Short answer: the Adam Audio T5V. It ranks #12 of 64 powered bookshelf speakers by sound quality at $239.99; the Onkyo GX-30ARC ranks #43 and costs $349, so there is not much of a tradeoff to weigh.
What the Adam Audio T5V offers: Better than the HS5 in terms of vocals detail and better low end. Watch for: Elevated, slightly uneven top end from the AMT tweeter, shared with Adam’s other T-series monitors - the rear treble trim only tilts the response rather than flattening it. Distortion, while better controlled than most speakers in this price range, isn’t reference quality.
What the Onkyo GX-30ARC offers: A compact powered pair with unusually complete connectivity: HDMI ARC, USB-C, optical, phono/line, aux and Bluetooth 5.3. Erin’s data predicts a 5.55 score with a subwoofer, low 0.091 on-axis roughness and useful 62Hz in-room extension. Watch for: The response rises about +0.48dB per octave and narrows vertically, while directivity-index consistency is a mediocre 3.84. Its 0.232 sound-power smoothness suggests some room-response unevenness, and low bass still benefits from a subwoofer.
Buy the Adam Audio T5V. It ranks higher for sound quality than the Onkyo GX-30ARC and costs less, so there is no real case for the other one.
