Bloom's Take Feliks Audio has a reputation for building OTL and Tube headphone amps that look great but sound even better. The entry point is the Echo MKII OTL tube amp at just over a grand which gives off cool vibes and sports a simple design. Its walnut trim would blend comfortably alongside vintage headphone gear, but would also fit aesthetically with modern systems. The warm glow of the tubes looks great when fired up as well. The Echo sports a 6.3mm jack and has decent power for a tube amp at 350mW. You get the inherent “tubey” sound you want but without sacrificing accuracy or transparency. We think the Echo MK2 is the perfect introduction to the Feliks line of crafted tube amps with its attention to detail and craftsmanship. However, if you’re more budget conscious and looking for an Endgame setup for headphones such as the Meze 109 Pro or Sennheiser HD 660S2, Echo MK2 won’t disappoint. |
Feliks Audio's Brilliant Entry-level Performer
The Echo MK II is an output transformer-less (OTL) headphone amplifier and preamplifier featuring stock Russian 6N6P and 6N1P tubes. Despite being Feliks’ entry-level amplifier, the Echo is no slouch when it comes to presenting a highly musical and well-extended sound. The Echo is slightly warm, smooth, intimate, and laid-back, flattering a wide range of headphones.
These qualities, in addition to incredible build quality and brilliant engineering, amount to an amplifier that performs far beyond its class. It is fully handmade, and the headphone sweet spot is for medium to high impedance headphones (from 100 Ω.) It can also be used as a tube preamp for both tube and solid-state amplifiers.
