Little Dot MK VII+ paired with a HD 800?

Current setup:
Little Dot Dac I > Little Dot MK III > HD 650.

I expect to get a HD 800 in the coming years. But before I get there I would like to replace my LD MK III with the LD MK VII+ (Little Dot Amplifiers • View topic - Little Dot MK VII+ Balanced Headphone Amplifier).

Now will the LD DAC I + LD MK III be able to drive the HD 800 enough to hear a significant difference between the HD 650 and the HD 800?

I plowed to the entire forum and couldnt find any impressions with cheaper setups. I mean, I hear a lot of people saying that they cant afford the HD 800, but will be able to get one in a year a two. But why bother when you have to buy a setup that is way more expensive than the HD 800 itself. 900 euros for a headphone is still doable for me, but its a no no if I need to replace it with a 1000 euro amp (and if I am correct, a 1000 euro amp is still considered to be very, very low end for the HD 800).

Do I just need to accept the fact that a HD 800 setup is way out of my acceptable price range?

But do they sound better? Or will HD800's superiority only show with more expensive equipment?

According to the HD 800 reviews its superior in a number of areas to the 650. So my definition of better/superiority is based on those reviews.

I choose the LD VII+ because I read that its hard to beat in that particular price range.
All my choices are based on reviews/impressions on this forum, auditions arent really possible since I seriously dont know where to look (I live in the Netherlands, most stores you only get to test speakers).

Any recommendation for another headamps are very welcome.
Or just kill my dream and tell me to stop looking at the HD 800.
I am prepared for any answer.

ps. I like a laidback, non-aggressive sound.

How's is the soundstage with ur current setup? Is it enormous? Or at least significantly wider compared to the 650?
