Building the Audio Note Kit 1 SET amp...

I'm hard pressed to see how it could be called a good match if truly not that efficient in the bass but may only need match to a certain extent depending on listening volume requirements and room size mainly. Its not working properly currently would seem to be the consensus so there is still a chance.

We think we are zeroing in on the problem! More to come!

The de Capo's are 92 dB, with a 6 ohm minimum impedance - - pretty friendly to tubes. My 35 watt EL34 pp integrated amp can barely crank up on the dial (I wish the speakers had a little less sensitivity!).

It has been pointed out earlier in this thread that the actual sensitivity of the speaker is in reality 86 to 87 db. Jbrrp1 in your case your may have surplus system gain.

Jbrrp1,
Yeah my Manley EL-84 push pulls in triode mode (20 watts) drove the De Capo's plenty loud with no trouble.
