Differences PS Audio Trio P 200 and older GPC 200

Currently listening to PS Audio Trio P 200 and I hoping that someone may have compared with the older GPC 200.
Would you say that the older GPC 200 outperforms the newer Trio P 200 ?
I feel that the Trio P 200 is a serious bank for the buck, it may not sound as sweet in the top end as my tube preamps that cost 10 times more, allowing my planars to play deep and dynamic bass forcing me to turn off my subs.
I am not sure if the GPC 200 was replaced by the Trio P 200 ?

Thank you.
