The Universal Audio 710 Twin-Finity is a radically different UA preamp design which combines the classic retro warmth of UA tube design and the transient bite of solid-state in a 2U, half-rack, all-metal chassis. The UA 710 microphone preamp and DI was created specifically to add the tonal versatility and sonic inspiration missing from generic audio interface preamps.
The key to the UA Twin-Finity 710 preamp's sonic flexibility lies in its innovative circuit design. The unit's solid-state transimpedance input amp simultaneously drives 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. 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 Universal Audio preamp designs, the 710 Twin-Finity 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 is designed and built at UA headquarters in California, and includes a 19" rack-kit for mounting one or two units.

I found that the further toward the solid state side the faster and more accurate the transients and attack became. When driven hard I found the tube side to break up and distort quite nicely and musically. The ability to fine tune the ratio and blend on the fly is great for finding the perfect tone that you are looking for.
This preamp is an outstanding value for those musicians or studios on a budget as it provides the best of both worlds in a single package - and it does them both very well. (Posted on 7/19/2012)
