Primare A35.2 Stereo Power Amplifier

Two hundred watts now, eight hundred if you buy a second one

The Primare A35.2 is a stereo power amplifier built on Primare's UFPD 2 Class D output stage, delivering 200W into 8Ω and doubling to 400W into 4Ω. Bridged to mono it produces 800W into 8Ω, so a pair can be run as monoblocks. An active power factor corrected supply keeps the current available when the music asks for it, and the whole thing weighs under 12kg.

Why You'll Love It

• It doubles into 4Ω. 200W into 8Ω becoming 400W into 4Ω is the sign of a supply that is not running out, which is what keeps bass tight on demanding speakers.
• Monoblocks are a later option. Bridge two A35.2 units and each delivers 800W into 8Ω, so the upgrade path does not involve selling what you already own.
• Quiet, and cool. Signal to noise better than 110dB with THD plus noise below 0.008%, from a Class D design that does not need a heatsink the size of the chassis.

Under the Hood

• UFPD 2 Class D output stage rated at 2 x 200W into 8Ω and 2 x 400W into 4Ω, or 800W into 8Ω bridged to mono.
• Active power factor corrected switch mode power supply, which draws current from the mains in phase and holds regulation under load.
• THD plus noise below 0.008% and signal to noise better than 110dB, with balanced XLR and unbalanced RCA inputs and 12V trigger switching.

CHT Insider Verdict

Class D has stopped being a compromise and the A35.2 is a good demonstration of why. It runs cool, it does not sag on dense material, and it will drive speakers that make traditional amplifiers of this size struggle. Pair it with a PRE35 over balanced cable. If you are already planning to bridge two, budget for that now rather than discovering the second one later at a different price.

Pro Tip: If your speakers dip below 4Ω anywhere in their impedance curve, this is the amplifier in the range that will not notice. Check the manufacturer's minimum impedance figure rather than the nominal one.
