Know before you buy
The RP-7 v2 includes a high-power, tube-based headphone amplifier integrated directly into the unit. It is designed to drive a wide range of headphones with the same warmth and detail as the main preamplifier stage.
Yes, the unit features a dedicated home theater bypass. This allows you to pass signals from your surround sound processor through the RP-7 v2 to your main speakers, maintaining your high-end two-channel setup without needing to swap cables.
The RP-7 v2 uses four 12AU7/ECC82 tubes, which are common and easy to source. While these tubes have a long lifespan, you will eventually need to replace them to maintain optimal sound quality, a standard process for any high-performance tube gear.
The OLED display is fully defeatable. You can turn it off completely to eliminate any potential electrical noise or visual distraction during critical listening sessions.
Yes, the RP-7 v2 offers extensive connectivity, including both balanced XLR and single-ended RCA options. This flexibility allows you to integrate it into a variety of high-end audio chains.
The slow start turn-on sequencing gradually ramps up the voltage to the tubes when you power on the unit. This prevents thermal shock and extends the life of the tubes by avoiding the stress of an immediate, full-power surge.
