I liked L Ortofons, but they seem to fit deeper into my ear where I am sure my ear narrows, so the 'chamber' that the IEM radiates into is smaller. The L Ortofons are inbetween the L and M Spiral Dots (and all other brands, too).
For me the L JVC Spiral Dots fit great because they are soft but firm and fit a bit further out in my ear canal so the chamber is larger in my ear. To me the L Spiral Dots sound much better than L Ortofons.
Chamber = the acoustic space between the IEM eartip and the eardrum.
THX to lee730 for turning me on to JVC Spiral Dots
You, Sir, might actually have bigger ears than my elephant ones. Haha. L Spirals might be too large for me then. Might try the Ms. Expensive tips though. Ugh.
Thanks for the info. =]
