What reviewers say
Sourced tester consensus for each — the "what people who used it think" layer, not just specs.
Triangle Borea BR03
Only one whitelisted tester, What Hi-Fi, published a hands-on review of this exact model (updated March 2025), awarding it five stars for sound. It praises a sophisticated, detailed presentation with big scale and agile bass, flagging only slight treble peakiness and fussy placement. No dedicated SoundGuys review exists; no lab measurements were published. (1 sourced review.)
Praised: Sophisticated, detailed sound with a big sense of scale; High-quality, agile bass with texture and weight; Excellent timing and careful tonal balance.
Flagged: Slight peakiness to the treble; avoid bright electronics; Fussy about placement; needs room from walls and some toe-in; Aesthetic won't be for everyone.
Kanto YU6
Only one whitelisted tester, SoundGuys, covers the YU6 — as the 'Best features' pick in its turntable-speaker roundup (score 8.8/10), not a full lab review, so no measurements exist. It praises the all-in-one connectivity (RCA, Bluetooth aptX/SBC, optical, ground/phono preamp, subwoofer out) and surprisingly thumpy 6-inch woofers, while noting the tuning isn't super neutral and bass-heads may want a subwoofer. (1 sourced review.)
Praised: All-in-one connectivity: RCA, Bluetooth aptX/SBC, optical, ground/phono preamp, subwoofer out; Surprisingly thumpy bass from the 6-inch woofers; Self-powered convenience with remote and basic EQ, no app or Wi-Fi needed.
Flagged: Frequency response is not super neutral/reference-flat; Bass-focused listeners may still want to add a subwoofer.
