CJ ET3SE vs ATC-1 or ET5 vs ATC-2

So I have a Conrad Johnson PR140, rebuilt by CJ usilizing KT 120 tubes. I have Sonus Faber Luito 3 way floor standing speakers. Decent enough cables. I need a preamp. Bouncing between the Airtight and the Conrad Johnson. Not only bouncing on the entry level, but the step above taking me from the $4000 range to the $8000. Well, whick is the better pre, and do I need to step up to the middle of the road products or will the entry level work wonders. Thanks
