    Rabbit Hole - Very Happy
    Stephen Lawson

    I have followed the white rabbit and I am in 500 series wonder land - I'll review 2 tubes (F609 and Retro 500 PRE) and 2 1073s (IGS NE573 and Golden Age PRE-573) 100% Honest when I placed my order for my first set of 4 500 series pres I did not realize I had two 1073 clones in my cart but the comparison be tween both is interesting. The IGS is solid feeling and has a nice weight to it everything about this unit says quality. The comb jack is a welcome add. The sound is extremely pleasing and little forward. I have used this on the Kick front and as a DI and both sounds have been winners. Very happy with this purchase.

    IGS NE573 500-Series Preamp
    Hank from Boston

    This unit does exactly what it's advertised to do. I have never used a real NEVE so I can't state how similar it sounds to one but it sounds fantastic. I recorded my RODE NTK that had been collecting dust the last few years and it sounded WAY more expensive. Great modern vocal sound.

What We Think

The IGS NE573 makes a statement the moment you pick it up — this thing is heavy. While installing it in the rack and putting it to work in the studio, it was immediately clear that IGS didn’t cut any corners here. The knobs and switches feel solid and deliberate, the stepped controls are satisfyingly chunky, and the whole module just feels built to last. Add in the Carnhill input and output transformers, and you know right away this preamp means business. Once we started tracking through it, the sonic goal became obvious: authenticity. The NE573 delivers that familiar, unmistakable tone we all associate with classic British console pres — rich, punchy, and musical, with weight and presence in all the right places. Knowing Carnhill’s lineage traces directly back to the St Ives transformers used in the original designs only reinforces what you hear coming back through the monitors. If you’re after a truly solid, no-compromise take on that classic sound in a 500-series format, the NE573 absolutely delivers. It looks the part, feels the part, and most importantly, sounds exactly how you want it to.
