AIYIMA T20 Balanced Tube Preamplifier
Taxes & Shipping Included
The Aiyima T20 is a fully balanced vacuum tube preamplifier designed to bring analog warmth and high-fidelity clarity to modern audio setups. Released as a premium milestone piece for Aiyima’s 10th anniversary, this compact unit pairs high-voltage PSVANE ECC83 tubes with swappable internal op-amps to bridge the gap between classic tube sweetness and modern, ultra-low-distortion transparency. With versatile XLR and RCA connectivity, a digital volume display, and convenient 12V trigger controls, it serves as an affordable yet highly customizable control center for audiophiles looking to elevate their desktop or home stereo systems.
The Aiyima T20 flips the script on what a budget tube preamp can do, serving up a fully balanced analog experience without the muddy, over-colored sound of yesteryear. Built to celebrate Aiyima’s 10th anniversary, this compact powerhouse pairs premium PSVANE ECC83 tubes with high-end, swappable internal op-amps to give you the perfect blend of holographic tube warmth and crisp, ultra-clean detail. Armed with true XLR and RCA routing, dual 12V triggers, and a handy remote, it’s a brilliant, highly customizable tweak-fest for any audiophile looking to inject some serious soul into their digital desktop stack.
The T20's amplification stage relies on two ECC83 tubes. These are combined with pre-amplification by LME49720 and OPA1612 chips, mounted to take full advantage of the character of the ECC83 tubes and provide them with a 180V signal. Furthermore, the T20 offers sound customisation through the use of interchangeable tubes such as 12AX7-S, 12AX7B, 7025 or 12AX7, depending on listening preferences.
The T20's aesthetic is both sober and elegant: a large, minimalist volume display makes it easy to read the settings, while the CNC-machined aluminium casing ensures a neat finish, good heat dissipation and a visually striking appearance.
