Benchmark DAC1 vs CAL Sigma

I have an old CAL Sigma I in my system. I generally like the sound, it's musical & dynamic, however there's a bit of shrillness in the top end that I find off putting. I'm wondering how different a modern upsampling DAC such as the Benchmark DAC1 or a PS Audio Digital Link III would sound in my system? I'm a bit of a noob with external DACs so any input would be greatly appreciated.

Craig,

I also have a CAL DAC (an Alpha). I haven't heard the Benchmark but I can say that my Alpha sounded SO much better with Sylvania 5751 tubes. Have you tried a different tube in your Sigma? That might help to reduce your problem with it, as you "generally like the sound".

Thanks for the reply Michael. I haven't tried a different tube, but that's an excellent suggestion. Where do you buy your tubes?
