11/10: New - Unopened Factory Shipment
An item rated as "NEW" must come in its factory-sealed box. The item should not have been opened or used in any way. The seller should clearly indicate if any warranty is included and specify whether it is backed by the manufacturer. Some manufacturers only honor warranties if the product is purchased from an authorized dealer, and others may offer warranties only to the original owner, even if the box has never been opened. If no warranty details are provided, it’s essential for buyers to inquire with the seller for clarification.
-
Important Note: Items that have been opened for inspection or any other reason should NOT be listed as "NEW."
10/10: Mint - Essentially Never Used, Factory Fresh Appearance
The "Mint" grade is reserved for items that have been removed from their original packaging but have barely been used—typically less than a year since first use. These items should look like new without any visible blemishes, scratches, or discoloration from environmental exposure (e.g., oils from fingers, smoke, or household chemicals).
Key characteristics:
-
Electronics: No visible scratches, nicks, or blemishes; connectors and plating should appear like new.
-
Speakers: No signs of use, with perfectly intact grilles and flawless veneer.
-
Turntables: Covers should be free of dust, fingerprints, or swirls.
Items at this level are rare, as very few pre-owned or demo products meet this standard.
9/10: Excellent - Perfect Physical Condition, Light Use
An item in Excellent condition will show signs of light use but will be in pristine physical shape. It may have been used occasionally but remains in near-perfect condition.
Key characteristics:
-
Electronics: No visible scratches, but light dust may be present in crevices. Connectors may show slight use, but no discoloration.
-
Speakers: Perfect appearance on the front face, with minor indentations on the back or bottom that do not affect the veneer.
-
Turntables: Minor signs of use, like slight hazing on the cover or minor scratches on the headshell.
8/10: Very Good - Minor Flaw, Well-Maintained
A product rated 8/10 has been used but is still in great condition. It may have a few minor flaws that are noticeable only on closer inspection, such as small scratches on the top or sides.
Key characteristics:
-
Electronics: Minor scratches on the top plate or sides (max 1/2" long), no major wear on connectors.
-
Speakers: Slight discoloration along edges or minor scratches on the bottom.
-
Turntables: Light haziness on covers, but no visible scratches on the main surfaces.
