Just put the finishing touches on Mentor serial number 002 today- the first production Mentor! The prototype L5 #001 was already a beast of a preamplifier, which I discussed a bit in my last post. As we moved into production, we made a few minor tweaks to even further enhance the sonics on this amp, including replacing the electrolytic power supply filter caps on the line board with a massive, extreme-quality Mundorf EVO film cap. Without any doubt, this amplifier can give any preamp in the world- at any cost- a run for its money.
