Marillyn Crispell CD is a nice addition to a jazz collection. Too bad I will never hear it on the Nagra Jazz. A nice looking amp; it's from Switzerland!!

Looks like a very nice component.  Nagra gear always makes my heart pump.  Great sounding too, going by the review.

I am confused.  The review indicates that the input is differential, but later goes on to say that an optional transformer is required for differential.  If the amplifier is configured to do balanced (differential), why do we need a transformer to utilze this?

"If I had wandered inside, I would have discovered a 12AX7 dual-triode tube, one per channel configured in differential topology..."

"The Jazz's suite of inputs consists of one pair balanced (if the optional input transformers are fitted, otherwise this input is single-ended)..."

Any explanation?
