Building my 1st real system. Need advice. Hoping to pair Luxman507uxii/Dyaudio Evoke20.

@mrcorky - seems you want a musical and forgiving set-up.  Maybe Harbeth+Hegel combo- great sonic match.  The Hegel H360 or H390 optional DAC is fairly good.  

I have the Luxman LX-380 and a 550axII and love the Dynaudio Heritage Specials with both of them. Lux and Dynaudio are a great match.

Thanks. Looking forward to my system. Still working on figuring out the dac/streaming situation though!

Glad to hear you got the Luxman you wanted. 

Evokes will arrive at the shop in about a week. They didn’t have the finish I wanted. I think I have a nice little system now!

.Sonus Faber Sonetto ii(would be great with vocals, but I don't know how it would do with low quality heavy distorted guitars)

Sonus faber. would be fine, any speaker will work well with your 507.

No, I purchased the 507XII. I've been calling around to see if any dealers had any still available, and a dealer not far from me had a brand new sealed one. Not that many Luxman dealers near me, so I sort of lucked out.

So you purchased the Luxman 505?

Thanks for all the suggestions. Ended up really liking the Evoke 20/Luxman combo. I think I’ll be able to live with this pairing for awhile. Was tempted to start considering floor standers but feels like overkill for the room size. Next step is to decide on the Dac/Streamer.

Take a look at Raven Audio.  They have a very nice line of affordable and great-sounding integrated tube amps, cables and speakers within your budget.  They also have a 45-day money-back guarantee.  Call Dave Thomson at Raven.  You will be surprised at the quality of sound from Raven.  I think you can get the amps, speakers and cabling for under 10K and they would be coherent with each other.  If DAve is not available try James Connell, one of the other owners.  Look at their website.

Better than any other audition....

I don't know much about ATC , but it's piqued my interest! I will do some research on this line and see if I can check them out locally first.
Unfortunately, I just found that the Luxman 507XII is discontinued and will be upgraded mid 2022. Music directly had it listed as no longer available, so I contacted Luxman America directly and inquired. I'm stunned since the Mark 2 507 isn't that old! When I first saw the no longer available banner, I assumed they meant no stock or something. Pretty bummed now.
 I need to determine what I'd be gaining/giving up if I went with the 505 VS 509 for the style of music I listen to. 509 is definitely above the allocated 8-10k budget I promised myself I'd stick too so unless I received a steep dealer discount or open box (which I'm very cautious of) it's highly unlikely a 509 is in my immediate future! Also, I have a real soft spot for the blue VU meters! 

I pinged a somewhat local dealer today to ask if they had any old stock of the 507xii, but I'm not optimistic. I just need to determine how much of a compromise the 505 would be for my personal preferences. 

I ran a combo of Musical Fidelity A5 integrated and ATC SCM11v2 for about 2 years.  It was a very good match; the grunt and grip of the A5 powered the ATCs with very satisfying sonics.  The ATCs are incredibly fast and resolving - but not bright.

The only drawback of the ATCs is they do need a sub to round out the low end and they do need some volume to 'wake' them up.  I found at mid to higher volumes the ATCs are amazingly good.

I then upgraded the MF A5 integrated to the Luxman L-509x.  And they took the ATCs to a different level of performance. 👍

But, in the end, I wanted a better pairing and went with Audio Note AN-K/Spx SE.  Very happy with this!

For your music I’d highly recommend the ATC SCM7 or SCM19 if you can stretch a bit.  They’ll blow you away with rock, electronic, etc., and although they’re more in the neutral camp pairing them with the Luxman and a good R2R DAC would likely produce a very natural yet still extremely dynamic sound.  You can get both the Luxman and ATC from Music Direct, and they have a 60-day satisfaction guarantee so that might give you an opportunity to demo them with low risk.  But, I think this combo will exceed your expectations by a good margin and highly doubt you’d return anything.  Hope this helps, and best of luck.
