If you would like to already fogus on buying Sonic Frontiers Line-1 just go ahead and get one for yourself and that's good thing. if you ask, should it improve your system? I'm not so sure but I really think it should sound better overall as I did audition both pre. I prefered Sonic Frontiers Line-1 over Classe`5 pre.
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.
