I would definitely think about the 326s. If the REF 3 and 326s are close in price (relative that is).
Mark Levinson company (don't know if this was Mark Levinson the person or the new company after he sold it), made/makes excellent equipment.
As Ralph (Atma-Sphere) also said, there are some pre-amps at or better than the REF 3 for the price.
But, you can't go wrong with the REF 3, 380s or 326s.
