Apparently the Tungsten runs well on the Cayin HA-3A and I was wondering which version would run best as the double sided driver version is more efficient than the single driver verison or do both versions run fine on this amp?
You will find the Tubgsten far out performs the LCD4 in resolution and other technical aspects.
And the double tungsten outperforms the single, though both are rather similar and I enjoyed both (small differences noted plenty in thread which I’m guessing your caught up with; so just a matter of taste beyond)
