Luxman Integrated - What do they sound like

hmm...not sure I understand what you are asking.  But I will try.

The Luxman is always in idle unless you unplug the cord.  So pushing the power button on the unit just takes it out from idle and it's ready to go.  It gets warm in about 30 minutes. Meaning that the heat coming from the vents is nearly peak in that time.  However, other factors can alter this such as room temperature and how hard it is being pushed.

The heat is not such a big deal for me.  I placed it on the top shelf and I have a 65in TV right above on the wall.  Never has been an issue.  But I don't leave it on all day either.  

The 590AXII that I have tried at home for the past week with my Spendor D9's warms up fairly quick. Even at peak though, the heat is really not bad at all. I can keep my hand on it so that may tell you something. It is a great sounding amp - one that I like over the 509X but that's me coming from a tube setup. 

Thanks so much for the replies, @jasonsim

It's not actually heat output I'm worried about so much as sound quality, I was trying to assess how long I would have to turn the unit on before it sounds its best.

Thank you,

Erik

Erik, it sounds very good immediately, and the best after 20-30 minutes, I'd say.

HI Erik.  I'm not sure I'm trained enough to notice any perceivable different between just turning it on and after about an hour or so warm-up.  The sound is great immediately.  

When you take the unit out of idle, there is a 8 or so second period where nothing is audible, even if you have your source playing.  The light on the unit blinks during this time.  Maybe this is all the warm up needed.  Perhaps a more seasoned Luxman fan can explain why this happens.  

I have a Cambridge CXA80 integrated in another room and it can play immediately, after taking it out from idle.  It has also been a wonderful and surprisingly good sounding (warm) amp.  Amazing sound for the price.
