Speakers for First Watt SIT-1 amp

8ohm 99 db Klipsch Heresy IIIs...best 1500 bucks I've ever spent, they sound sublime (and un-congested) with my little SE tube amp and a couple of RELs. Besides, they're from Klipsch so there's zero snobbery as you can say they belonged to your dead uncle Bob.

Re: the The Cube Audio Nenuphar

I would love to order the drivers and take a crack at building the cabinets myself.

Doesn't look to hard - right?

Hi David
Thanks for the correction regarding the Cube Audio Magus and the Cube Audio  Bliss C models and 6 Moons review/Blue Moon award. I should’ve looked it up to be sure rather than relying on memory.

Charles, you are welcome.

@ggking7 I recommend reading their review of the PAP Trio 10 later in the same year (12/2017).

Understand that you are comparing 2 10 inch woofers per OB speaker (from 300 Hz and below) to the LF from an 8 inch single driver TL speaker.

Regarding the SIT amps and high impedance loads.  I tried out a SIT2 with my Coincident Super Eclipse III speakers (14 ohm nominal, 10 ohm minimum) and Nelson Pass had me buy a couple different resistors to add across the speaker terminals in order to increase the load.  He said that the SIT2 would sound a little dry and clinical when coasting on those easier loads and would warm up if I added some additional resistance.  Apparently using different resistor values was equivalent to using the manual adjustment knob on the SIT1s.  I just bring this up because I think Nelson made the amps with a nominal 8 ohm load in mind (or at least something below the SEIII's 14).  

If I were you, I'd consider e-mailing or calling Pass for a few speaker suggestions. Probably no-one knows as well what speaker will excel on your amps, and both Nelson and Kent English at Pass are always super nice and happy to provide input.  Personally, I think it would be a disservice to your search not to find out what they suggest.
