Appreciate recommendations for SS preamp purchase

If you already have Bryston gear, you can consider the BP-25 for probably slightly more than your $1K limit. I've never personally liked the Bryston sound, finding it a little too sterile, but many people do.

There are plenty of other choices, including the Marsh p2000b, McCormack ALD-1, Musical Fidelity A3cr or A3.2cr (the 3.2 has a little more clarity, the 3 a little more on the full and warm side, but I'm splitting hairs here), or Classe 5- or 6L. You might also find a Krell KRC-3 (cheesy-feeling volume knob but surprisingly good sound) for slightly more than your desired limit.

If you could elaborate more on how you would like to maneuver sonically and what your listening preferences are (and whether you intend to use balanced or single-ended connectors) it might help to nail down some specific recommendations.

So it sounds like your first priority is transparency.

I would try an Edge Si-1m or Musical Fidelity A3.2cr for your listening preferences (or, for a little more, the Musical Fidelity A308cr is a step up in that department). And the Bryston BP-25 is consistent with your goals, as well, and should mate well with your Bryston amp.
