I have not used the "Broadcast" model so I can't offer any personal experience on that, however I do own (and use daily) the Fethead and Fethead Phantom. Both are absolutely flawless in operation: dead quiet, low-noise, and they've greatly improved my signal chain for voice-overs and screencasting. I'm sorry you had a negative experience, perhaps it was a faulty unit. Did you contact Triton about your concerns? My hunch is you got a dud or something; because my Fetheads added between 18-20db of super clean gain on both dynamics and condensers. Noise was non-existent. On the other hand, the one time I used a CloudLifter in a pinch at a gig though, I did notice a rather large boost in noise. So for me, Fetheads were the obvious best choice. I seriously cannot recommend them enough. You should try the models I mentioned before giving up on Triton, imo...
I think you misunderstood what this product is for? It's intended for super long cable runs up to 3000 meters. the idea is that it boosts the signal before the cable run so that the signal you want doesn't dissipate over such a long run. I am assuming that you performed your test in a studio environment with a standard xlr cable which would explain the extra noise added.
The broadcast version is a problem solver on location. The noise added is not an issue as I use it to get rid of hums and buzzes. (adding the gain on the microphone side means less gain at the truck side and thus less added noise that is picked up buy the cable) For noisefree amplification there are other Triton products. Huub
