Atoll IN100 Signature Integrated Amp, $2100

(100×2, Class AB, Dual Transformers!)

We all know the Middle Child sometimes gets lost in the shuffle. It ain’t fair. Well, maybe it is in YOUR family, but not in the Atoll family.

Atoll is made in France with a 3 year warranty. They make five integrated amps below $4500 and each is a stalwart of excellence at its price point.

IN50 Sig, $1200 (50×2)

IN80 Sig, $1700 (80×2)

IN100 Sig, $2100 (100×2)

IN200 Sig, $2800 (120×2)

IN300 Sig, $4500 (150×2, comes with built in DA200 board)

Given that we all work for a living and want the best value for our dollar spent, it’s pretty logical that Atoll’s middle child might be the place for you to start when building out your hi-fi. Spending heavier on speakers makes sense if you have to parse out your investment.

All Atolls are dual mono designs. IN100 Sig is the first model in the line to feature TWO massive, 340VA transformers. Its two little brothers run single transformers. I’d like to get you into a pair.

The sonic advantage of running a pair is… the pair delivers a uniquely more muscular sound. You can’t miss it. This is an advantage for more than loudness. It gives more weight to a cello, piano, drum kit and even the human voice.

Since the next amp down in the line, IN80 Sig, runs $1700, I’d like to twist your arm to step up to the middle child, IN100 Sig for $2100. Given Atoll’s formulaic build ethos, all $400 you’re spending for the upgrade goes into the GUTS of the amp and is well worth it. You’re not buying nebulous features. IN100 Sig has almost 32,000uF of filter caps to deliver rich, muscular sound. Most 200w amps don’t run a pair of transformers or have caps this big!

IN100 Sig can also be expanded with Atoll’s build your own pizza game plan. At $2100 you get IN100 Sig in LINE STAGE configuration. That might be all you need.

Atoll offers the P50 MM phono board for $130.

Atoll offers the DA100 DAC board (2 coax & 2 OPT) for $300.

Atoll offers the DA200 DAC board (2 coax, 2 OPT, USB & Bluetooth for $500).

If you’re spinning CDs, please consider an Atoll CD player as well. They’re significantly better than the flimsy Chinese offerings due to multiple linear power supplies and big filter caps. Atoll runs Burr Brown DACs in its CD players with no negative feedback. They sound warm and mellow instead of thin and grainy. We can show you the differences, convincingly, here in the shop.

Atoll makes two bigger brother integrateds.

IN200 Sig ($2800, 120×2)

IN300 Sig ($4500, 150×2 which has built in DA200 board).

We luv em both and if the money doesn’t matter, sure, consider the bigger brothers.

As we look at bang for the buck performance at about $2k, IN100 Sig stands alone. Literally all of its competitors are Chinese or class D designs with a thinner sound.
