Speakers for First Watt SIT-1 amp


My favorite sound seems to come from an SET amp and single-driver speakers but I want to leave the amp on all the time and I have kids in the house so I decided to exclude output tubes.  I went on a hunt for a solid state amp with an SET sound and landed on the First Watt SIT-1 monoblocks which I love.  I'm using them with Omega Super Alnico High Output monitors and it's a great combo but I wonder how much better speakers like this can get with this amp.  I have my eye on Voxativ, Teresonic, Audience, and maybe Audio Note or Daedalus.  Any suggestions?

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.
I was thinking Cube Audio was the way to go but based on that review (and others) it's hard not to second-guess.  It sounds like the Trio10 Voxativ is at least as good as the Magus if not better.  What I especially like about Cube though is that Srajan heard them with the SIT-1s and gave the combo the thumbs up.  The Trios require some (I think, basic) assembly and naturally they have crossovers although I hope the Voxativs have a direct line to the amp.  It's a tough call.  I do like the idea of four 10" drivers.
