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.\u003c\/p\u003e\n\u003cp\u003eWe think the Echo MK2 is the perfect introduction to the Feliks line of crafted tube amps with its attention to detail and craftsmanship.

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.\u003c\/p\u003e\n\u003cp\u003eThese 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.)
