The Fluance RT85’s plinth-mounted servo-controlled D.C. motor isolated via a six-point rubber decoupling ring and powered by an outboard “wall-wart” type power supply drives the 12”, 3 pound acrylic platter at either 33 1/3 or 45rpm, via a flat belt placed around its periphery.
The spindle bearing protrudes from a plinth opening hiding from view the bearing’s support structure, which must be relatively high mass given the ‘table’s almost 17 pound total weight. The plinth itself, available in either gloss wood or gloss black finish, though of relatively high mass MDF (compared to wood) can’t alone account for most of that weight even considering the platter and motor weight. The plinth sits one three height-adjustable elastomer feet
The static balanced “S”-shaped approximately 8” arm terminated with an H-4 Bayonet mount head shell has an effective length of 224mm, an overhang of 19.2mm and a relatively high effective mass of 28.2grams by my calculations, the arm is slightly too heavy for the cartridge’s relatively high compliance, putting the system’s resonant frequency at around 7Hz or one Hz below the ideal 8-12Hz range. However, in practical terms it is not problem).
Fluance’s RT85 Turntable Is a High Value Proposition
Canada-based Fluance’s $250 RT81 reviewed here a little over three years ago was a pleasant surprise. It offered reasonably good mechanical and sonic performance as well as useful convenience features and attractive looks. Fluance’s new RT85 Reference turntable doubles the cost to $499.95. Is it...
