MM Phono/RCA Input Flexibility: Serves as both a phono preamp and tube preamp, P7 is perfect for connecting turntables, phones, TVs, CD players etc. The P7 enhances sound clarity while adding a warm tone, bringing out every detail in your favorite music.
XLR Output for Pristine Audio: Besides standard RCA, the P7 features a true balanced XLR output, reducing noise and improving dynamic range. Perfect for amplifiers and active speakers, it delivers crystal-clear audio with a wider soundstage, ensuring distortion-free, immersive sound.

True Tube Amplification: Powered by brand-new PSVANE ECC83 tubes, easily swappable for tailored sound, the P7 brings warmth and sweetness to your audio. Driven at 180V, the tubes unlock the full potential of analog sound, offering a rich harmonic depth that audiophiles will appreciate.
Precise Tone Control with Bypass : Fine-tune the bass and treble for a customized sound profile, or engage the bypass mode for pure, unaltered audio. Whether you’re adjusting the tone or listening to the original signal, the P7 gives you full control over your listening experience.
Q&A
Q: What is the input voltage of the P7?
A: The P7 operates at DC 12V/≥2A. Using over voltage can cause damage, while insufficient current may affect normal operation.
Q: Can I connect a turntable directly to the P7?
A: Before connecting, please check if your turntable has a built-in phono preamp. If so, use the RCA input to avoid unwanted noise.
Q: Can the RCA and XLR outputs be used at the same time?
A: Yes, they output at the same time, with their volume and tone controlled simultaneously.
Q: Is the high-pass filter active in RCA input mode?
A: No. The high-pass filter is only available in phono input mode.
Q: Can I swap op-amps in the P7?
A: Yes, the P7 features 3 pluggable NE5532 op-amps, which can be replaced with other dual op-amps such as 2604, 2134, or MUSES02 etc. High voltage inside, please make sure the op-amp is properly installed before powering on.
Q: Can I replace the tubes in the P7?
A: Yes, the P7 supports swapping for PSVANE 12AX7-S, Shuguang 12AX7B, 7025, or 12AX7 tubes. Please replace tubes when powered off.

Common questions about buying open-box and refurbished.
Why buy refurbished or open-box?
Refurbished and open-box products offer the same performance as new at a fraction of the price. You're already saving $11 on this listing. They've been inspected, tested, and are ready to use — the only difference is the price tag. Buying refurbished also reduces electronic waste, extending product life cycles and keeping functional devices out of landfills.
What's the difference between open-box and refurbished?
Open-box products are customer returns that have been inspected and confirmed functional. They may show little to no use — often the item was returned simply because the buyer changed their mind. Refurbished products have been professionally repaired or restored by technicians, tested to meet or exceed manufacturer specifications, and sometimes come with a warranty. Both are a smart alternative to buying new.
Why use OpenBoxFox?
Finding refurbished deals is time-consuming — you'd have to check Amazon Warehouse, Reebelo, Dyson Outlet, and others separately for Douk Audio products. OpenBoxFox aggregates these listings in one place, so you can compare and find the best deal without the legwork. We update pricing daily so you always see current availability and real savings.
Is it safe to buy refurbished?
Yes. Products listed on OpenBoxFox come from established retailers like Amazon, Reebelo, and Dyson — not unknown third-party sellers. Each retailer has buyer protection policies, return windows, and in some cases warranties. You get the price advantage of used goods with the purchase security of a known retailer.
