This table also reflects the history of NuPrime’s amplifier development and shows how far we’ve come. Ten years ago, the IDA-8 won two Product of the Year awards and a Golden Ear award, while the ST-10 (known as the NuForce V4) also earned a Product of the Year award. Today, we’re launching the IDA-9, which is more affordable than the ST-10 yet significantly outperforms the IDA-8 — and even surpasses the ST-10.
