Condition:New
Type:Logic ICs
Model Number:300B/2A3
There are two models of this machine, which are 2A3 push-pull, output power 12W * 2, and 300B push-pull, output power 20W * 2.
This machine is not a dual-use model, each can only use 2A3 or 300B. It is not possible to use two electron tubes at the same time.
This machine 2A3 push-pull standard comes with 4pcs 2A3SE type screen eggplant type electron tube.
This machine 300B push-pull standard comes with the sound of nobles HIFI series 4pcs 300B.
Not discussing the difference between push-pull and single-ended sound quality, this is inconclusive. Just like any ingredients, it depends on the skill of the chef. Anyone who decides that single-ended is better than push-pull or push-pull is better than single-ended is one-sided idea. There are few absolute things in the world.
As for the conclusion of the audition, first of all, although the power of the two models is different, they do not feel the difference in thrust, because the two tubes are low internal resistance tubes, with first-class control, and speakers as low as 83DB can be pushed. Then there is the sound quality. Based on my own tuning, this machine has the same charm as the single-ended machine. It is very sweet and charming, but the control and bursting power win.
