Product Strengths
- Build quality is in tune with its luxury-goods price tag, and styling is the very soul of mature understatement
- The circuit layout is tidy to the point of being unabashedly beautiful
- Physically beautiful in a Bauhaus sort of way
Product Considerations
- Incorporates New-Old-Stock (NOS) parts into the design
- Inputs are low-mass Switchcraft RCA jacks, which apparently offer desirable electrical and thus sonic qualities in compensation for what they lack in reliability, which may require users to keep spares on hand

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.

Bryce
16000
/
Released
2021
The story of the Bryce was an extension of our work with the Nautilus integrated amp. The Nautilus integrated how special single ended amps could sound. Where the Zions represent ultra bandwidth push pull mono blocks the Bryce monos our are Ultra wide bandwidth single ended amplifiers with an output that opens them to most speakers with moderate efficiency. The Bryce’s mono layout allowed room for innovative thinking with the inclusion of a fixed bias structure and moderate feedback. The Bryce exacts the maximum output from a single power tube through high bias and gentle feedback. Wired as true Tetrodes feedback was used to extend the frequency response and maintain operation closely mimic triode curves.
ampandsound specializes in high-end, handcrafted tube amplifiers made in the USA. Their low-wattage amps pair perfectly with high-efficiency speakers and headphones. The company is known for classic, minimalist designs and a focus on delivering natural sound.

Expand Details
Our Summary
Product Strengths
- The EHT combines tubes and transistors to mate the most desirable characteristics of both
- Amplifiers provide fullness and density, even at low listening volumes
- The EHT creates a natural sound with incredible saturation
- They are fully short-circuit proof at the outputs without any sound-degrading protection
- A switch-on delay is omitted because switching on/off develops no disturbing noise or dangerous signal in this circuit
Product Considerations
- Sound is focused on timbre rather than detail
- Their sound is soft rather than focused, rather warm than open, and rather close to us than presented in a perspective
- The devices are quite large, as they measure 434 x 184 x 434 mm (W x H x D) and weigh 14 kg each
Takeaway: The Thöress EHT monoblocks offer a holistic view of the musical material and its reinterpretation that can be very enjoyable for long listening sessions. They create events in their own acoustic environment, which is completely transferred to the listening room, creating a beautiful, organic, comprehensive, and internally properly arranged sound for those who value tonality above all else.
