Hi Eddie
You seem to be enjoying the search for new sounds, as well you should be. It's one of the simple pleasures of life afforded to us audiofools

I've not heard the AN Js, the Blus or the Trigon amps, so do keep that in mind while considering my $0.02.
Some personal observations:
- I've heard the hemp-coned 97db AN E with a 180 watt Halcro power amp and an Audio Note 8 watt SET. The former produced a clean, pure sound with loads of dynamics and taut bass. The latter was sweeter/lusher with a softened bass at higher volume levels. However, the intrinsic sonic character of the speakers did not change.
- The reason I keep bringing up sensitivity is because I believe it makes a huge difference. Music seems to flow out of sensitive speakers with a sense of gay abandon, while insensitive ones seem to huff and puff and run out of steam. Sensitive speakers also give you a wider choice of amps. And allow you to explore the magical world of lower powered tubes.
- Great to see a dealer offering a home demo! No better way to judge if a component is right for you.
- In your place, I'd go for a pair of AN E speakers first. Then, when funds permitted, switch out the Trigon for a ~30 watt tube amp like a PrimaLuna or Line Magnetic, perhaps. Or, just switch to Blus, keep the amp for some time to come and blow up the savings on more music!
But, that's just an opinion. In the immortal words of Inspector Callahan - "Opinions are like a-holes; everybody has one!"

Happy hunting!
