I have a Sonic Frontiers line 2, my friend had a VTL 2.5 we tried with many various systems. He sold the VTL at a great loss, I still have my pre-amp and plan to keep it for quite some time.
Classe vs. Sonic Frontiers
I currently own a Classe 5 Pre and power combo. I am wondering if changing the pre to a Sonic Frontiers Line 1 or greater would be a huge improvement. Also would be interested in the phono 1 to replace the internal phono in the Classe. If anyone has experience using Sonic and Classe let me know what your findings are. I am powering Proac speakers with this setup.
