I have Unison Research S2 and they sound good. They have 10 watts per channels left and right. They have 4 Ohm, 8 Ohm and Zero Ohm for loud speakers wire.
 
I have not use it since I have a baby and I could not turn any sound from my loud speaker on.
 
That why I decided to get a head phone system. My headphone system are Yamaha CD S2000>  Burson AB 160 Buffer > Burson HA 160 D> HD 800, HE 500
 
Burson is good but it's far from the word sweet. It's warm and cool but it's not that sweet.
 
I like Burson sound but since I turned(very few times) Unison research with Mullard EL34, Bugle boy 12AU7 > Vienna Acoustic(Bach) It sounds very sweet and I missed it with my headphone system.
 
May I ask you guys. How can I use Unison research with 10 watts power as headphone amp. I did researching that I have to use jack transformer with dale resistor(something). I am an artist (painter, Sculpture) not a technical guy so I think I will find a shop to help me make this kit. 
 
Would anyone help me explain? It would be grateful for me.
 
Best

if you want add a headphone jack the answer can be found in the thread above i started earlier. it looks complicated for me so I never went ahead.
 
I suppose there are simpler options, like connecting directly to the speaker output terminals.
