yea, I looked at the Bravo converter. I think leeperry has had it for a while now. I don't know all that much about it, and it seems like few people have it on this forum, so can't really advise for or against it. I've never listened to it.
Another option in that price range would be the M2Tech HiFace, which does usb to spdif conversion. I think there are some here on the Cables, tweaks, etc. FS forum, one may be a little cheaper than new. I have listened to the HiFace and it is a step up from some of the others I have owned and listened to.*
Maybe I can just rank the ones that I have owned.
#1. Halide Bridge(a wee bit out of your price range, but by far the best sounding yet, I think there is one her FS for ~$350)
#2. HiFace(you might find this one here for somewhere in the $120 to $130 shipped range, new for ~$160 for the RCA output one)
#3. Musiland 02 US(this is a good converter somewhere in the $100+ range, also has a headphone amp which you can compare to your Lite am dacs amp)
#4. Emu 0404usb(this one also has a headamp, and can do async conversion using ASIO drivers, but is VERY hard to get set up right, and takes a lot of fiddling around to work right, and I didn't care for the sound anyways)
Another one that I haven't tried yet but seems to get OK marks would be the Teralink X2 which looks to go for around $80 shipped. Possibly find it here for less used.
Basically what all these converters do, aside from the Teralink, is use a form of usb data transfer known as "async" which means the device that's plugged into the usb port is doing the timing control of the computer and telling it when to give audio data, as opposed to some other previous converters(and stuff made today even) that are known as "adaptive" that take the audio data as the computer gives it and try to time it as best as can be done. Aside from the technical aspects, I have to say that I enjoy async better than adaptive myself, just speaking from actual listening experience alone. You would think that just supplying the dac with ones and zeros would be enough to work, and it is, up to a certain point(apparently) and then the timing plays some part of the overall sound output.
I'm guessing you have a digital spdif coax or toslink cable to use with these.
*Although I didn't experience any problems at all when I owned a HiFace, others here have reported some problems with the output using certain media players. This device does use drivers that must be installed on your computer to work. I suggest some reading before making any hasty decisions, about any device, not just the HiFace. Aside from that, I think you might like it.
