Pros: Sleek design, quality finish
Cons: Either my L3 is faulty or the E9 jack ports are not a good fit.
I am struggling to discern any improvement in the SQ of my headphones HD598 and K702. They are amped by the just out of the box E7 & E9 respectively. Any o, improvement I will say improvement is only to boost the bass performance by a fraction (E7 on +1) and volume (E7 by 10%) by circa 20%.
I prefer the K702 & HD598 sound signature unamped (ie without the E7). Clarity is marginally compromised with a hint of hiss and color on E7 especially, but which has graciously rolled off highs. E9 provides a lot more power. Both enrich the bass for contemporary rock music, etc.
But then without much comparison (and I am fussy) I'd thought that both my cans already sounded really good.The biggest disappointment & dealbreaker however, is the poor connectivity at the line out dock. Increasingly so. Does anyone else share the same issue.?
