The Lomenzo is the best drive (for me) that I've found. I have a few issues with it: the form factor, the useless VU meter and the overabundance of controls... and being of a diy bent I've always fancied tackling a redesign of it but "real life" keeps getting in the way...
I like it on its own for what I do, but you're not alone in liking to stack it! I've seen that a few times - Peter Iwers, formerly of In Flames, stacked it with an MXR DI.
