Some tube pre amps have 2 tubes while other tube pre amps have eigth or more. Can someone please explain why the difference in the number of tubes used in different brand pre amps. Thanks. Is there a significant sound difference between a pre amp with 2 tubes vs one with many more?
Some designers use more tubes in their designs. Some might use SS in the power supply and others might use a GZ34 rectifier tube. The difference in sound between different preamps is not necessarily related to the number of tubes used.
