150W HiFi Stereo Integrated Amplifier

---

Howard Milstein - The Sound Advocate

"The Orchard Audio Starkrimson Amplifier evokes a Herculean form of Class D Amplification!"

and

"The power of the amplifier delivered a muscular sense of control over musical dynamics, (one of its biggest assets) and instrumental transients that undeniably confirmed that the Starkrimson had an abundance of reserve power..."

Ron Brenay - New Record Day (NRD)

"The amp sounded incredibly clean, and immediately sprang into action with powerful and confident-sounding bass."

and

"The separation of the information on top was really impressive and is one of the standout magic tricks of this amplifier"
