This positioning below the brand's element-series flagships suggests the mini-i 4 offers capable core conversion technology at a considerably more accessible price than Matrix Audio's top-tier models.

Key specs that matter

Sound and use context

Pairing

The 4.4 V balanced output offers strong drive into a passive preamplifier or long cable run, a useful practical advantage for certain system configurations.

Alternatives
