ACCUPHASE d-570S VS. LUXMAN D-07X SACD PLAYERS

I have directly compared the Luxman DA07X, the standalone dac that is identical to the dac section of the D-07X player afaik (barring some power supply differences) to the dac section of my Accuphase DP-550 player which is two generations older than the DP-570. The Luxman felt somewhat more refined, with a relaxed and surefooted way of presenting detail, and the separation was a bit better iirc. However, the Accuphase had better tonal density, was weightier and punchier, warmer, more organic (but treble extension was still very good) and to my ears "more musical", I enjoyed it more. I’m not so much in love with the DP550 as a CD/SACD player, it is a bit polite to my ears, but as a dac it’s wonderful. A few years earlier I had also heard the Luxman D-07X’s big brother, the D10X, and it was wonderful both as a player and as a dac. If you go the Luxman route, perhaps you could stretch it to the D10X, it might be worth it.

Of course, hearing these machines yourself is very much indicated, if not even mandatory. Fwiw...

Are you looking at the device to be multiple purpose?  Cd and sacd and also function as a DAC?

I currently have a Accuphase e-5000 amp and have previously owned luxman turntable and amps.  I love the build and sound signature of both brands.   For cd playback as someone mentioned definitely also check esoteric, and i eventually ended up getting a cheaper but it is no slouch, the excellent Shanling scd3.3.  I use this for sacd playback and as a r2r ladder dac for my room/Hqplayer setup.

AI also liked the Luxman sound better

That's funny!

I am investigating Digital Source options and have been learning that Sources deliver their presentation of an end sound with a different 'tempo'.

My own resident Source is referred to by me as very comparable in delivering detail on parity with other Sources used, but does have a slowness to the 'tempo' of the delivery that is noticeable in the end sound. I really like the resident Source, but have developed a very strong attraction to the speedier delivery noticed in other used Sources.

The OP is best to learn how they prefer the 'tempo' of the end sound produced from models on a shortlist; these options and others to be proposed come with a fair cost. 

Having experienced many devices from both brands over the years, I concur with  the summary @donquichotte posted above. That is generally how I hear the house sounds of each brand as well.

Luxman has a greater focus on resolution and speed, while not being overly fast or thin as some other devices can be. Separation and layering are strong points, as are imaging and soundstage expansiveness. It is a nicely balanced tone and fairly universally compatible as far as pairing with other components from different brands.

Accuphase does tend to have a more tonally rich presentation, with smoother and more relaxed feeling on the top end. Not overly dark, but somewhat mellow while still giving quality detail and resolution. Warmth is a big factor here, Accuphase has plenty but again does not go too far. This sound will pair extremely well with certain gear and not very well at all with other gear. So more picky than Luxman in this regard.

Someone brought up Esoteric which should always be in the conversation when it comes to top caliber Japanese gear. The older models could get overly bright and thin, but once they developed their discrete DAC solution that all changed. 

Lastly, a somewhat lesser known but similarly capable Japanese brand is Soulnote. Tiglon Japan uses the top Soulnote equipment (plus a few Luxman pieces) in their quality control room where every single cable is tested prior to shipping out. 

Is there any way to audition any of the devices you are interested in? That really is the best way when making a substantial purchase like that. Soulnote would be challenging but you should be able to find some or all of the other three brands from dealers in your area who can arrange a demo one way or another.
