קדם מגבר Brama Preamplifier מבית VINNE ROSSI
סדרת המוצרים הנוכחית של Vinnie Rossi נקראת Brama, שמשמעות המילה באיטלקית היא ״תשוקה עזה״. הסדרה מהווה קפיצה נוספת מבחינת החברה, עם ביצועים ועיצוב ברמה הגבוהה ביותר.תכנון סדרת Brama נעשה בשיתוף פעולה עם המעצב התעשייתי הנודע, Olivier Raymond (מ-Porsche Design ו-Mercedes-Benz). המטרה הייתה להגיע לעיצוב על זמני, המגדיר מחדש את המשמעות של אלגנטיות.
