My statement was: "A parallel resonant circuit is a high impedance (low
admittance)."

I reaffirm that statement. It assumes a high-quality circuit. It is
general and nonspecific. It is not all-inclusive. It allows exceptions.

In the ideal case, only perfect inductance and capacitance comprise the
circuit. Z = XL/R. As R goes to zero, Z goes to infinity.

The impedance of a parallel resonant circuit is:
Q(XL).
