Lumin X1 dont see many virtual audiogon systems with this?

Ps direct stream is just a dac.  Lumin x1 is abit more.

My Lumin X1 is an excellent sounding streamer DAC.  I also appreciate the fine support Lumin offers in software updates and features, such as the LEEDH processing optional engagement, which is excellent and very convenient is one wishes to go direct to amp rather than use a preamp.  Peter Lie of Lumin very actively participates on a number of forums and is an excellent resource for quick response on Lumin questions/issues as well as offering pertinent general audio advice. 

Regarding Tambaqui, I have not had the opportunity to listen to one, but from numerous reviews and postings, is considered an excellent piece as well.  I, too, had been interested in how these compare, and I have only found a reference of both in a 6 Moons review, https://6moons.com/audioreview_articles/lumin8/5/

I think a lot of audiophiles probably have to dismiss it because it doesn’t have digital inputs. 
As great as it sounds, I could never entertain owning it because it’s limited functionality. 
For 14K, or whatever the current going price is, it should have an optical and SPDIF input for those who have additional sources like TVs, Transports, etc.

So lumin x1 is not liked by audiophiles? So seems this is not a very popular component, ie. Lumin x1. Who dont more buy this?

so tv optical cant be input to thie lumin x1?  What stream allows optical from a rv?

I am a happy X1 owner too, since last week I have the Lumin Amp as well.
Previously I had the very fine Aesthetix Atlas Amp (Eclipse version) but I find the Lumin X1 - AMP combo even better.
And I don’t think that the X1 should have more inputs just because it has an integrated DAC.
Why an earth would anyone connect a TV via SPDIF to a 14k audiophile player? 
It was designed to play virtually any high resolution audio format from an USB source or stream it from a local network and internet, and it does that perfectly.
