Grade A - The best in the stock. Lowest noise and microphony with the tightest balanced sections we have available. This is typically 10% or often tighter given the large volumes of our stock.
 

Grade B - Low noise and microphonics with a section balance typically between 15% and 20%, but may be higher depending on available stock. 
 

Grade C - Lowest noise but slightly microphonic. Section balance will be similar to Grade A or B. This grade is only suitable for use in the driver stage of an amplifier, or the output/buffer stage of a DAC or CD Player.
