### Clue: As discs they are unsurpassed (7)
### Answer: RECORDS 
 ### Explanation: Definition: they are unsurpassed
  Cryptic defn: Results of competitive events that are unsurpassed – for the time being, at least.  And gramophone records are also shellac and later vinyl discs that were once THE medium for sound reproduction.  I suppose I could also call this a double defn. clue, but I thought a better construction for a double defn. would have been "They are unsurpassed discs."
