You may want to do some reading; a lot of the Dialogue Premium separates are rated class A by Stereophile and on the buy list for The Absolute Sound and other recommended buy reviews.
Of the PL equipment I have owned, I have been pleased with the value.
Prologue PL3, PL5, PL2, PL7(s), PL8.
My Primary system is Merlin / Filarmonia, which one of the sources is the PL8 CDP. I have sold everything else but the PL3 and PL5 (shelfed for now).
Next system will most likely include the PL HP and Dialogue Premium Pre.
If you wait, you will eventually find a Dialogue Premium Pre on the used market. If the price is reasonable, they sell in short time.
If your looking for solid state you may want to research the
The Odyssey Audio Khartago or Stratos. The online reviews may help you find a pre that works well. Also the above used Dialogue 3 may be a good fit, but I haven't done the research to determine if that is a fact.
http://www.odysseyaudio.com/Weinhart Design sells both the B&W and the PL equipment. He / They may be able to provide some info, of course keep in mind, they are a retailer. He should be helpful with things like describing the differences between the Dialogue 3 and The Dialogue Premium Pre-amp

Although I have concluded (for myself) that the PL equipment is a high value / sound quality equipment, I am not presenting the above referenced equipment as the absolute; there is a lot of good equipment being manufactured now days, and I am sure before too long you will be receiving many responses to your post and many of them good recommendations.
Good luck
