Rega P25 vs. Rega P5

I'm considering upgrading my TT. One of the brands I'm considering is Rega. One of the models I'm considering is the P5. But I'm wondering how the P25 would compare to the P5.

I've done extensive research on both. In considering the P25 over the P5, I've concluded the following:

1. The price of a P25 would be lower than the P5.
2. Since it's no longer made, the P25 would be older.
2. The P5 could be upgraded with the TT-PSU.

I'm hoping that there may be members that have had experience with both that can provide useful input regarding comparing the two. If it helps, in both cases, I am unimpressed with the base. So comments regarding the base of the P25 being better than the P5, although appreciated, would not be helpful.

I currently am using a Sansui direct drive. I'm upgrading the cartridge on the Sansui to a Denon DL-160. So, in the short term, if I purchased a Rega I would install the Denon Dl-160 after the purchase. However, eventually, I plan on upgrading the Denon cartidge to a Dynavector 10X5.

I can provide details on my system, but, as I'm asking for input regarding members' personal experience, I wasn't sure if this would be relevant.

Thank you in advance.
