TMR Safe Pack & Ship Guarantee

Our Safe Pack and Ship Guarantee means we guarantee its safe arrival. Items are carefully double-boxed or custom foam-molded. For larger pieces, we palletize to ensure secure, upright delivery. In rare cases of loss or damage, we fully protect your purchase.

Shipping Cost

Shipping within the Continental USA is $699.00—this includes securing to a pallet with adequate protection and shipping via FedEx Freight to a residential address anywhere in the Continental USA. This rate can be reduced by $60 if a commercial delivery address is available or if the item can be picked up at the nearest FedEx Freight depot. FedEx Freight charges a residential delivery fee otherwise, which is included in our flat rate charge.

We DO NOT offer international shipping.

Product Highlights

The Riviera Labs AFM-50 monoblock amplifier delivers 50W at 8 ohms and 100W at 4 ohms. This Italian-made hybrid features an "Aural Optimized" design, merging tube voltage warmth with MOSFET power. Operating in pure Class A with Zero Overall Feedback, its circuitry uses a Triode, BJT, and Mosfet combination. It includes one RCA unbalanced and one true balanced XLR input, providing a remarkable foundation for effortlessly driving premium loudspeakers.

Critically acclaimed by Mono & Stereo, the AFM-50 delivers a "warm, natural dark-like nature" with the realistic density of live instruments. Reviewers praise its output as both "puissant and silky." Earning recognition at the RMAF Beatnik Bongo Awards, it is widely considered a hidden gem in the high-end audio community. Its uncompromising acoustic design makes it a definitive cornerstone for any elite high-fidelity reference system.
