As a Taboo III / Omega Super 3E owner, I can say that IMO they are a near perfect match. I listen desktop, nearfield (3ft). I'm using a Philips 5R4GYS Rectifier and Russian 6n1p-ev / 6p15p-ev tubes. The Valve Art 274B tube that came with the amp wasn't bad at all, but I prefer the Philips. Steve thinks the Valve Art 274B is a 5u4G in disguise.
Edit: Some may wonder why buy the Taboo III for speakers when it's supposed to be a SOTA headphone amp. In my case I had purchased Steve's SE34I.3 "Rachael" SET, but it had a hum problem that Steve couldn't fix for me because he couldn't hear, on his test bench, what I heard at home. It was back and forth to Steve twice. It wasn't due to tubes or ground loops or anything else we could determine. So, being the great guy Steve D is, he suggested trying a Taboo III with a little foil shielding thrown in for good measure given my hum issues with the SE34I.3. The same type of shielding used in the ZP3 phono stage. The Taboo III is inherently quieter than the SE34I.3. When I got The Taboo III, on April Fool's Day no less, I plugged it in and it was dead silent - no hum. It sounds every bit as good as the SE34I.3, albeit with one less watt of power (4.5 vs 5.5). This, as MoNelly's post above notes, is one great speaker amp, too.
The Omega's are super fast (almost electrostatic fast) and revealing. To my ears, the frequency response is very even from about 50hz to 15Khz (highest top end I can hear theses days) - no nasty bumps or dips. Sound stage depth and width are very good to excellent and very much dependent on your front end and quality of recordings. Very revealing of poor to mediocre material. LPs sound absolutely beautiful. You will need a powered sub woofer if you like low bass or listen to music that has low frequency content. IMO, a sub helps round out the sound of the Super 3E or T. The level 3 finish (in my case Bubinga, an African rosewood variant) is to die for. Louis is a master craftsman and one outstanding fella. Apart from Steve D's lifetime warranty, not too many audio companies offer a 10 year warranty. Between Steve D. and Louis O., you have two of the greatest guys in high end audio.
I have a CSP+ on order and I'm also considering a ZP3 phono stage. I believe, and Steve seems to agree with me, that the CSP+ is needed to provide a little more voltage and "balls" to sound than you can get with a W4S DAC-2 (2.6v tops at Max output via RCA) alone.
Edit: I almost forgot. The Taboo III, as you know, has 4 headphone outputs (2 phono) and (2 XLR) mounted flat on the black top plate. This means dirt could clog these openings. I suggest you consider some plugs for all 4 openings when not in use. I ordered mine from Markertek.com and received them 2 days later. The covers are inexpensive and made of soft rubber. They are black in color and fit snugly. The "Phone" plugs I previously linked to don't work, they are too big for the phono jack holes. I removed the phone cover link. However, either of the two XLR covers work fine. I recommend the "NDF" XLR plug, it's a lot easier to use.
