your speakers probably would be a tough load for the Almarro as Aball says but the Almarro sounds bigger than it's 18W per channel SET design looks on paper. the Cayin has nominally more power and both amps will sound very different from each other. If you have any way to audition each amp that would be optimum scenario. Speakers that are 89 db and 6 ohm nominal usually flourish with high current sand amps. Good luck in your hunt.
