Pre Amp Wars/Advice

I have posted another thread here regarding cartridge choices and had some very helpful tips. Ended up with a Benz silver on my Clear Audio Emotion table. As it fits my needs for now. Denon AVR receiver and B&W CDM9's.
But I am planning out my future purchases to build a system. All of which is going to consist of used equipment.
If I had the money to buy new. I would not be posting on a used equipment, for the most part, forum. But if there is something you folks think that can be purchased new that rivals my thoughts. By all means let me know.
My next consideration in my system is the preamp. This is going to built over time. One piece at a time.
Here's the list of preamps I am semi familiar with and one I owned.
Counterpoint SA5.1 I owned. Am familiar with the reliability issues. So no need to bring that up. Went back twice. Both times, the power supply was the issue. But loved the way it sounded. Associated equipment changed over the years. But Speakers used over time where. Maggie's and Apogee Duetta's. So that is my first consideration as I know it.
Second is a Counterpoint 3000 or 5000.
Third would be an Audio Research SP6 to SP9. Have never heard the 6 but have heard the 9 back in day on Martin Logan's.
So any thoughts are appreciated. If I missed something let me know.
By the way. Already in the process of upgrading the cartridge to a Glider S.
Gotta love this hobby.
Thanks for your input in advance.
