Parasound Zphono USB Phono Pre Amp/Digital Interface

I'm getting rid of old and deadstock equipment. So, feel free to make me an offer!
Also, I'm still trying to figure out the shipping calculator here, so if you're interested let me know if you want a more accurate shipping cost estimate.

This is a Zphono•USB Phono Pre-Amplifier & Digital Interface by Parasound. The legendary San Francisco-based hi-fi manufacturer Parasound designed this high-quality entry level pre-amplifier to sound excellent with a wide range of turntables and phono cartridges. This version of the very popular Zphono includes an internal ADC and USB output for vinyl enthusiasts interested in digitizing their collections. Comes with three-prong AC cable, USB cable, manual, and original box. 110/220V compatible.

Zphono•USB Phono Preamp & Digital Interface
Easily record your vinyl LP collection to MP3, FLAC or WAV files
The Parasound Zphono•USB is a high-quality phono preamplifier engineered for optimum vinyl LP playback quality. The Zphono•USB has precise RIAA equalization and uses high quality parts to achieve extremely low levels of noise and distortion plus accurate frequency response.

In the digital realm, the Parasound Zphono•USB has an A-D converter and USB output to make high quality digital recordings of your vinyl LP collection a snap. Its unique front panel USB gain control and USB clipping indicator enable you to optimize the USB record output level to achieve a superior signal-to-noise ratio with most PC or Mac phono recording software.

If you have more sophisticated recording software, the rear-panel RIAA defeat switch allows you to defeat the internal hardware-based RIAA equalization in favor of software-based digital RIAA equalization. Two separate power transformers for analog and digital circuits assure the cleanest response and lowest noise.

The Parasound Zphono•USB has stereo input jacks for an MC or MM phonograph cartridge. A choice of MM-47 kΩ, MC-47 kΩ or MC-100Ω enables you to select the ideal gain and impedance for your cartridge.

The Zphono•USB includes two pairs of stereo line-level input jacks so you can also make digital recordings from other analog sources such as an AM/FM tuner, satellite radio or tape deck. A rumble filter switch and mono/stereo switch can further refine the quality of analog phono listening with older and mono LPs. A headphone jack is provided for easy recording monitoring.

- USB output to record vinyl collection to PC or Mac
- Front panel adjustable USB gain to maximize recording quality
- Front panel USB clip indicator
- Switchable rumble filter and stereo/mono setting

This item is in excellent used condition. I am the original owner, and I bought it in 2017 for use at home. I sent it back to Parasound in 2019 to get it back up to spec after I detected some channel imbalance, and now it sounds better than ever. The stereo output is excellent, and the ADC provided perfectly fine CD-quality output via USB (no drivers needed for Windows 10). I was and continue to be impressed with the performance and build-quality of this pre-amp, as well as with the customer service that Parasound has provided over the years. I am only selling because I upgraded to the Zphono XRM (also excellent). Will ship double boxed.
