Music Reference RM-4+ // Vintage / Tube MM Phono Preamplifier (604)

The Music Reference RM-4+ is one of those quietly brilliant vintage tube phono stages that punches way above its footprint—pure, minimalist analog engineering from Roger Modjeski with a sound that never tries to dazzle you with tricks, just music. Designed for MM cartridges, the RM-4+ uses a simple, elegant tube circuit that delivers everything we love about great phono design: a rich, dimensional midrange, sweet treble that never gets edgy, and bass that feels warm yet surprisingly articulate. It has that unmistakable tube glow—sonically and literally—bringing life, texture, and intimacy to vinyl in a way only well-voiced valves can.

Compact, honest, and deeply musical, the RM-4+ is a reminder of why Music Reference gear has such a dedicated following: nothing flashy, nothing unnecessary—just beautifully rendered analog truth.
