Integrated amplifiers — Nuprime Audio IDA-9

The IDA-9 is an integrated amplifier with a built-in DAC from NuPrime Audio, built with a compact chassis and substantial output. NuPrime Audio is a manufacturer with a serious reputation specifically for efficient class D amplifier technology, and the IDA-9 represents a compact, high-output expression of that broader engineering approach.

Position in line

It sits above the IDA-8 in NuPrime Audio's integrated amplifier hierarchy. This positioning above the IDA-8 suggests the IDA-9 offers more output or refinement than the brand's more accessible model.

Key specs that matter

One single-ended input is provided, a modest connectivity count. Phono MM/MC current-sensing input impedance is 200 ohms, an unusually low figure worth confirming directly given how it differs from typical phono loading standards. Output power is 250 W into 8 ohms, a substantial figure. Rated bandwidth is 10 Hz to 50 000 Hz. Distortion is 0.005%. At just 55 x 235 x 281 mm and 4 kg it is an exceptionally compact, light chassis for its considerable 250 W output, consistent with NuPrime Audio's characteristic efficient class D engineering.

Sound and use context

Expect a controlled, high-output presentation from a tiny, lightweight chassis - the exceptional power-to-size ratio here reflects NuPrime Audio's characteristic efficiency-focused class D engineering, delivering substantial output without the bulk a conventional linear amplifier of similar power would require.

Pairing

The single input limits this to a straightforward one-source system unless external switching is added, worth confirming this modest connectivity suits a specific system's needs before purchase.

Alternatives

NuPrime Audio's IDA-8 sits below this model in the brand's integrated amplifier range, worth considering instead if this model's already substantial 250 W output exceeds what a specific loudspeaker pairing requires. Given the unusually low 200 ohm phono impedance figure quoted here, a dealer conversation clarifying exactly what this specification means for cartridge compatibility is worthwhile before assuming a conventional MM or MC loading standard applies. NuPrime Audio characteristic focus on efficient class D engineering across its whole catalogue gives this compact model genuine credibility within that specific technological niche. A dealer visit remains the simplest way to compare current pricing between the IDA-9 and IDA-8.
