What We Think
The Universal Audio 710 was already a contender in its price range the Revival mods make it a champion and irresistable at used prices.
According to Revival this unit has had a full audio path upgrade with the components tuned for more musicality, as well as better headroom, bandwidth, detail, frequency response, and signal to noise. The tube has also been replaced and the power supply redesigned. All amps have been replaced with Burr Brown High Performance amps.
Manufacturer's Description from UA
100% Tube to 100% Solid State — a Variable Tone Blending Mic Preamp & DI
The award-winning 710 Twin-Finity™ is a radically new UA mic preamp design that combines both the classic retro warmth of tubes with the transient bite of solid-state, all in a 2U, half-rack unit. The 710 was created specifically to add the tonal versatility and sonic inspiration missing from generic audio interface preamps. Tone blending is continually variable between 100% tube and 100% solid-state, offering a practically infinite range of unique preamp tones, plus the ability to easily dial-in your own signature sound. There are lots of sensibly priced solid-state and tube preamplifiers out there, but the 710 is the only one that offers the best of both worlds — as well as everything in-between — all in one box, and within reach of any serious project studio’s budget.
The key to its sonic flexibility lies in its innovative circuit design, featuring a solid-state transimpedance input amp simultaneously driving separate, phase-aligned tube and solid-state gain stages, which are then summed to a single output.. The mix between the 310 volt single-ended class-A triode tube stage and solid-state transimpedance stage is controlled via the "Blend Knob" labeled "∞". Blending is continually variable between 100% tube and 100% solid-state offering a practically infinite range of unique pre-amp tones and the ability to easily dial-in your own signature sound.
Like all our other preamp designs, the 710 features dual gain-stage controls (Gain/Level) which can radically vary the amount of coloration and distortion by allowing you to crank up the input gain like a guitar amp. The VU meter features a unique "Drive" mode allowing you to see how hard you are driving the input stage.
Versatility makes the 710 the perfect preamp partner for any mic collection. Plus, the discrete JFET DI input circuit can also easily handle any electric instrument. Guitar and bass players will especially appreciate the 710s ability to bring out the best of both active and passive pickups. The 710 Twin-Finity includes a 19" rack-kit for mounting one or two units.

About Manufacturer
Universal Audio Inc. was re-founded in 1999 by Bill's sons, James Putnam and Bill Putnam Jr., with two main goals: to faithfully reproduce classic analog recording equipment in the tradition of their father, and to design new digital recording tools with the sound and spirit of vintage analog technology. However, as Bill Jr. recounts, the genesis of "UA, part 2" is actually a bit more serendipitous.
Having grown up in the music industry, Bill Jr. and James ("Jim") Putnam naturally assumed that the music business is where they'd eventually end up. Jim, a touring musician and recording engineer, and their older brother Scott, a studio designer in Southern California, were the first to follow in Bill Sr.'s path. However, Bill Jr. took a more circuitous direction, working for a number of engineering companies before undertaking a doctorate in Electrical Engineering at Stanford University. It was at Stanford that Bill Jr. became closely involved in the Center for Computer Research in Music and Acoustics (CCRMA), specializing in signal processing. It was also at Stanford that Bill Jr. began to assemble a team of the best and brightest minds in the field — who continue to steer many of Universal Audio's engineering efforts to this day.
However, the precise event that led Bill and Jim to start (or "reinvent") Universal Audio in 1999 was unexpected. As Bill Jr. tells it, when Bill Sr. passed away in 1989, he and Jim were faced with the Herculean task of cleaning out their dad's workshop and storage areas. While going through Bill Sr.'s old test equipment, boxes of parts, bits and pieces of consoles, and half-cannibalized 1176 compressors, Jim came across their father’s old design notebook. The two spent the evening poring over his notes, realizing that this was the map to every technical problem their father had ever solved. It was at that moment that they decided to bring back Universal Audio and its classic products.
Fast forward a decade. Now with nearly 80 employees and legions of new customers worldwide, UA is headquartered near the Silicon Valley, in Scotts Valley, California — where our classic analog gear is still hand-built, one unit at a time. The lengths we go to deliver the exact sound and performance of classic analog audio gear is unparalleled; in fact, the goal is for UA's modern units to perform identically to well-maintained units built decades ago.
Of course, analog is only half the story. At Universal Audio, we employ the world's brightest DSP engineers and digital modeling authorities to develop our award-winning UAD Powered Plug-Ins platform, featuring the most authentic analog emulation plug-ins in the industry. Our DSP gurus work with the original hardware manufacturers — using their exact schematics, golden units, and experienced ears — to give UAD plug-ins warmth and harmonics in all the right places, just like analog.
