My graph:
Our graphs do not match well. We have a situation here
The E5000 was measured with Type E ear tips, from Apple dongle. I did rerun the test with Fiio KA3 on high gain, but the FR is exactly the same, so I used the Apple dongle result.
Legato was measured from FiiO K7.
Maybe fit, seal, or because of the M6U, or something, but I'm shocked that the E5000 did not kick as well as Legato when I A/B to answer the question this morning.
And here is the thing, one Reddit guy who bought the E5000 after reading my impressions came back and told me "where bass?" Unit variation? Because the guy drove E5000 with his Topping stack, if I remember correctly.
