Found this thread because I'm very seriously considering the qualio iq. It seems to have everything I'm interested in from a technology (and expected behavior based on that tech). I've been interested in cube as well but haven't auditioned yet. I'm going to go listen to some nenuphar mini that aren't too far away as I expect that will give me an idea of what the IQ will do in the mid range. I am 100% confident the soundstage and imaging will make me happy based on the video they posted on YouTube (played through dartzeel and reference 3a speakers, the only thing I can really determine is soundstage imaging and dynamics but what I hear confirms what one should hear with this design). What I'm concerned about is mid range and vocals, coming from harbeth I'm picky about that and trained to really appreciate warmth and life like timbre. If the cubes make me happy in that regard I'm going to order. The price is fantastic even including shipping taxes and duties.

Post your thoughts on the Nenuphar mini’s once you get a listen. I’m intrigued by the semi OB design of the qualio iq’s. I love my Nenuphar mini’s but I’d love to listen to the qualios one day. 

Stereophile has a review by Ken Micallef of the 25W Pathos InPol Remix MkII integrated amplifier. The specs caught my eye as the output impedance is listed as 0.9 ohms. As the Nenuphars have an impedance of 8 ohms, this would make the damping factor

8/0.9 = 9

which is pretty low and down in the tube amp range. The SIT-3 has a damping factor of 30.

 

If anybody gets a chance to audition the Pathos please keep us posted.

Good observation. This is actually what the Nenuphar was designed to work with due to the highly damped driver implemented.
