It did raise the noise floor as those bipolar parts are .5 nv noise, the jfets are all 1 nv or more for the 40 volt parts. A very high input impedance is one benefit of the jfet frontend. Linear Systems 1 nv noise matched dual fets might be a great part to try.
Thank u for good review.
Are “Jfet” and “fet “ same ?!
And what is the other preamp product with this technology?!
