To get best sound quality, roon or lumion app?

I never use any upsampling, quality is always worse.
Using T2 and for me Lumin app sounds so much better, that I cannot even use Roon due to the poor quality when compared.

Don't you guys find it annoying to pay a subscription fee for roon (considering its offline software) or did you buy lifetime?
This is what motivates me to get a lumin device so I can use the lumin app instead.

actual sound is same if you dont use dsp but lumin app is one dimensional doesnt support zones... roon ui is much better and function more versatile, worth a lifetime subscription and has flexibility to add hqp for dsd upsample if that floats your boat

FWIW: I posed a similar question when comparing Roon vs. Lightning DS (Auralic’s control app) as I was perceiving LDS to be superior to Roon.  It turns out most LDS users have concluded the same.  

I share this experience here because I wonder if the native apps  have an easier time managing data packets and memory buffers/cache than Roon does because the latter needs to work on multiple platforms.

There’s no question Roon is the best UI, but I don’t think it’s the best sounding.  It certainly isn’t for my system and it wouldn’t surprise me if that was true in a Lumin environment as well.

Agree entirely. My Bluesound App sounds better than Roon, which is somewhat thin and loveless sounding. As userinterface Roon is firstclass.
