Another way to lower the VTA is to add a thin turntable mat to the one you already are using. A lot less trouble than the tonearm-based alternatives.
Also, you didn't say how much weight you added to your tonearm. The DL103 is both light and VERY stiff (compliance of 5). That's one reason the Zu103 works so much better--it adds about 10 g of effective mass to the equation. You need close to 30g effective mass to get the DL103 to hit optimum cartridge/arm resonance capability.
