I did not write to Oknyo about this. I was just sort of suprised to not see 8 Ohms as one of the choices.
Ths 705 replaced my 703 that started having "startup" problems and I cannot remember if it had the 8 Ohm choice or not.
I have tried both settings and I cannot hear any difference in the sound. altho I would be the first to admit I know I have some holes in my hearing range so I may not be the best judge of that.
I figured it was not that big of a deal but wanted to ask the people who are deeply into this stuff and see what they thought.
Thank you for the answers. []
