Vanieri Audio Labs, a fresh face in high-end audio from Chicago, is poised to steal the spotlight at AXPONA 2025 with the debut of Varieta (VER’-ee-eh-ta, Italian for “variety”). Priced at $7,499, this groundbreaking preamplifier is the first universal Direct-Heated Triode (DHT) design, offering audiophiles the freedom to swap between over a dozen 4-pin medium-base tube types—think 300B, 801A, 45, 10Y, and beyond—with a simple dial twist. Set to premiere in Room 715 from April 11-13, Varieta redefines tube rolling, letting listeners sculpt their sound as effortlessly as a musician tunes an instrument or a connoisseur selects the perfect glass for a fine bourbon.

A New Era of Sonic Flexibility

Traditional preamplifiers tether users to a fixed sonic profile, but Varieta breaks that mold. By placing DHTs—renowned for their lush timbre and expansive soundstage—upstream in the signal chain, it liberates audiophiles from the power limitations of output-stage tube designs. The result? Unmatched versatility to tailor your system’s character to suit your mood, music, or evolving setup.

“I designed Varieta to fill a void I felt as an audiophile,” says Paul Ranieri, Owner & Chief Engineer of Ranieri Audio Labs. “DHTs have long been prized for their natural sound, but their use in final amplification restricted speaker options. By reimagining them in a preamplifier, I’ve removed those constraints and unlocked a playground of tonal possibilities. Each tube—whether it’s the 300B’s warmth, the 801A’s detail, or the 45’s dynamics—brings something unique. Varieta lets you explore them all in one beautifully engineered package.”

Varieta: Crafted for the Connoisseur

The world’s only universal DHT preamplifier, Varieta supports an array of iconic 4-pin tubes with instant optimization via a selector dial—no soldering or guesswork required. Its dual-mono, zero-feedback architecture, paired with custom transformer-coupled outputs and premium components, delivers crystalline clarity, rich warmth, and immersive depth. Encased in aircraft-grade aluminum with a sleek black or silver anodized finish, Varieta is a visual understated masterpiece that lets its sound take center stage.

Hear It First at AXPONA 2025

Audiophiles can experience Varieta’s game-changing debut in Room 715 at AXPONA 2025, held at the Schaumburg Convention Center. This is more than a product launch—it’s a redefinition of what a preamplifier can be. Visit Ranieri Audio Labs to discover how Varieta turns tube rolling into an art form, offering a bespoke listening experience that’s as dynamic as your passion for sound.

Publisher

Marco Lisi is the publisher of Best of High End, part of AV Concepts BV. His path into audio started early: as a teenager he was drawn into the world of free radio, presenting shows and living immersed in music every day. In his early twenties he ran his own production studio for five years, creating jingles and commercials — hands-on training in sound design, pro-audio workflows, and critical listening through studio monitors that still shapes how he evaluates gear today. He also spent years DJing in clubs before moving into publishing, first at two earlier online magazines before founding Best of High End. His hi-fi and home cinema passion was inherited from his father, an inveterate system-swapper. Marco's first setup — a confirmation gift — paired AKAI separates with entry-level Bowers & Wilkins speakers, a brand he stayed loyal to for years as his system grew from stereo into full surround and home cinema. Like many enthusiasts, he went through an extended "audiophile" phase chasing the next upgrade, before settling into a more grounded view: gear as a means to enjoy music and film, not an end in itself. Years of critical listening have given him a well-trained ear — the ability to characterize a system or pinpoint a change in the chain quickly and accurately. Just as important, his teaching background (a Belgian "regent" degree in Dutch language) gives him the tools to translate those listening impressions into clear, readable writing.
