Tough call really because the two go hand in hand to create the sound you want. If you know you will eventually upgrade both, I would decide based on an anticipated pairing of the two - or at least an approach (class A, 300B tubed, Manley house sound, electrostats, whatever). You may need to buy separately for financial reasons, but I would have a goal of a sound you want first.
I listened to a lot of pairings and found a pair of speakers that I liked with multiple amps, so I did those first and it allowed me to consider multiple options. Other people may find an amp that gives them a warm fuzzy with many speaker pairings.
Good luck.
