AMS Neve 1073 DPX
The 1073 DPX is AMS Neve's modern, dual-channel take on the legendary 1073 preamp, packing two independent, genuine Neve 1073 transformer-coupled microphone preamp/EQ circuits into a single 2U 19-inch rack-mount enclosure. It has been available since July 2015. Each channel uses exclusive Neve Marinair transformers on the input and output stages, and the unit includes an external multi-voltage PSU. Beyond the classic 1073 feature set, the DPX adds modern conveniences: an integrated DI input, phantom power, a switchable insert path, level meters, and selectable headphone monitoring on each channel.
The EQ section is a three-band inductor-based design (fixed HF plus two switchable bands with cut/boost capability) along with a high pass filter. Alto Music lists the gain as +80dB to +20dB in 5dB steps, with input impedance of 10M Ohms (PAD off) and 10K Ohms (PAD on). The unit weighs in at 11.5 kg. Interestingly, one source notes that every frequency point was carefully selected by Rupert and his team of engineers — a nice touch of lineage to the original designer.
Reception among users has been positive, if occasionally qualified. One Thomann customer described the preamps as "smooth, solid, and confidence-inspiring," while a Gearspace forum post offered a more nuanced take: "The DPX is my favorite version of the 1073. With its newer design, it has a clearer top end while having good transients. The older 1073 have a little more character but it is a little cloudy. The DPX has the Neve color without the cloudy issue of the original ones."
That said, there are documented reliability concerns. A Gearspace thread titled "AMS Neve 1073 DPX fails when angled" describes a recurring issue, with one user reporting that a pair of DPX units developed failures, and that a subsequent pair of 1073LB 500-series units exhibited the same problem — suggesting a possible design flaw rather than a one-off defect. This is worth knowing if you're shopping for one used.
