## Which one to buy {#guidance-heading}

Our pick is the AD-1PA+, unless its features would be a dealbreaker; then the AD-2PRO+.

### Tonewinner AD-1PA+

Our pick. Choose it if:

- The AD-1PA+'s build matters more to you than the AD-2PRO+'s features.
- You would pay $476 over the AD-2PRO+ for the AD-1PA+'s 9.0 against 8.8 on the rubric.

### Tonewinner AD-2PRO+

Choose it instead if:

- The AD-2PRO+'s features matter more to you than the AD-1PA+'s build.
- Keeping $476 matters more to you than the AD-1PA+'s two-step lead over the AD-2PRO+, 9.0 against 8.8.

## Where they differ {#diff-heading}

Three topics the AD-1PA+ and AD-2PRO+ reviews both discuss, the most decisive first.

Only the AD-1PA+

- Amplifier
- Balanced

Only the AD-2PRO+

- Integrated Amplifier

### Power and system matching

The [AD-1PA+ review](https://theaudiostuff.com/reviews/tonewinner-ad-1pa-plus/#technical-specifications-100w-class-a-300w-ab) lists two strengths and one flaw here and the [AD-2PRO+ review](https://theaudiostuff.com/reviews/tonewinner-ad-2pro-plus/#technical-specifications-240w-and-dsd512) one strength, with no clear edge.

- AD-1PA+, strength: "1200W toroidal transformer + 180,000μF capacitance"
- AD-2PRO+, strength: "240W into 8Ω, handles speakers below 4Ω with ease"

### Features and formats

The [AD-2PRO+ review](https://theaudiostuff.com/reviews/tonewinner-ad-2pro-plus/#inputs-and-outputs-dac-phono-dual-speaker-sets) lists three strengths here, the [AD-1PA+ review](https://theaudiostuff.com/reviews/tonewinner-ad-1pa-plus/#technologies-switchable-class-aab-60a-on-tap) two strengths and two flaws.

- AD-2PRO+, strength: "Switchable Class A and Class A/B operation"
- AD-1PA+, flaw: "Class AB sounds drier and more clinical vs Class A"

### Build and controls

The [AD-1PA+ review](https://theaudiostuff.com/reviews/tonewinner-ad-1pa-plus/#design--build-quality-43kg-of-machined-intent) lists two strengths and one flaw here, the [AD-2PRO+ review](https://theaudiostuff.com/reviews/tonewinner-ad-2pro-plus/#build-quality-and-design-40kg-you-can-stand-on) one strength and one flaw.

- AD-1PA+, strength: "Massive 43kg overbuilt chassis with side heatsinks"
- AD-2PRO+, flaw: "Generates a lot of heat over time"

Only the [AD-1PA+ review](https://theaudiostuff.com/reviews/tonewinner-ad-1pa-plus/#technologies-switchable-class-aab-60a-on-tap) discusses circuit design (two strengths); only the [AD-2PRO+ review](https://theaudiostuff.com/reviews/tonewinner-ad-2pro-plus/) discusses soundstage (one strength, two flaws), connectivity (one strength), tonal balance (one strength), and measured noise (one flaw).
