High End Design Since 1996


The Musica Bella Ibrido is a custom built to order hybrid amplifier. Utilizing the Seque single tube buffer stage, it provides a high input impedance of over 800K ohms which is feed by a balanced input transformer before feeding a  300/600 watt Class D amplifier module. The amplifier module is a custom OEM design by Class D Audio. The input stage is based on a single 6922/6DJ8 vacuum tube. The Seque input stage  smoothes out the edginess very often associated with this type of amplification. If you are looking for a sterile, dry "audiophilish" sound or a syrupy lush tube sound, the Ibrido is not for you.        SEE DETAILS
