Topping D90 vs Loxjie D50 vs SMSL M400 vs SMSL SU-9

[Cisco150]

I now have the Topping D90, the Loxjie D50 and a Denafrips Ares II

Let me know if you want me to give some comparisons.

I would like to know more. I have 3 Dac I can choose from the SU-9N for $340 and the SU-9 for $460 and the D1SE is ordered for $152 more then the SU-9. Or the M400 for around $730 everything is usd

I own the M400 and it's transparent and I have no complaints. I bought it because it was able to handle MQA, which I'm finding that at 65, I can't hear the difference. With that said, is there any reason to own the M400 for $300 more than the SU9? It seems to have what I need for a USB in and XLR out. Where's the additional value, that I'm not seeing or taking advantage of? Thanks.
