Dynamics
92/100
Reviewers explicitly praised the 14B³'s dynamic range and elevated clarity ('elevated clarity, dynamic range' and 'improved upon it with additional subtle sonic details'), and the amplifier's 600W/8Ω (900W/4Ω) ratings and very low THD (<0.005%) support strong headroom and current delivery. As a high-power dual-mono stereo amplifier this aligns with Class AB high-power expectations and the listening notes indicate authoritative, uncompressed delivery. No reviewer reported loss of control or clipping; the combination of spec and listening comments justify an excellent dynamics score.
Soundstage Imaging
90/100
The reviewer specifically mentions improved imaging and soundstage ('elevated clarity, dynamic range, and imaging'), and midrange weight/detail improvements on Vienna Acoustics speakers, indicating stable, well-defined imaging and stage depth. The amp's dual-mono architecture and strong channel separation implied by the review reinforce excellent spatial performance under normal loads.

Build Quality
93/100
Physical specs (91 lbs) and dual-mono design plus very low noise and THD suggest a substantial power supply and robust construction; the 'Dual-Mono' architecture (separate channel topology) earns an additional build-quality lift. Review commentary cites sonic improvements consistent with a high-quality power supply and componentry; no thermal or reliability concerns were raised. Overall the construction, heavy chassis and measured specs point to top-tier build for its class.
Value for Money
89/100
At $11,995 for a stereo, dual-mono amplifier delivering 600W/8Ω (900W/4Ω) with <0.005% THD, the 14B³ sits in the premium/high-performance segment. Reviewers did not explicitly compare peers, but the combination of class-leading power, measured performance and build quality compares favorably with other ~600W-per-channel premium amplifiers from established high-end makers (e.g., offerings from Pass Labs, Hegel, McIntosh in similar performance/price brackets). Given the strong performance described by reviewers and the heavy-duty specs, the price reads as a justified premium — not a bargain but defensible for buyers seeking high power, dual-mono construction and low noise/distortion.
