Accurate VTA adjustment for classical records is critical to their proper reproduction. If you do not have an arm that allows you to easily adjust its VTA, then you will just have to do it the hard way (which normally means loosening a set screw and moving the arm up and down until you get lucky with the right height).
Yes, it may be time consuming, it may even be a major pain in the ass, but there is no question in my mind that you will hear a dramatic improvement in the sound of your classical records once you have learned to precisely adjust the VTA for each and every one of them. We heard the improvement on this record, and do pretty much on all the classical LPs we play. All records really.
VTA is not a corner you should be cutting. Its careful adjustment is critical. Of course, so are anti-skate, azimuth and tracking weight. The links below have a fair amount of advice on turntable setup which might be worth checking out.
