Lon beat me to the punch. I was going to say that, if your speakers are actually that efficient, they would likely sound excellent with the Taboo.
Also, in short lengths, I would concur with Lon's recommendation of the SonicWave optical cable, unless you can run coax, which I think is still preferable to optical. Much longer than 6 feet, especially if you have any bends, twists, turns, etc., you are taking a bit of a chance with bundled glass. I have liked the plastic optical I have gotten from Blue Jeans, finding them satisfactory even in comparison to the much more expensive Van den Hul. See
here. I use a 12-foot optical to feed from my AppleTv to a Dolby Digital decoder that then feeds to the Ultra preamp. Sounds quite good, but most of this is for casual listening or movie view off the ATV. But if I could use coax out of the ATV, I would still prefer that.
Gatornavy, just to put my money where my mouth is, I have an offer for you: if you buy a Taboo, I will gladly donate to you my ZSTAGE, which right now is sad and lonely in a cabinet. I loved it with the Taboo, but with the Ultra, have no need for it; it is all the preamp you will ever need, unless you have some need for switching capabilities. Anyway, your twelve years seem to me to merit it.
