My understanding is that Lampi wanted something to compete with the ultra-detail boys, and so developed the PAC. It's somewhat inevitable that a more detailed DAC will sound "lighter / leaner / thinner". In some systems this isn't an issue and the PAC will sound a significant improvement on the GG2. If other components in the system are on the leaner side, the PAC may tip it over the edge and the GG2 will be preferred.
I've heard it both ways; in my original system of Berning Quadrature amps, I compared GG2 to PAC and preferred the GG2, as did others who heard the comparison. With the Stern / Heisenberg however, the PAC is a meaningful improvement, hence my upgrade.
