U1 or U1 mini best for my setup


I’m fairly new in hifi so I thought I ask the pros here for some advice.
I would like to get a transport to replace my mac mini/Audirvana/MicroRendu setup.
It will feed my Chord Cutest DAC - Rogue RP-1 Preamp and then to my Rogue Magnum II tube amp.
My speakers are Vienna Acoustics Mozart Grande SE and a Rel S510 sub.

My question is my system high end enough to benefit from the extra cost of the U1 over the U1 mini?
I listen to mostly Jazz, smooth jazz type stuff. I have a library of redbook all the way up to DSD.

Thank you

So yes I have my own DAC. Chord Cutest.
i have a chance for a new U1 for $4450 or used Mini for $1800
My mistake neither have a DAC. Looks like the U1 can upsample to higher rates than the Mini which your DAC would need to support. 
This is incorrect. Neither of them have a DAC.

I have been very happy with my Lumin U1 mini. My only complaint is that Qobuz and Lumin can’t come to some understanding about sorting music. There is no provision for sorting albums in Qobuz and both blame each other.

I believe the main difference is the Mini doesn't have a DAC so if you use your own DAC I would get the Mini if those are the only two you're considering. 
Just buy the cheaper option.


Yeah, cause it all sounds the same to this guy. He’s still listening to rack system from Sears.
