RS-30EQ PHONO PREAMPLIFIER
- Positioning: A dedicated phono preamplifier with a CR-type equalizer focused on precise tone control.
- Description: Uses a high-quality Orient-Core power transformer and GE 12AT7A tubes to achieve a stable, low-noise equalization setup. Compared to other models, its simple design and lower power consumption make it a good choice for smaller rooms and budgets, with functionality tailored for accurate phono playback.
CS-300F PRE-MAIN AMPLIFIER
- Positioning: A compact tube pre-main amplifier designed for clear audio signal preparation.
- Description: Uses GE JAN-6197 and a premium Japanese 17EW8 driver tube to deliver clean amplification in a small, efficient unit. Relative to the RS-30EQ, it offers additional pre-main functionality while maintaining a straightforward tube sound, suiting users with modest space and budget constraints.
CS-600 PRE-MAIN AMPLIFIER
- Positioning: A versatile tube pre-main amplifier featuring dual tube options and extended controls.
- Description: Provides selectable output tubes (6L6GC or EL34) and multiple input options along with a power amp bypass to tailor the sound and impedance for various setups. Compared to the CS-300F, its extra functions and tube switching give users more flexibility and technical refinement.
CS-1000P STEREO POWER AMPLIFIER
- Positioning: A high-power tube stereo amplifier built for large audio systems.
- Description: Uses pentode circuit designs with KT120 tubes and a newly developed Orient-Core output transformer for wide frequency response and robust amplification. When compared to pre-main units like the CS-600, its advanced circuitry and higher power output accommodate larger rooms and higher-end setups.
RS-28CX PREMIUM PREAMPLIFIER
- Positioning: A flagship premium tube preamplifier aimed at achieving refined signal quality.
- Description: Features a CR-type equalizer with GE 12AT7 tubes, an independent power supply, and a dual triode 6CG7 SRPP design that ensures a clean, high-voltage output. In contrast to the CS-1000P, its superior build and technical sophistication address the needs of users with the highest performance demands.

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.
