My IE800 arrived a few hours ago.. done some preliminary listening (with the ODAC & Lake People G109-S)..
They definitely have that smooth, midcentric, romantic 'house sound' that's found on the BA200. Like the BA200's bass, the IE800's bass sounds quite linear to my ears. The BA200 had a bit more punch & impact (going off memory).. but the IE800's bass sounds tighter and faster. It's certainly punchy enough for my tastes, too. The BA200's mids were a bit more thick and dry in comparison to the IE800's airy, open mids. The IE800's mids possess that tinge of sexy warmthvthat made the BA200 so special.. it's just not laid on quite as much. The treble, more specifically the upper mids/lower treble, is where the greatest deviation between the BA200 & IE800 occur. The IE800 has more energy in this region.. giving the signature a greater sense of clarity & brilliance.. as well as giving the soundstage a sense of openness. I can't say that the IE800's treble is better or worse than the BA200.. moreso that it's different. What's most important to me is that both phones integrate the tuning in this area quite well with their overall sound. Despite the difference, I appreciate the treble tuning on both phones equally. Currently, the IE800's upper mids/lower treble are a little splashy and strident (even when being driven from a nice amp like the G109).. but we'll see if this smooths in time.
What I can say right now is that the IE800 is meeting, if not slightly exceeding expectations.. that's a very good thing. More thoughts coming later..
Nice initial first impressions, FlySweep buddy! I wholeheartedly agree with your assessment of the bass of both TDKs (I think the BA200's bass is more visceral), but both are just right. The punch/impact, tighter-faster is head on! Now, the treble will get much better with burn in. I was listening to some jazz the other night (I forget who it was) and the cymbal rides and splashes had some of the most natural sound and timbre that I've heard in most IEMs. Drum strokes have the right reverb and echo (beating out the GR07 for me once burn in sets in). Again, a longer silicon tip gives me the best details and timbre (like the R1's long double-flange). Anyway, happy listening!
