To answer a direct question to me my Thiel are CS1.2, one speaker sounds great, the other one sounds blown, when I removed the grill found the tweeter was crushed, so have to replace both, not currently in a hurry for that.
To follow along with OP thread, and ideas, I went first with ProJect streambox S2, quickly returned it, ordered a ProJect Streambox Ultra, currently using it with a USB hard drive directly connected to the Ultra (which is really a raspberry pi running volumio), the audio is, so to speak crystal clear, since it is early in the morning I have not played audio too loud, don't wish to disturb neighbors, but I now have the audio quality I was seeking for a relatively low cost, well, compared to some.
