Hi Mikeyc8: Ikeda's tonearms, like the FR's and IT's mostly veer in the direction of high mass, and should work far better with low-compliance cartridges than high-compliance. I'd say that the IT-245 is at least comparable the 64fx, and probably somewhat better. But you do lose the convenience of universal-type headshells. In a universal headshell tonearm, the IT-345 is a more sophisticated design than the 64fx and sounds better, but I don't think you will have much luck finding a second-hand one for sale (which is why I didn't mention it earlier).
>The Micro 505 is also interesting, as it has VTA on the fly I believe.
Note that the 505 was made in straight-tube as well as S-tube variants. I've owned the 505, and I'd say that it has a midrange-oriented, forgiving personality that is quite likeable. But in terms of frequency extension, dynamic range and resolution, it isn't as capable as the 64fx or IT-245. FWIW, FR made an on-the-fly VTA adjustment piece for the 64 and 66 family, which was called the "Arm Elevation Base".
Good luck with your search!
