Is Nagra BPS The Best Small Phono Pre?

I have downsized considerably, from a ASR Basis Exclusive, and I'm ready to get a new phono stage. Is the BPS the best of the smallest? I wish I could afford the size of a full shelf but I can really only fit something a half shelf size and short height works well but I'd maybe be able to create some height is there was another good option. Turntable will be a Kuzma Stabi S/Stogi and Lyra Delos.
