5534的声音确实不错,我在与TPA6120搭配的过程中,试过多种运放,例如,op627、op637、LM49710和LM4562等, ...
就violectric的输出运放问题,还写了邮件咨询,老外很认真地回答如下——
First of all, inside V100 the outputs are powered by a circuitry wit h4 transistors per channel.
NE5534 is only to control them.
Otherwise it would not be possible to have +/- 30 V supply !
For our opinion NE5534 is the best op-amp for this task.
If you dont share this opinion, feel free to plug in every other op-amp with the same pin-out and the ability of unity gain stability.
Be careful: Sometimes other op-amps tend of oscillate and may blow the power supply.
尽管如此,我还是把violectric v100内原配的5534ap换掉了,用opa604替换。5534听起来总是毛毛的。 |
