Received singxer's SA-1 earphone (engineering prototype)
In fact, this earphone should have been received for a long time, but it's a pity that part of the output interface of the previous one is short circuited (possibly due to transportation) and sent back to replace it with another
According to the developers, this is "high performance, fully balanced, fully discrete class a earpiece / pre stage", but I said: there is a certain bragging element. Because according to the measurement, I can only believe that it may be class A under "normal headphone output power". Otherwise, it has several watts of output power. If the heat dissipation of this case is pure class A, then it will explode in situ
OK, make complaints about it.
Look at things
Because it is an engineering prototype whose appearance is not for reference, I do not provide evaluation on the appearance.
Less nonsense, more measurement
Balanced input and output no load:
Balance input and output 33 Ω load:
Very powerful performance!
Dynamic range:
多音:
Let's finish today
