I own Treo CTs and matched them with an Aesthetix Mimas integrated on the suggestion of John Rutan of Audio Connections. The Aesthetix is a zero-feedback design as are Ayre products and both are acknowledged as good matches for the Vandersteens. I like streaming as well and use an Innuos Zenith and Phoenix to stream to the DAC module in the Mimas. I use WyWires Platinum USB cables. The Innuos is my Roon Core and I stream with Qobuz. My points are to talk to Johnny and get his advice on amp matching. And the other point is that a a high-quality stream is readily discernible as superior.
Integrated Amp upgrade path
I’m currently using a Macintosh MC 8900 to drive Vandersteen Treo CT’s, with a six pack of Rel S510’s, streaming only. I understand Boulder will shortly have a software upgrade for the 866 that will include an Air Play equivalent to allow full use of most streaming services. Looking for thoughts from anyone with experience with the 866: how much of an an SQ improvement with this upgrade? Incremental? Immediately noticeable? Thanks for any help!
