Finally finished up my second LM3886
Chipamp build. My objective was to create a solid state amp that didn't look like a solid state amp, to get away from that idea that SS amps are just big black blocks with heatsinks. In this case I hid the heatsinks on the inside and positioned the toroids out of the main chassis to give a more vintage, tube-amp like look.
Chipamp PCBs, DIYAudio Soft Start board, and
Cardas wire and connectors are used throughout. Kilo knobs adorn the front, and Antek torroids and torroid shields sit on top. The chassis is made by
Horace Atkinson of
www.iagaudio.com, VERY solid .125mm aluminum with figured maple wood accents. I opted to finish the maple my typical red stain, but with a glossy finish this time (took quite a few coats). The chassis and shields are powdercoated for a nice durable finish.
Additional parts include 100uF Clarity Caps w Sonicap bypasses, Elna Silmic electrolytics, Nichicon power filter caps, Wima PP film caps, Audio Note Tantalum and Takman film resistors.
Ended up being a nice tight build with little wasted space. Features 5 inputs and subwoofer output, the wattage output is (I believe) ~68 watts. Sounds very nice, a bit more refined and "present" than my previous attempt. I'm sure the film caps and separate power supplies have something to do with that. Still presents a mildly warm, natural sound with a bit of emphasis on the top end. Compared to my everyday integrated, a Manley Stingray with upgraded tubes, the sound is a bit less emotional and loses some midrange liquidity, but is more crisp and detailed with a bit more force. We'll see if anything changes with burn-in. I'd still recommend this as a nice SS to try for people who usually only listen to tube amps, as it doesn't have that clinical sound that some SS amps possess.
