Only the AD-2PRO+
Power and system matching
Here the AD-1PA+ review is the kinder of the two and the AD-2PRO+ review has reservations:
- AD-1PA+, praised: "16 Toshiba output transistors - 120A of current"
- AD-2PRO+, praised: "240W into 8Ω, handles speakers below 4Ω with ease"
Features and formats
Here the AD-2PRO+ review is the more positive of the two and the AD-1PA+ review has reservations:
- AD-2PRO+, praised: "Switchable Class A and Class A/B operation"
- AD-1PA+, criticized: "Class AB sounds drier and more clinical vs Class A"
Build and controls
Here the AD-1PA+ review is the kinder of the two and the AD-2PRO+ review has reservations:
- AD-1PA+, praised: "Massive 42kg overbuilt chassis with side heatsinks"
- AD-2PRO+, criticized: "Generates a lot of heat over time"
Only the AD-1PA+ review praises its circuit design; only the AD-2PRO+ review praises its connectivity and tonal balance but faults its measured noise and is mixed on its soundstage.
What they have in common
The AD-1PA+ is a power amplifier and the AD-2PRO+ an integrated amplifier, both from Tonewinner, and both have balanced XLR inputs, RCA inputs, switchable Class A and Class AB operation, and real heat output in use. The AD-1PA+ and the AD-2PRO+ are both criticized for their placement.
On paper
The AD-1PA+ ranks joint #1 and the AD-2PRO+ #3 of the 4 speaker amps & preamps reviewed here; on value the AD-1PA+ and the AD-2PRO+ both rate Steep. The AD-1PA+ and AD-2PRO+ spec sheets match on class (switchable Class A / Class AB).
The AD-1PA+ and AD-2PRO+ figures are the makers' own; IEC 60268-3 defines how they are measured.
| Spec | Tonewinner AD-1PA+ | Tonewinner AD-2PRO+ |
|---|---|---|
| Power output | 330 W (THD 1%, 1 kHz) into 8 Ω | 240 W (one channel driven) into 8 Ω |
| THD+N | ≤0.008% (1 kHz) | <0.05% at 1 kHz |
| SNR | ≥115 dB (A-weighted, unbalanced) / ≥108 dB (A-weighted, balanced) | >100 dB (A-weighted) |
| Frequency response | 10 Hz - 100 kHz (+1/−3 dB) | 15 Hz - 95 kHz |
| Inputs | Balanced XLR, RCA | USB-B, 2× Optical, Coaxial, RCA, Balanced XLR, MM/MC phono |
| Outputs | Dual A/B speaker binding posts | 2× speaker binding posts, Subwoofer out (RCA/XLR) |
| Weight | 42 kg | 35.9 kg |
