Luxman L505uXii or Hegel H390

both very good

what speakers are you using. And do you have a local dealer that will allow you to home demo the integrated's? 

Both are fine amplifiers, but you are comparing apples to oranges.

What kind of functionality do you need. The Luxman is more on the analog side, or somebody who has multiple sources. The Hegel is more on the digital side with its built in DAC and digital connectivity.

Do you need the tone controls, on the Luxman. Do you need the power of the Hegel.

You need to give some thought as to what you expect or want out of each.

As for sound quality - no comment.

Luxman.

+1, Luxman.  Of course, if possible, I suggest you audition both amps.  

No contest......I would go with the Hegel H390.  First: with the Hegel, you get a supremely powerful and high current/damping factor unit (that's built like a tank) that will even drive my power hungry, highly inefficient Revel Salon 2 speakers to astonishing results.  Forget about all it's other features for now, and know that as a stand alone amp/preamp, this thing is one of the very best sounding integrated amps on the market, hands down.  If I had a larger room, I'd go separates.  In my room, though, I didn't even feel the need to go with the more powerful H590 to drive my speakers.  The H390 is definitely a world beater and one of the true high value to performance unit on the market today.         

Depends on your speakers and your taste.  Both are excellent products but can't suggest one without knowing more.  

Tough choice--agree that it probably depends on taste and synergy.  It's kind of hard for me to imagine the lowest tier Luxman beating the penultimate Hegel.  I had the H390 and currently have the Luxman L-509X.  While I think the Luxman is the better and more natural sounding integrated, the Hegel comes pretty close on technical merits, and it just may be a matter of preference.  I heard the L-550AXii, and while certainly musical and enjoyable, I felt it lacked the depth, detail, and precision of Luxman upper end amps to a noticeable degree.

I would take a Luxman over a Hegel any day. I heard a Hegel integrated for the first time (not sure what model), a very painful listening experience. Over the years, Luxman's have continued to impress me! As a previous poster stated, "Hegel is more on the digital side" It is so digital that I actually heard 1's and 0's coming out of it.  

Doubtful it was the H390, which is anything but painful and "digital" sounding.  It's smoother and a bit darker than the 509X.  However, I have read that prior Hegel models, and I think those below H390 or H190, do have a more sterile and "neutral" presentation.

Luxman!! You may think resale value means nothing now, however, it will if you decide to move on. My research, due to purchasing an integrated amp, shows pre's or integrated with built-in dacs has much lower resale value (after the model has been replaced) than "non" dac units. Built-In .Phono pres do not hurt the resale value.

Another thing. Luxmans BUILT in Japan. Hegels built in China.

Sound quality is important. However, if certain criteria are not met, there won’t be an intention of a listen or purchase from me.

The Hegel amps look fine. They are used by many and have been endorsed by the Harbeth designer Alan Shaw for Harbeth speakers. As a Harbeth owner myself, I disregarded the Hegel mainly for the looks and build quality. The front panel looks like it’s made of plastic with matte finish which reminds me of budget NAD amps. Sorry. When you open the lid and have a peek inside, you would notice that the wiring is little messy. As for the Luxman, the build quality is far better. The material used for the construction of the case, the thick front faceplate (almost an inch thick), there is a certain solidity feel to it. And the meters. Have a peek at the innards and one would notice the neat arrangement of the wiring, parts and components.

It’s just one man’s opinion so please don’t take it seriously. No hard feelings. Similarly I wouldn’t bother too much about negative comments made on the Luxman.

When I spend big money on a hifi component or an amp of say above $5k or up to $10k (only applicable to my standards as the amount may be regarded as peanuts by others), it’s not all about sound quality. The equipment has to satisfy other requirements as well which will be dependent on the individual’s personal preferences.

To each his own. I’ll get my coat.
