Haha, I did the same thing already
But I found the Flares were definitely tuned with the Tx version.
If there is no wax guard, the sound is more harsh (5-10%?). It sounds more open, with cleaner highs, so somebody can say it is 'better', but then it goes away from reference signature.
I also noticed, the big L Complys (which I never used before - thought they are so big / was using only M), they actually can be inserted to my ear canal as well, but they provide much better seal, than smaller versions, once the foam spread itself through ear canal = better bass response with tighter body.
The Tx200 version provided with flares fits well, but when changing tips, I damaged already couple of Complys. Now I'm using Tx500, which fits also 100% secure, but you don't need to put them on/off with such hassle.
