Rotel - RA-611 Solid state integrated amplifier

This like-new and well-functioning Rotel RA-611 amplifier is a true classic from the 1970s: a solid stereo integrated amplifier with the warm, characteristic sound of the Japanese Hi-Fi era. Thanks to its aluminum-shaped front and the original wooden enclosure, it also has an authentic vintage look — perfect for retro audio enthusiasts or as a focal point in a classic listening room.

With its combination of a neat build, versatile connection options (two phono inputs, multiple line/aux inputs, tape, tuner, etc.) and solid craftsmanship, this device is ideal for vinyl enthusiasts or for those who want to connect original vintage equipment to modern sources (via aux/tape). Thanks to the separated pre- and power-amplifier sections (pre-main-split), it is also flexibly usable in a more extensive audio system.

The RA-611 excels in accessibility: sliders for bass/treble and balance, input selection buttons and knobs, speaker A/B, tape monitoring, low/high filters, muting, loudness, and even a headphone jack. Anyone with an affinity for vinyl or classical Hi-Fi will appreciate the charm of this amplifier.
