Have you heard the Sprout100?

Hazsve you seen the crazy video of Scott driving the Infinity IRS-V's with the Sprout100? Lol, but gotta say it held it's own.

i heard the sprout 100 recently and i gotta say it's a very impressive piece of machinery for $599--even the bluetooth sounded good. did not seem underpowered at all--the all-in-one functionality, small form factor and clean design should satisfy 99% of folks out there.

I have not heard the Sprout 100

I have BEl Canto C5i which is a wonderful unit also.  I wonder how these two compare?

$2,000 vs. $599.
Made in Minnesota versus "Designed in Boulder, Made in China"
Having never heard the Bel Canto, I am going to lean in that direction just based on the price.
The Sprout100 has a Bass Boost, which helps if you don't have a sub-woofer. But even with Boost, I find the Bottom-end a bit on the weak side. The Sprout detects you plugging in a sub-woofer, and shuts off the Boost. That tells me that you really need a sub. ICEedge technology has really exploited the Class-D amplifier chip.

The bass boost? truly an awful (for me) design feature/fault. Does have some good features for the money though. Floor standers, Death Metal, and a sprout, a marriage to torture the ears, lol........

After a good burn-in, the Sprout100 has come into its own place. Very bright, with plenty of headroom on dynamic pieces. Bass Boost needed without a sub. Really sweet "Swiss Army Knife" of Integrated Amplifiers.

to bring folks up to date. I was given an Infinity Intermezzo 1.2s subwoofer and I purchased a length of Audioquest Black Thunder II subwoofer cable. That completes the sound to the extent that my friend from the "Class-D just isn't There yet" camp didn't even utter "class-d" when he heard the Sprout100, with sub.
