Product Highlights

This unit is fitted with a Sophia Electric Aqua 274B rectifier tube ($299 value) and includes vintage NOS tubes: (2x) Tung-Sol 6SN7GT parallel gray plate NOS tubes (1953, large "O" mouse-ear mica - $120 value) and (2x) Sylvania 6922 NOS tubes (1960s - $150 value).

The ModWright Analog Bridge with XLR upgrade features a pure tube stage with unity gain, output impedance below 20 ohms, 20Hz to 150kHz bandwidth, two RCA input and output pairs, and transformer-coupled balanced XLR connectivity using premium Lundahl transformers. Functioning as a high-fidelity line-level tube processor, this component inserts analog warmth, spatial depth, and harmonic weight into digital or solid-state audio chains. The power supply utilizes a 5AR4 tube rectifier alongside solid-state voltage regulation, feeding dual on-the-fly switchable output circuits built around 6SN7 and 6922 tube families. Exposed top-mounted sockets allow simple tube rolling, while the transformer XLR option provides pristine signal balance and ground isolation.

Critical consensus earned this component a Positive Feedback Brutus Award for its transformative effect on digital sources. Reviewers from Twittering Machines and Head-Fi praise its ability to eliminate digital glare and harshness without masking micro-detail or dynamic impact. Outlets highlight the flexibility of switching between the fast, transparent 6922 circuit and the rich, holographic presentation of the 6SN7 tubes.

Adding this device to your signal chain introduces natural warmth and three-dimensional presence to analytical systems. It resolves digital fatigue, letting you tailor system tonality to your exact preferences. For listeners seeking tube liquidity alongside balanced signal integrity, it delivers an ideal solution.
