Project Description

THRAX ENYO Mk2 Modular Audiophile System, £10,995

Enyo is Thrax’s vacuum tube single chassis modular Audiophile system. A cost effective one box Integrated amplifier with Integral Dac, Phono preamp and streamer. First released in 2017 and now upgraded to Mk2 guise for 2022 Enyo is an ingenious distallation of Thrax’s reference level products to produce a highly versatile unit of extremely high sonic ability. While the DAC module can accept data up to 32-bit/384kHz and DSD128, the integral MM/MC phono stage provides 40bd & 60db of gain with switchable loading. Enyo is designed for speakers with a recommended minimum sensitivity of 87–88dB and will operate at 4–5 watts 95% of the time so it’s rating of 50W is ample for all both the most demanding of speakers. Pure, organic, truly neutral with startling dynamics and musical insight, Enyo is a true space saving High End solution perfect for the UK market.

Power amplifier used in Enyo are a completely new design based on our research over the last 10 years. It is a 3 stage fully differential architecture. The output stage uses the rare arrangement of  cathode feedback while retaining the usual ultra-linear  connection of the pentodes. This required the design of a special output transformer wound on double C core GOSS. Driving this output stage called for the development of a special front end circuit accommodating positive grid swing. DC coupled tubes are rare but Enyo uses a single capacitor in the signal path.

 The input and driver tubes used are our favourite 6n6p. While the output stage duty goes to the GU50. The Gu50 tube is based on Telefunken LS50 but made by the Soviets for the radio communication in the MIG planes. This is evident by looking at the socket locking the tube from falling out due to heavy vibration.

Luckily they made a lot of them and the tube is available worldwide for a very reasonable cost for the quality it offers. 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 mono blocks.
