Our take on the brand
The Thrax Enyo packs all of the above optimized to interface to each other in a single bulletproof chassis with timeless design to deliver the sound you want with the features you need without the clutter and unnecessary expense.
The power amplifiers used in Enyo are a completely new design based on our research over the last 10 years, with a fully differential 3-stage architecture. The output stage uses the rare arrangement of cathode feedback while retaining the ultra-linear connection customary for military pentodes. Driving this output stage called for the development of a unique front end circuit accommodating positive grid swing. DC-coupled tube amplifiers are rare but Enyo uses only a single capacitor in the signal path delivering that "triode' magic without the usual "tube color". The power supply for the amplifier uses choke filtering to guarantee pitch black backgrounds and freedom from power supply modulation. Those are features rarely seen in anything other than top quality tube monoblocks. Autobiasing makes tube replacement a breeze.
The preamplifier in Enyo is our newly developed input board handling the input selection and volume control duties. The signal path is fully differential with transformer isolation for the inputs. Ground switching prevents any interaction between components connected via RCAs as it is intended for use in the average household with no dedicated power lines. The preamplifier board now hosts our MM/MC phono stage with menu selectable MM/MC and cartridge loading making the Enyo a top analog performer. The input board has its dedicated analog and digital power supplies totally independent from the power amplifiers, making it a complete world class preamplifier in the same box. The large LCD screen keeps you informed of the current settings easily read from your listening chair.
For Home Theatre integration we have added a "bypass" feature allowing you to use the Enyo as your speakers' power amp including a screen dimming function not to distract you while watching a movie. And on top of that it can be programmed to use with your favorite remote reducing clutter on the table.
The optional DAC extends the input range of the preamplifier by accommodating all modern digital interfaces - AES, SPDIF, Toslink, USB, Ethernet and Bluetooth. It hosts a 32bit/768kHz/ DSD256 dac. The dac itself is discrete build around switched resistors and dedicated power supply making it yet another separate component in the same box.
The streaming module supports multiple protocols, sample rates and signal resolutions up to 32bit/384k and DSD256. It is Roon Ready.
Enyo is a way of getting rid of cables, multiple remotes and boxes scattered across the room, so when we say it is a modular audiophile system we mean it. Zero compromise with no cable clutter and extra space. Each module optimized to interface with the other in the system guaranteeing synergy of the highest level.
Product Strengths
- Delivers a large degree of presence and dynamic potential, sounding pressurized and potent
- Has a very engaging way of conveying musical interrelationships, contributing to a strong sense of realism
- Neutral and faithful in its reproduction of music
- The DAC is very organic and analogue sounding, with not a hint of any digital signature, and dimensional, joyful and bold
- Good for driving difficult speakers through its particular circuit and excellent stability
- The front soft-touch buttons are very sensitive, which can lead to accidentally switching the amplifier off during power-up
- Care needs to be taken when switching to the digital input
Product Considerations
- The front soft-touch buttons are very sensitive, which can lead to accidentally switching the amplifier off during power-up
- Care needs to be taken when switching to the digital input
Comparisons (according to reviewers)
- Vs Thrax Ares: The Enyo has extra body and depth of tone, making it the more appealing amplifier
- Vs Vitus RI-101 mk2: The Enyo has lessened tightness, and the music feels like it has been allowed a little more freedom, and there is a sense that it is holding nothing back
Takeaway: The Enyo Mk2 is a versatile all-in-one tube amplifier with a neutral sound that brings out the details and timing in music, making listening sessions enjoyable. The optional DAC is a great addition for those seeking a single-box solution.
