Luxman leaves me wanting


My current system is a Luxman L590-AXII driving DeVore Gibbon Super Nines. My source is Lumin U1-Mini (w/Sboosterj and Denafrips Venus II. Also a Rega P3. Speaker and interconnect cables are circa late 90s Cardis Cross There is a lot that is right about the sound of my set up, but I feel it’s lacking fullness in the midrange. When I turn on the loudness on the Luxman, I get the meaty weight in the mids I’m missing, but at anything but low volume, it alters the sound in a negative way. 
I had considered a tube Integrated before I got the Luxman, but liked the L590 when I heard it. Now I’m wondering if I should have gone with tubes. (At one point I had a BAT Pre w/ a Classe amp and loved the bloom in the mids and vocals).               I’m attracted to the LTA 40+ from the good reviews and long tube life. I’d be interested in hearing one with my speakers, but there are no dealers, so I could buy and return if I’m not thrilled, but wanted to know anyone has heard the 40+ with Super 9s. Also interested in other options to get a richer sound. Budget is around 8k.

Also, consider the PrimaLuna EVO 300 integrated from Upscale Audio. They have a 60-day return policy for a full refund, so you really have nothing to lose!

As brother ghdprentice said, and speaking from extensive experience with a Luxman 550AXII, the word "sparkly" is an apt descriptor. The Lux offers a lot for the money, and I enjoyed that amp quite a bit. But ultimately decided to delegate solid state integrated chores to an Accuphase E-280, which I simply find more relaxing, less "hi-fi," warmer.less analytical, and easier to listen to. The one thing I wish the Accuphase had is a loudness control button on the remote.

Now if that isn’t a first world nitpicking, please tell me what is. :)

The "lack of fullness" in the midrange is not the Luxman’s fault...it’s that useless speaker known as the Devore ’Gibbon’ that you are running with.

(Surprised some poor lil cable didn't get blamed for the scooped out midrange, 😂)

You have some good gear. the only thing I can think of, is the Amp and speakers are not a good pairing. My sudden Class A amps pair well with Dynaudio and Capriccio Continuo speakers. I have 2 systems, the main floor has always supported Dynaudio speakers. I have never ben able to get Dynaudio to sound great in the basement. before you go replacing gear, try fixing the room.
