Also there is the ADVANCE PARIS PX1 preamp
Tad off topic, but I wish this one, and this brand, were a bit more discussed here. Seems like a great box, features-wise. For example, there is a low-pass for sub, and a high-pass rca out, which seems an ideal combination, but also a full signal rca out, as well as XLR out. Sadly it is not measured, which would be very useful considering some of the features like this one :
The PX-1's interactive menu offers you two modes of use, "Class A" mode or discrete mode. The "Class A" output is based on a circuit based on bipolar transistors only, in a "double cascode" type assembly offering performance in terms of distortion gradient close to a tube assembly, therefore very homogeneous and polarized in Class A, the "discrete" output is a stage based on a more classic typology based on a differential stage JFET input and bipolar current mirror with a polarized output in class AB, more prone to distortion in odd harmonics sometimes less appreciated "at the ear", but sometimes also felt as more defined.
But yeah, I can't be easy for Amir to get its hands on a preamp from a relatively small french brand..
