Built as the purest expression of the Echo concept, it keeps the focus exactly where it should be: handcrafted Polish tube amplification, a warm and natural presentation, and strong synergy with high-impedance headphones.\u003c\/p\u003e\n\n\u003cp\u003eAs a simplified version of Feliks Audio’s best-selling Echo platform, Echo Classic is made for listeners who want the tube experience without paying for extras they may not need. It delivers the rich midrange texture, smooth treble, spacious imaging, and easy musicality people expect from a well-built OTL tube amplifier, all in a compact desktop design with classic wood side panels.\u003c\/p\u003e\n\n\u003ch3\u003ePure Tube Sound, Made More Accessible\u003c\/h3\u003e\n\u003cp\u003eEcho Classic is designed as a gateway into premium tube audio. It is not overloaded with features, switching options, or unnecessary complexity. Instead, Feliks Audio has stripped the formula back to the essentials: a clean signal path, a proper OTL tube circuit, carefully chosen tubes, and enough power for the high-impedance headphones that pair best with this kind of amplifier.\u003c\/p\u003e\n\n\u003cp\u003eThe result is a headphone amp that feels immediate and inviting. Vocals have body, instruments carry natural texture, and treble stays smooth without losing air. It is the kind of sound that makes long listening sessions feel relaxed and immersive rather than clinical or fatiguing.\u003c\/p\u003e\n\n\u003ch3\u003eBuilt for High-Impedance Headphones\u003c\/h3\u003e\n\u003cp\u003eEcho Classic is optimized for headphones from 80Ω to 600Ω, making it a natural match for many of the dynamic-driver headphones that tube amp fans love most. With 350mW of output power and 20dB of gain, it has the voltage swing and character needed to bring out the richness, scale, and tonal density that make high-impedance headphones so rewarding.\u003c\/p\u003e\n\n\u003cp\u003eThis is where OTL tube amplification makes the most sense. Pair Echo Classic with the right headphone and you get a presentation that feels open, full, and human, with a touch of warmth that flatters without smearing the music.\u003c\/p\u003e\n\n\u003ch3\u003eClassic OTL Character\u003c\/h3\u003e\n\u003cp\u003eOTL stands for output transformerless, a tube amplifier design that removes the output transformer from the headphone signal path. For the listener, that design can translate into a more direct and expressive tube sound, especially with medium to high-impedance headphones.\u003c\/p\u003e\n\n\u003cp\u003eEcho Classic uses a pair of driver tubes and a pair of power tubes to deliver the kind of sound Feliks Audio is known for: smooth, spacious, slightly warm, and naturally detailed. It gives music a sense of weight and flow without making the amp sound slow or overly soft.\u003c\/p\u003e\n\n\u003ch3\u003eSimplified Construction, Feliks Craftsmanship\u003c\/h3\u003e\n\u003cp\u003eThe Echo Classic is intentionally simple, but it does not feel basic. It is handcrafted in Poland with the same attention to fit, finish, and long-term reliability that defines Feliks Audio’s higher-end amplifiers. The compact metal chassis and wood side panels give it a timeless desktop look that feels equally at home in a focused headphone system or a smaller office setup.\u003c\/p\u003e\n\n\u003cp\u003eBy keeping the design streamlined, Feliks Audio makes the Echo Classic easier to place, easier to use, and easier to recommend as a first serious tube amplifier. No clutter, no unnecessary extras, just the core tube experience done properly.\u003c\/p\u003e\n\n\u003ch3\u003eKey Features\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003eEntry-level Feliks Audio OTL tube headphone amplifier\u003c\/li\u003e\n  \u003cli\u003eMore accessible version of Feliks Audio’s best-selling Echo platform\u003c\/li\u003e\n  \u003cli\u003eDesigned for high-impedance headphones from 80Ω to 600Ω\u003c\/li\u003e\n  \u003cli\u003eClassic warm tube sound with smooth treble and rich midrange texture\u003c\/li\u003e\n  \u003cli\u003e350mW output power\u003c\/li\u003e\n  \u003cli\u003e20dB amplification level\u003c\/li\u003e\n  \u003cli\u003e15Hz to 45kHz frequency response\u003c\/li\u003e\n  \u003cli\u003e6.3mm headphone output\u003c\/li\u003e\n  \u003cli\u003ePair of driver tubes and pair of power tubes included\u003c\/li\u003e\n  \u003cli\u003eCompact desktop chassis with wood side panels\u003c\/li\u003e\n  \u003cli\u003eHandcrafted in Poland\u003c\/li\u003e\n  \u003cli\u003eSimple, focused design with no unnecessary extras\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eTechnical Specs\u003c\/h3\u003e\n\u003ctable style=\"width:100%;

This is a system that enables more natural channel separation and wider soundstage by moving a part of the lower frequency range to the opposite channel.

Based on the flagship Envy platform, this Class-A, single-ended, transformer-coupled tube amplifier was developed around one of the most celebrated pairings in high-end headphone audio: Feliks Envy and the HIFIMAN Susvara.\u003c\/p\u003e\n\n\u003cp\u003eThe original Envy was already known for its ability to bring power, scale, tone, and refinement to summit-fi headphone systems. The Susvara Edition pushes that formula further with up to 9 watts of output power, new gain settings, premium Stradi S300B power tubes, amorphous-core output transformers, and upgraded signal-critical components inspired by Feliks Audio’s 25th Anniversary Edition. The result is an amplifier built not only for Susvara, but for any headphone that needs serious drive, control, and musical authority.\u003c\/p\u003e\n\n\u003ch3\u003eDesigned for Susvara, Built for Any Demanding Headphone\u003c\/h3\u003e\n\u003cp\u003eThe HIFIMAN Susvara has a reputation for being one of the most demanding headphones ever made. It rewards amplifiers that can deliver real current, voltage swing, dynamic headroom, and control without flattening the character of the music. That is exactly where the Envy Susvara Edition is focused.\u003c\/p\u003e\n\n\u003cp\u003eFeliks Audio redesigned the gain structure with Low, High, and Susvara settings, with the dedicated Susvara mode delivering up to a 12% increase in power output compared to the Envy Performance. In practice, the Envy Susvara Edition outputs up to 9 watts of Class-A power, giving it the headroom to handle difficult planar magnetic headphones while still preserving the tone, dimensionality, and natural flow that make 300B tube amplifiers special.\u003c\/p\u003e\n\n\u003ch3\u003eMore Than a Power Upgrade\u003c\/h3\u003e\n\u003cp\u003eThe Envy Susvara Edition is not simply a louder Envy. Feliks Audio brought it closer to the technical level of the Envy 25th Anniversary Edition with upgraded output transformers, improved internal wiring, enhanced interference handling, and higher-grade signal components throughout the circuit.\u003c\/p\u003e\n\n\u003cp\u003eThat matters because high-end headphone amplification is not just about raw wattage. The best amplifiers control difficult headphones while preserving low-level detail, texture, dynamics, and spatial information. The Susvara Edition is designed to deliver that combination: more authority when the music demands it, and more finesse when the recording calls for restraint.\u003c\/p\u003e\n\n\u003ch3\u003eAmorphous-Core Output Transformers\u003c\/h3\u003e\n\u003cp\u003eOne of the most important upgrades in the Envy Susvara Edition is the use of custom amorphous-core output transformers. These transformers are designed to provide ultra-low noise, strong dynamics, and extended frequency response, giving the amplifier the bandwidth and control expected from a true endgame headphone amp.\u003c\/p\u003e\n\n\u003cp\u003eFor listeners, that translates into more effortless swings in volume, a quieter background, stronger bass grip, and a more open sense of space. It is the kind of upgrade that supports both technical performance and musical realism, especially with headphones capable of revealing every change upstream.\u003c\/p\u003e\n\n\u003ch3\u003ePremium Stradi S300B Tubes\u003c\/h3\u003e\n\u003cp\u003eThe Envy Susvara Edition comes equipped with carefully matched Stradi S300B power tubes, chosen for their precise, detailed, and airy presentation. A great 300B amplifier depends heavily on the quality of its tubes, and Feliks Audio includes a tube set that is ready for serious listening right out of the box.\u003c\/p\u003e\n\n\u003cp\u003eThe amplifier is also compatible with standard 300B power tubes using a 5V filament voltage, giving listeners room to shape the sound over time through tube rolling. That means the Susvara Edition can serve as both an endgame amplifier out of the box and a long-term platform for listeners who enjoy fine-tuning their system.\u003c\/p\u003e\n\n\u003ch3\u003eSignal-Critical Component Upgrades\u003c\/h3\u003e\n\u003cp\u003eBeyond the tubes and transformers, Feliks Audio upgraded several signal-critical parts of the Envy Susvara Edition, including capacitors, resistors, and internal wiring. High-precision components from brands such as Jantzen, Vishay, Nichicon, and Dale are used to improve signal clarity, repeatability, and overall circuit performance.\u003c\/p\u003e\n\n\u003cp\u003eFeliks also made additional refinements to tube parameter stabilization, tube-related failure protection, and the preamp output stage. The preamp section has been modified to reduce noise and better handle higher signal levels, making the Envy Susvara Edition a stronger centerpiece for both headphone and two-channel systems.\u003c\/p\u003e\n\n\u003ch3\u003eHandcrafted in Poland\u003c\/h3\u003e\n\u003cp\u003eThe Envy Susvara Edition is handcrafted by Feliks Audio in Lubliniec, Poland, with the kind of build quality expected from the brand’s flagship line.

Its Single-Ended Push-Pull circuit, eight-tube complement, substantial shielded transformer, and dedicated low-noise power regulation give the GA-10 the control needed for large-scale music while preserving the dimensionality and tonal character listeners look for from a tube design.\u003c\/p\u003e\n\u003cp\u003eHIFIMAN positions the GA-10 as a natural match for headphones such as the Susvara Unveiled and HE1000 Unveiled, but its three headphone outputs make it useful across a wider range of systems. Four-pin XLR and 4.4mm balanced connections sit alongside a 6.35mm single-ended output with impedance matching, giving owners flexibility when moving between different headphones and cable configurations.\u003c\/p\u003e\n\u003ch3\u003eSingle-Ended Push-Pull Tube Architecture\u003c\/h3\u003e\n\u003cp\u003eThe GA-10 uses a SEPP, or Single-Ended Push-Pull, circuit built around four ECC83\/12AX7 tubes and four EL84 output tubes. This architecture is designed to combine the tonal richness and spatial depth of vacuum tubes with the control required to keep complex recordings organized.\u003c\/p\u003e\n\u003cp\u003eLarge orchestral passages, layered rock arrangements, and recordings with wide changes in level place significant demands on an amplifier. The GA-10 is engineered to retain separation and composure through those passages, allowing individual instruments to remain distinct while preserving the scale and momentum of the performance.\u003c\/p\u003e\n\u003ch3\u003eEight Carefully Selected Vacuum Tubes\u003c\/h3\u003e\n\u003cp\u003eFour ECC83\/12AX7 tubes handle the voltage-amplification stages, while four EL84 tubes provide the output section. Both tube types have a long history in high-quality audio circuits and remain widely available, giving the GA-10 a familiar foundation for long-term ownership and future tube replacement.\u003c\/p\u003e\n\u003cp\u003eThe tube complement supports a presentation built around clarity, texture, and natural decay. Vocals and acoustic instruments retain body, while the amplifier’s low-noise design helps quieter details emerge without being obscured by hum or background interference.\u003c\/p\u003e\n\u003ch3\u003eShielded 120W Transformer\u003c\/h3\u003e\n\u003cp\u003eA specially selected 120W shielded transformer provides the GA-10 with a substantial power foundation. Shielding helps limit electromagnetic interference from reaching the sensitive audio circuitry, while the transformer’s capacity supports stable operation during demanding musical peaks.\u003c\/p\u003e\n\u003cp\u003eThe amplifier is rated to deliver 3000mW into 300 ohms and 600mW into 32 ohms at 1kHz. Those figures are supported by a circuit designed around control and clean power delivery rather than headline output alone.\u003c\/p\u003e\n\u003ch3\u003eIndependent Low-Noise Power Regulation\u003c\/h3\u003e\n\u003cp\u003eThe left and right channels use independent low-noise voltage-amplifier and stage-regulator circuits. A dedicated low-noise negative-voltage regulator further supports stable operation throughout the amplifier.\u003c\/p\u003e\n\u003cp\u003eSeparating and regulating these stages helps reduce unwanted interaction between channels and limits power-supply noise from entering the audio path.
