The Vintech X73 Microphone Preamp & Equalizer is a class A, all discrete, transformer balanced microphone preamplifier with equalizer. It is built with the same circuit design and components as the classic Neve 1073 module. You won't be able to tell the sonic difference between a 1073 and an X73. The Vintech's are that good!

The Vintech X73 Microphone Preamp & Equalizer utilizes a Swiss made Elma input attenuator, custom dual concentric switches and potentiometers and custom machined aluminum knobs. By creating a custom wound set of input and output transformers, the Vintech X73 measures within tolerances that would be very acceptable to be considered "identical" to vintage Neve 1073 modules as measured through Rohde & Schwarz precision audio measurement equipment. If you're after perhaps the best, most faithful sounding recreation of the Class-A Neve 1073's magic, then look no further than the Vintech X73.

The Vintech X73 Microphone Preamp requires the Vintech X73 Power Supply Unit in order to operate. However, one of these power supplies will power up to FOUR Vintech units. By using a separate remote power supply, Vintech units maintain an extremely low noise specification.

What We Think


We got to know the Vintech X73 in early 2001 when a local Vintech rep brought a unit to Clinton Recording Studios for Eddie Kramer to evaluate the morning we began the stereo mixes for the Jimi Hendrix Experience 'Jimi Plays Berkeley' CD and DVD. Eddie wanted to hear the equalizer and so we patched the guitar to feed from the 8-track machine (we used the original 1-inch Scotch tapes) into both a channel on the Neve 8078 (31105 module) and into the Vintech X73. Despite the different Class A (Vintech) and Class AB (Neve 31105) topologies and differing equalizers, when set to similar frequencies and levels, they were still spot on; you couldn't tell the difference between the two. In fact, Jimi's guitar stayed patched through the X73 for the remainder of the album. So, that's what you're hearing. We have had the pleasure of using the various Vintech units throughout the years and have always been pleased with the results. We can certify that Vintech has done a fantastic job of bringing accurate Class-A Neve sound to us in a fashion far more convenient and cost-effective than the "spot-on" recreations... Though the Vintechs are certainly lookers, the beauty can be found inside, and in your ear-holes, thusly. If you've ever wanted bombastic drum tracks with beautiful, rich lows and nice smooth top-end, then Vintech's offerings are going to be your friend. Vocalists and their producers have always loved the 1073 for that rich lower-mid and smooth high-frequency treatment. Vintech has certainly captured this along with the transformer-sound characteristic of the Neve. The X73 and Vintech's variants (the X73i, 273, and 473) should be high on your list for building your dream studio.
