I'm using a Mystere IA-11 integrated amp w/ 40 wpc. It is meticulously built by sister company Primaluna and is on sale at Up Scale Audio. It uses high quality parts and even a ladder resistor volume control instead of a potentiometer. Sound is clean and articulate w/ tight bass, tubey midrange, and extended highs. http://www.mystere-eu.com/usermanuals/mystere_manual_ia11.pdf |
Would you want to power all 4 speakers and the sub with the integrated? If so, you're going to be hard pressed to find a low cost tube integrated with more than two sets of binding posts, much less a sub out. Have you checked into an upgraded NAD?

sub has its own amp, thought this could be my tube opportunity. Would like to have all four working. |

Sounds like from your post you are looking for something affordable to pair with those speakers. I can say Jolida and Cayin both have some great sounding integrated amps for good prices especially used. |
