight and controlled, even with demanding speakers. Gryphon is also known for its bold, brutalist design—a look that a lot of people love. You’ll find their gear all over Europe and Asia, and the Diablo 333 is often considered an ‘endgame’ amp by those chasing the very best sound and aesthetics.
Expand Details
Our Summary
Product Strengths
- All the instruments became clearer and better focused with the PowerZone in the system, with noticeable bass improvement
- The PowerZone optimizes the electrons' vibrational flow and minimizes spurious resonances and the distortions they create
- Music playback was described as 'more comfortable' with familiar recordings delivering increased width and depth
- The PowerZone helps the signal flow in a natural way, by using a better adapted environment
Product Considerations
- The PowerZone 3 is an expensive product
- The review mentions the reviewer changed two things at once in a demo: adding the conditioner and changing power cables
- The reviewer notes that the theory behind power products and how they work in tandem with a system is impossible to predict
Comparisons (according to reviewers)
- Vs PS Audio P20: The PowerZone produced a very different experience, with one friend commenting 'Where did the bass come from?'
Takeaway: The Gryphon PowerZone 3 can improve the clarity, focus, and bass of a high-end audio system, resulting in a more comfortable and enjoyable listening experience. It is an effective addition to power conditioning products.
