If I'm not mistaken, he referred to bass attenuation relative to Leo I, not that Leo II attenuates bass in general. I tested Leo 2 with LX last night, and my ears were still "bleeding" It's all a matter of a personal preference, especially if you are a basshead and enjoy LX tuning. With Leo 2, LX bass is tighter, more articulate, more focused, which to my ears gives it a little more power and control. For me personally, I preferred Ares II pair up with more decay in bass for a better blend in/transition into mids. But it's all a matter of a personal taste. There is NO right or wrong answer on this one
You are definitely right I was comparing Leo 1. I actually tried the combo with LA-1+Leo2 last night and I found out that actually it’s not hold back the bass it’s getting a tighter and better quality of bass. The LA-1’s bass is still there but I feel bass is deeper and tighter. BTW, thank you Effect Audio for super fast response for my Y splitter.
