Upgrade from Silverline Sonatina IIIs


I would like to upgrade from my Silverline Sonatina IIIs, used or demo in the $6K range. Listen to jazz, blues, oldies and acoustic. Do not really know this range. Love the Silverlines other than bass slam. Considering Montana Liberty, Sonus Faber Cremona M, Legacy Focus SE, or other suggestions. System is Cary SLP98 F1 direct coupled into Manley Snappers. Digital is Wyred DAC2-DSD fed via Mac or transport. Analogue is Oracle Delphi MkIV/V with Morch UP-4 arm. Cabling is Audience Au24 SE. Room is 15 feet deep by 21 feet wide with 9 foot ceilings. Have also thought of swapping out Manleys for Modwright KW 100 SE. Thanks for your thoughts.

Though they don't seem to appear on Audiogon often, the Silverline Bolero might be one for you to consider. Another speaker line I hold in high regard is the Canton Reference Series. A 7.2 or 5.2 might be ones to consider but I'm not sure what prices they command on the used market.
