The highest quality sampler made for a basic "wedgie" Amiga was the Aura, which could sample in 12-bit, but required a PCMCIA slot (and another port on the back). I think it worked with both A600 or A1200.
If the delfina has inputs, that would be able to sample at higher rates and at 16bit.
For big box amigas, a lot of people rave about the quality of the Repulse card for this. (I have a repulse, but i'm no professional audio bod, however, samples from it do sound very good indeed to my untrained ears :-D ).
Anyway, check out the
