All LJM products do not have circuit diagrams. Please don&x27;t buy if you mind.
All LJM power amplifiers are precisely measured by instruments, and the official sales version will be released after adjustment.
The following introduction will contain AP SYS 2 test data.
Due to the large amount of test data, only commonly used test materials are introduced.
If there are customers who need more accurate or special test data. You can consult with the owner individually.
Strictly measured by myself, the effect is completely preserved.
