I've owned the Line 3 for about 2 months. I auditioned the BAT VK50SE, the 5i's big brother at the same time. The Line 3 has better base and they tie in the imaging department. The Line the also has a more extended high end and is dead quiet. The BAT is slightly more musical, the Line 3 more neutral. Go to the Sonic Frontiers web site for reviews. For me the decision was cost. I purchased the Line 3 here on Audiogone with new warranty cards etc for $2650. What amp and speakers do you have? My Line 3 tamed my Krell KSA200s and Thiel 3.6s into a most musical liquid sound. Also upgraded to Alpha Core interconnects/speaker wire that made vast improvements.
