In your price range I would suggest a used cj premier 17ls series I tubed pre-amp. I believe there is one being advertised on audiogon as I write this (no relationship). I had a 17 in my system prior to upgrading to a 16 series II and it was very musical and dynamic. It should be a good fit for you sonus faber grand pianos don't anything about the totem's.
