      Cup Diameter

      The Giardinelli Sym. T has a cup diameter of 25.80 mm compared to 25.00 mm on the Giardinelli 5D — a difference of +0.80 mm. A wider cup generally produces a fuller, darker tone but requires more air support.

      Cup Depth

      Both mouthpieces share a deep cup depth, so the sound character from depth alone will be very similar.

      Throat Diameter

      The Giardinelli Sym. T has a wider throat (6.40 mm vs 6.00 mm). A wider throat allows more air through, increasing volume and projection but reducing resistance.

      Which is better?

      Neither mouthpiece clearly dominates the other — the right choice depends on your embouchure, playing style, and the sound you're after. Try both if possible.
