My experience and mine alone - I use a Lumin, U1 Mini (has no DAC) fed into a Line Magnetic, LM502ca Tube/SS DAC with extaordinary exotic NOS tubes. I also have a Canor, DAC 2.10 that I’m rolling better tubes into soon but right now, I prefer the LM502ca as I’m super used to its presentation. The LM was $1800-ish 8yrs ago but go for about $8-900 preowned today, also, (new tubes $500). The Canor was $4K and the Lumin was about $2K & the S Boster (a must) was, I think, $350. Money invested seems to be in step with the equal dollares spent on each, prob by coincidence, however it’s an amazing streaming set up. I use an Audience, AU24e Digital BNC cable as well and AU24e RCAs to my Calypso Signature prefering those connections to balanced. My feeling is that the Aurender may be overkill in your system unless you plan to up your DAC game at some point. Albiet a wonderful piece, you wont know just how great that Aurender can be unless you, and deoesn’t have to be right away, upgrade your DAC. Oh, and yes, would be helpful to know the rest of your gear. $6K+ is a "real number" and I don’t think you need to spend that to realize great streaming. It’s more about choosing the right pieces. Just my opinion & I wish you luck!
