In 2005, she released her album "Piedra de Afilar". This album brought in newcomer, multi-instrumentalist David Snow as a co-producer with her longtime husband/producer Diego Verdaguer. This album shows Amanda to be looking ahead to a more modern sound without losing the polished productions and fabulous songs that made her famous. This album also contains a long-awaited duet between Miguel and Diego, "Siempre Fuimos Dos", penned by David Snow, Diego Verdaguer and Miguel, with lyrics by Anahi, who also wrote all the other lyrics in the album.
