Using two Luxman integrated amplifiers together

I've never done this and don't know if it even makes sense or not but I thought the members could share some insight.

I have two Luxman amplifiers: a 550 axII,class A , 20 watts and the LX-380 integrated tube amp 18 watts. 

These can be used as separates so if I used the LX-380 as a preamp and the 550 as an amp would there be any sonic improvement? Or any other benefit/downside? Or would I just be wasting electricity?

I'm rotating the following speakers: Harbeth 30.2XD, Dynaudio Heritage Special and Devore Super Nines.

Thanks

May I ask how does the Harbeth M30.2 XD compare to the Dynaudio Heritage Special? Which one do you like better? I would expect the Heritage Specials to have better bass and dynamics than the 30.2 XD but which one has a higher involvement factor with better refinement and detail?

Harbeth is one of the best with human voice reproduction. Are the Dynaudio HS capable of matching the Harbeth in this area?

im trying to find the time to do a comparison between the two amps and the two speakers but I’m working too much.

actually the Harbeth sounds the best to me paired with a  musical fidelity 6si amp I have but the Luxmans tone controls let me tweek the sound to my taste. The Harbeth may be a little brighter and with some songs I prefer the Harbeth over the Dynaudio. There’s just something special about the DynaudioHS that lets me just enjoy the music though. 
Initial impression is that I don’t notice a difference with the two amps together vs separately. But it’s kind of fun to explore.

Finishing up a long week, relaxing, listening to Ice Cream Man by Ronnie Earl and the Broadcasters via Qobuz on the Dynaudio HS's  and it's like "damn that sounds nice".

Hello - One more guy keenly interested in this thread. I also have a Lux 550 MkII plus a CODA CSiB integrated. After a few years with Klipsch Cornwall IV speakers, I recently decided to experiment with open baffle speakers and bought a used pair of Spatial Audio M3 Sapphire's. So far, I'm loving them. The CODA is my #1, but I felt that I needed to pull out the 550 just to see what it would sound like. Kinda to my amazement, the 550 sounded quite close to the CODA when playing through the M3's - not so with the CW IV's. So, now I'm thinking of using the 550 pre-amp with the CODA amp and probably vice versa since the CODA has the same capability. I'll ultimately figure this out myself, but if anyone has thoughts or experiences to offer I'd enjoy hearing it. Especially results from the OP's experiment. Thanks!
