IMHO....
Get your sound with what you like....
MESA quality and customer service is superior....
No I'm not endorsed by them....I've only played through MESA that sounds amazing... Eventually I'd like to swithch my whole rig over... Currently using TF550A that is awesome or BBEMaxT w/600+watts per channel Carver-Claire Bros. Power amp or Line 6 LD400HD and waiting on Shuttle 6.0... ALL sound killer through my MESA Powerhouse 600 2x10 cabinet at only 8ohms.... when linked with my 1989 SWR Goliath 4x10 and paired down to 4ohms.... The MESA sounds as big and full as the SWR...
The MESA 4x10 + 1x15 is fantastic and really sounds amazing with the Carbine M6 or any head of theirs you prefer....
