AIYIMA T20 Fully Balanced Tube Preamp — Swappable Tubes & Op-Amps, XLR/RCA I/O

Warmth, detail, and control in one compact preamp

The AIYIMA T20 is a Fully Balanced Tube Preamp designed for home audio enthusiasts who value nuance, texture, and dependable performance. Built around a 180V high-voltage tube core for premium ECC83/12AX7 tubes, it aims to deliver warmth, rich harmonics, and an expansive dynamic range that many low-voltage designs struggle to match.

Highly customizable sound

Take the tone in your own direction with a fully balanced signal path and swap both tubes and op-amps. The package includes both LME49720 and OPA1612 op-amps, so you can explore tonal flavors from vintage warmth to modern precision. The ability to swap components means you can tailor the preamp to your other gear and listening room.

• Fully balanced design reduces noise and maintains integrity through indulgent dynamics.
• ECC83/12AX7 tubes and swapable op-amps invite personal sonic shaping.

Professional-grade performance you can hear

The T20 emphasizes clean signal transmission with specifications that matter for fidelity: SNR ≥ 112 dB, THD+N ≤ 0.003%, and a dynamic range around 109 dB. Together, these figures support a quiet background and expressive peak handling, letting your music breathe.

• Low-noise performance supports delicate passages and micro-dynamics.
• High dynamic range preserves contrast between quiet and loud moments.

Intelligent control and seamless integration

A large digital volume display and a responsive remote place essential adjustment at your fingertips. The built-in 12 V trigger lets the preamp synchronize with power amplifiers for automated on/off behavior, simplifying setup in multi-component systems.

• Remote control for convenient listening sessions from your sofa.
• 12 V trigger enables automated start/stop with compatible amplifiers.

Premium build for real-world use

The T20 is housed in a solid, unibody aluminum chassis with a fine sandblasted finish. This hard-wearing construction provides EMI shielding and a sophisticated appearance that complements high-end racks.

• All-metal construction improves durability and shielding.
• 20-second intelligent soft-start warms materials gradually for a refined start.

Important setup notes: AIYIMA includes a dedicated 12 V DC power adapter. Using an alt supply or higher voltage may permanently damage the unit. The T20 is a preamp, not a phono stage, so a separate phono preamp is required if you need vinyl input. When paired with a suitable power amp, it serves as a preamp in two-channel stereo or a 2.1 theater arrangement, offering possibilities rather than guarantees for your Hi-Fi and home theater setup.
