“After extensive use of your opamps on my JH428 (master section, 2 channels, control room/studio monitor and cue/echo path), my feeling is that I just bought a class-a console with extended frequency response, a much “fuller” sound and more headroom.
Tracking, mixing and monitoring now makes far more sense than before.
Even upgrading the master and monitor section alone makes sense.
Thanks again for giving life to my console with these opamps.
Keep up the good work.  My best regards,”
