OP thanks for the added clarity and so cool about honoring memory with the Linn. I believe it can take you far. You have got a ton of good advice I understand wanting to make a positive and energizing change focused on vinyl.
pretty much all preamps listed, i have been fortunate to hear, owned a NOVA III. Super neutral fast, adaptable for growth into M should you climb that hill. The Chord i had in for evaluation as local dealer wanted evaluation of competiveness vs Nova ( he now carries both. For warmth and easy front ( top edge really ) panel adjustment, it edges Nova ( i think there is a newer Nova now ) Lean to wanting warm = chord, Analytical but neutral Nova. Sutherland leans that way. Parks is fascinating and i have heard it sing, kinda depends how analog you want to be, but if it was covered by shoebox, bet it could fool a LOT of diehard analog freaks…..
I just can’t comment on the Moon, have not heard it. Buddy did buy a Van Alstine, new it hits your budget. Frank builds great gear !,,,
best to you
Jim
