Bring the Cinematic Experience Home

Add the A51 to your home theater and watch—or listen—everything transform. This five‑channel amp effortlessly boosts your AVR, powering your front and surrounds with clean, room-filling performance that punches well above its price.

Designed by John Curl, the A51 runs high‑bias Class A/AB in a direct‑coupled topology for maximum clarity. It delivers 250 W x5 into 8 Ω (400 W x5 into 4 Ω) with THX Ultra2 certification, fed by a 2.2 kVA toroidal transformer and 164,000 µF of filter capacitance for clean current on demand. Balanced XLR and RCA inputs make it a drop‑in upgrade for any AVR/processor with pre‑outs.

Praised by audiophiles and reviewers alike:

  • “Midrange was totally seductive…with music, the A51 radiated sweetness and light. With action films, it rained thunder and lightning.”  Sound & Vision (Barry Willis)
  • “Benchmark levels of performance at a reasonable price.”  Home Theater Review
  • “More than capable of driving any speaker load…a true winner!”  Audioholics

Gorgeous summer glow anytime
Color: Glistening Bronze #03, Size: 1 Fl Oz (Pack of 1)
The body shimmer is like being kissed by warm summer breeze a glow of star dust. It lights not sticky or tacky. It gloriously luxurious but simple way to step a look.

Cute, Smells like Chemicals
Color: Rose Gold #01, Size: 1 Fl Oz (Pack of 1), Color: Rose Gold #01, Size: 1 Fl Oz (Pack of 1)
Looks great but transfers easily. I liked the shade and how the glitter was visible but not distracting. I wasn’t fond of how it smelled but I covered the scent with my sunscreen and I didn’t notice afterwards. Smells like a chemical like scent but it was worth the value I paid for. Good as a highlighter, to add a touch of glow to the face. You can’t see it under foundation but it’s cute on the cheek bones to give a make up less look on a sunny day. The brush is also good quality.

Quick glow up
Color: Glistening Bronze #03, Size: 1 Fl Oz (Pack of 1)
This is a great bronzing shimmer for a little added glow before walking out the door! It's very lightweight and goes on very smooth with brush. I ended up buying and using a larger kabuki brush to brush on faster but the brush it comes with works ok as well. It's the perfect amount of bronze and shimmer.. not glittery or over the top and doesn't have a smell. Doesn't transfer on clothes but I always let it dry a few minutes before putting on clothes.
