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.

I have no experience with the Nagra, but the Ray Samuels Nighthawk is a nice choice, better than the PS Audio GCPH IME.
In addition to size...what are your other constraints (like cost). I've heard that Nagra BPS, it's pretty nice. The Nagra VPS is better...and still might hit your size requirements...
How about the iphono by ifi audio, it's a sister company to AMR, looks like a pretty good product, the press on it has been spectacular.
