Good sounding transformers are extremely difficult to manufacture. The sound or performance is relative to the frequency response, phase shift and distortion. Jensen is one of the only companies that actually publishes all of the specifications so that a serious circuit designer can make engineering decisions based on the true values, not merely posted specifications. Very few companies show their noise rejection (CMRR) which for all accounts, is the primary reason to incorporate a transformer into a circuit design or isolator into a PA, broadcast, hi-fi or recording system.
