Using two Luxman integrated amplifiers together

I think you should do this all as a personal experiment because I'm pretty sure you'd learn more than anyone here.

There aren't really downsides, but I do find the SS preamp stage in Luxman integrated amps to be excellent performers, so I'd be curious to know how you compare the two preamps driving the same amplifier.  What might also be fun is if you had speakers to biamp as well.

I don't see a problem, plus you could try it both ways (SS pre/tube power - tube pre/SS power).

When using the tube preamp section be certain to turn the tube amp on first before turning the SS amp on (reverse this when powering down the units).

The combo's should not waste much, if any, energy VS using them as stand alone units as you will only be using the power amp section of one unit @ a time.

As the others say try it you own both components so nothing to lose. Curios myself which combo will sound best.

It will.sound good! L380 is awesome musical.tube pre and imtegrated.

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?
