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.

Acknowledging the importance of level matching when comparing source components is a sign of a good listener.

If you don’t understand the importance of level matching when comparing source components, you need a new hobby!
@jjss49 Yep…… surprised the snot out of them when i picked the Infinity Qb over the louder JBL -50.

and again with the Onkyo A-5 ( class A up to 5 watts ) vs a Nikko

and again with a Denon 790 over a Technics

and lastly the Grado over a Shure.

So while  Albert was pouring over whatever drivel Julian H was pushing, i was busy…listening..
