LM805 is very similar to LM508 except it bypass pre input tubes to be used as power amplifier.
Although LM805 has very deep and powerful bass with 48W, it still need to be mated with high efficiency speakers at least 90db/W to play Jazz with realistic volume.
Thus I would exclude Magico and Dynaudio.
Dynaudio is very power hungry. It will be worst match.
I had listened to several models of Focal speakers, not Sopra2.
But they have lot of things in common, clean and sparking treble out of beryllium tweeter. tight and powerful bass.
But Focal speakers are also power hungry despite the spec of 90db/w.
Sonus Faber which is more refined and suitable for classical music is also power hungry.
If you do not play loud, Focal or Sonus Farber may work with LM805.
You can also consider used Piega 60.2.

It also have sparkle with higher efficiency.
I had listened to other model of Piega in Audio Show.
They gave very refined treble with tight and tuneful bass (not very powerful like Focal).

If you like Jazz, you may also consider Pure Audio Project speakers with high efficiency.
I was also tempted to get one of Pure Audio Project speakers as second system.
One more choice is DeVore O/96 which works well with tube amplifier.
