Rock music on thiels aren’t bad as long as it’s well recorded... running luxman 510x as a pre and adcom gfa 5800 as a power amp with a pair of thiel cs 3.5. This might just be my opinion cause I only have the 3.5. Selling my second stereo to get a musical fidelity tri vesta 300 and then to get a thiel 3.7 for the tri vesta.
