Vintage Volts Hi-Fi
Take vintage audio gear from inspection to evidence-based pricing and a Shopify draft.
Owner console prototype

The problem
Two vintage receivers with the same model number can command different prices. Condition, repairs, voltage, and whether the sale covers a single unit or a pair all matter.
Design decisions
I designed pricing around the actual unit and its condition. The console distinguishes completed sales from asking prices, shows the source listings, and keeps price and listing approval with the owner.
What it does
Equipment intake
Capture configuration, voltage, condition, repairs, accessories, and test results for the specific unit.
Comparable sales review
Open source listings, check whether the comparison fits, and keep asking prices separate from completed sales.
Three pricing positions
When enough suitable comparisons exist, compare quick-sale, balanced-market, and patient-collector prices.
Shopify draft approval
Review the equipment and price before creating a draft. The owner controls publication.
Storefront previews
Preview a listing as shoppers would see it, with private costs and internal notes kept out of the preview.

Screenshot tour
Record the gear
Record the exact model, voltage, and whether it’s sold singly or as a set. For this sample Pioneer SX-780, the owner records the channels and inputs tested, the cosmetic wear, and what’s unknown about its service history.

How AI helps
Find comparable gear faster
The prototype uses AI-assisted search to surface candidate listings for the model and configuration. The console checks which results qualify and calculates pricing options from the eligible comparisons.
Example
For a Pioneer SX-780 receiver, the owner can open the source listings and compare condition and service history before choosing a price.
What people decide
The owner approves the price and Shopify draft. The screenshots show simulated research. Live search in the owner console still needs verification.
