Leben RS28CX preamplifierThe Leben RS 28CX is equipped with the CR type equaliser based on GE(General Electric USA) 12AT7 authorised by J. A. N.(Joint Army & Navy) standard of US Army, and can reproduce a very high quality and clear sound without adding any NFB. CR type equalisation requires a high gain level and is much more sensitive to tube quality. Since tube quality will be directly amplified, the finest possible quality tubes are needed for this type of equaliser.

I have purchased these for a few years directly from Whole Foods, and was excited to see that it was now available from Amazon. The quality has been changing recently. I have these on AutoShip and they’ve gotten increasingly darker in color which I’m assuming means cooked more or longer and they’re incredibly hard now. These are supposed to be a soft chew and I have a Chihuahua and even cutting them up, he can barely eat them. Hoping this feedback gets back to the right people in quality control.
