“If we could measure a mic preamp’s cholesterol level, then this impressive super-boutique-vacuum-tube-animal from Chicago would be riding the edge of what is allowed in unsaturated fats! I have never experienced this much weight coming out of anything like the m63!  This is an unbelievable musicbox!! Big thanks to Flyline who imported this foreign dreamtool to Switzerland!”
