Hands on with the IGS NE573
By Front End Audio on Aug 8th 2019
It's no secret that IGS makes some fantastic clones, and furthermore – brings most of those clones to the 500 series format. IGS' latest offer, the NE573, continues that well respected constant from them. Of course, it doesn't take much to figure out from the model that this is a 500 series clone of the classic Neve 1073 preamp. Being fans of that classic British sound, and what IGS consistently does so well, we couldn't wait to get our hands on one of them. So we bought one for the shop. As soon as it came in, we dropped it into our API lunchbox, and broke out the mics and acoustic guitars.
So what is hands on with the IGS NE573 like?
First off, the module is heavy. It is build strong, all knobs and buttons are solid, detents and steps are chunky, and it is loaded with Carnhill input and output transformers. Right off the bat, you know that IGS (in typical fashion) cut no corners, and put a lot into this preamp. Being that Carnhill came out of St Ives (when St Ives closed up shop), and that St Ives Transformers are what were used in the 1073s, going with Carnhill is 100% the right move. That is the closest you are going to get to the originals. Not only did IGS set out to build a solid unit physically, they set out to create an authentic sound.
When we get to performance, the NE573 continues to impress. Of course a 1073 always pairs nicely with a U67, so we set up an ADK T-FET67 and tuned up the Taylor (this preamp also gets along very well with the Peluso 22 251). With acoustic guitar, vocals, and the two together, the results were smile inducing. There was a smooth richness to the overall sound, detailed (but slightly softened, or rounded) upper mids and transients, a present but natural and controlled bottom (so not boominess at all), and a massive weight in the mids and low mids. The fullness and woodiness it brought to the body of the acoustic, and the foundation it laid for a vocal was huge. Add a soft top and an overall dimensional sound, plus a hot output with super low self-noise (this preamp is dead quiet), you can have nothing but love for the NE573.
We always have high expectations for IGS products, and the NE573 did not disappoint. Whether on guitars (miked or DI'ed) – acoustic or electric, vocals, drums, it really doesn't matter the sound source. If you want a fat dimensional vintage sound, with plenty of transformer richness and modern no noise cleanliness; to add depth, punch, and an overall classic warm tone.............. You know, let's simplify that. If you want an amazingly solid and impressively authentic 1073 clone – get the IGS NE573.
