Seems like one of Canary Audio's preamps would be a good match for your system, since you already have a Canary Audio amp. But there are so many good products out there, you really have a lot of options.I'm using a Bottlehead Foreplay preamp, and it is a pretty good amplifier. It's avaialble inexpensively as a DIY product, so you can build it yourself. They look pretty basic in stock trim, but some folks go all out on having a chassis made that makes their DIY efforts look world class. That's a pretty good way to go.
