Acknowledging the importance of level matching when comparing source components is a sign of a good listener.+1 @tvad
If you don’t understand the importance of level matching when comparing source components, you need a new hobby!
What is a cost effective way to level match, for comparing different hifi components?
Over the next little while I am planning on trying out some new DACs in my stereo system, and I know that it is important to make sure that sound levels are carefully matched when comparing. So I would like to ask others here how they do this? I realize that these days we all have smartphones and can download apps to measure SPLs. Is this accurate enough for careful comparisons. I wouldn’t mind getting some ideas from others on how they do this, and what might be the best way.
