Steve Huff in his reviews, said the 2 streamers (Lumin U2 & RS-130) are very close, but a slight edge to the Hi Fi Rose RS-130 streamer.
Did he also mention that the $1,400 T8 gets fairly close to streamers in the $6k range, with an app experience he actually prefers? The only aspect of the T8 that may not please everyone is its brighter house sound, though it should pair very well with a warmer system.
