Guy, At this point, there is no comparable alternative that we are recommending. For the record, the FireBox is an excellent choice for high quality SSB. It does have a limitation to 48kHz, but that was all we had until a few weeks ago anyways. I would still highly recommend the FireBox for those that are looking for high quality audio.
As always, we will be scouring the latest audio gear for other devices which may work well with our product. When we have another top notch performer, we'll post it here and on the website.
