Hi lewm;
Obviously I don’t know your system or the ART 7 but if I recall isn’t the ART 7 a very low output cartridge (.12mv) ? What gain is your stage set for while running the ART. I would suggest nothing lower than 66dB and perhaps as hi as 72dB (roughly a gain of 4000 times).
I'm sure you know all this but I’m humbly suggesting that if your cartridge is fully run in, it sounds like it could be loading or perhaps the VTA is too high.
The possibility of course exists that you have it perfectly setup and the sonic traits of the cartridge are simply not to your liking.
