### ⭐⭐⭐⭐⭐ Musicassette eccellenti!
*by F***E on 4 July 2025*

Musicassette a mio parere eccellenti. Sono arrivate ognuna protette da una scatola di cartone. Ho notato subito la qualità delle custodie che sono leggermente più spesse di altre in commercio. Il case è robusto è ben fatto chiuso da 5 viti per un eveltuale smontaggio. Nella parte bassa vi è un rinforzo di plastica nero come guida del nastro che impedisce vibrazioni nella lettura, accorgimento mai visto in altre cassette. Sto duplicando da vinile e il suono è ottimo in tutti i registri, non si nota una minima perdita forse un pochino solo nel registro acuto ma niente di eccessivo! Quello che mi ha colpito maggiormente è la qualità costruttiva. Sono molto soddisfatto e consiglio l`acquisto, restituiscono un suono pulito senza rumori di fondo, anche nel riavvolgimento rapido sono molto silenziose più di altre marche quotate. Che dire ne farò una scorta col tempo!
