The advantage of a fully differential preamp or amplifier is that distortion is canceled at every stage in the device. As a result fully differential products can be lower distortion for a given amount of gain. Noise can be lower too- and the effects of noise and distortion always compound from stage to stage. The more differential circuitry is used, theoretically the more transparent the preamp or amp will be as well.
Balanced outputs vs balanced design
Friends, I am looking for a balanced tube pre to mate with Halcro MC20. I have since learned that there are single ended designs with balanced outputs and fully balanced designs, like the BAT's. In a response to a thread below the author suggests that the "magic" happens in the amp and that the pre does not have to be fully balanced to benefit from the noise reduction qualitites. If so, is thre any inherent advantage to a fully balanced preanp? And more particularly for my purposes which would not run connects more than 10' from the amp. If there is no great advantage to a fully balanced pre, I can widen my search. As always, tell me about your favorite tube pres to run with this SS amp. Many thanks.
