What reviewers think
Bloggers and YouTubers have tried this product—so we've summarized their strongest opinions below. Links to full reviews follow.
Product Strengths
- Brushed aluminum housing gives the unit a sleek look
- An excellent buy for someone who owns ATH-M50, SRH-840, Koss Pro DJ-100, or AKG K701 headphones
- Adds a bright and intriguing level of sound to whatever is being listened to
- Delivers bang for the buck as a perfect entry level headphone amplifier
Product Considerations
- Stock Chinese tubes take quite a long time to burn in to get a really stable sound quality
- The DAC in this is middle-of-the-road
- There may be channel imbalance, more so in the left than in the right
- The included power brick is massive
- It is not going to power some of the higher end headphones
Comparisons (according to reviewers)
- Compared to Bravo Audio V2 amp, the EF-2A is a little bit better
- Compared to Parasound ZDAC, the EF-2A gives a warm, inviting tube sound
Takeaway: The EF2A is a great starter headphone amplifier, and a great product if one is looking to spend under $200 to make headphones sound a little bit better. The DAC makes it feel like two units in one.
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.

Reviews
Feliks Audio is a Polish brand that handcrafts tube amplifiers, including their flagship Envy model which features single-crystal copper wiring and 300B tubes known for their linearity and low distortion. Their amplifiers stand out for their ability to drive both high-impedance dynamic and planar magnetic headphones, which is uncommon among tube amplifiers, while maintaining a low noise floor and delivering natural, warm sound.

Product Strengths
- Unique and engaging musical experience, even with some hard-to-drive headphones
- Natural, fluid, musical sound with a bit of warmth, superb soundstage, and resolution
- Exceptional detail for the price category and low distortion
- Great build quality and a pleasing aesthetic, being hand-built
- Also works as a preamplifier for stereo setups
Product Considerations
- Not designed for planar magnetic headphones or for low impedance headphones
- May sound brighter, with lower bass quantity and precision, with low impedance headphones
- Tubes are consumables and will burn out after a couple thousand hours of use
- The power switch is located on the back, which some may find inconvenient
Comparisons (according to reviewers)
- Vs SPL Audio Phonitor 2 amp—Echo 2 provides a more refined experience
- Vs Hagerman Tuba—Echo 2 has better driving power and clarity for high impedance headphones
- Vs Audio-gd Master 19—Echo 2 has a more natural tonality and deeper soundstage for high impedance headphones
- Vs Violectric HPA V340—Echo 2 has a more magical musicality and a smoother presentation for high impedance headphones
- Vs Burson Soloist 3X Performance—Echo MKII leans towards a slightly more relaxed sound, while Soloist leans into a more forward aggressive one, and the Soloist has stronger treble extension
Takeaway: The Feliks Audio Echo 2/MKII is a great tube amplifier for those who appreciate engaging and emotionally rich listening sessions, especially with high-impedance dynamic headphones. This hand-built amplifier offers a unique musicality and adds warmth and depth to music.
