Reddit mentions of Sound Appeal SA-100T 100W Class T Digital Audio Amplifier

I'm looking for an amp to use with my LP120 (with preamp disabled), Kenwood JL-601s, and Behringer Microphono PP440. I'm looking at these two:

Dayton Audio DTA-120 Class T Digital Mini Amplifier 60 WPC (Black) https://www.amazon.com/dp/B00HFG3FYA/ref=cm_sw_r_cp_api_mUhwyb0SYGDDC

I've narrowed it down to these two because I want something with an auxiliary port. What would you recommend? I've heard the Dayton has better build quality but the Sound Appeal produces less hiss. I'm leaning toward the Sound Appeal, but I'm open to suggestions.

Yeah I've been looking at the LP-2020A+, seems like a solid budget choice. Also this: http://www.amazon.com/dp/B00E8ONRBS?psc=1

A little more pricey, but also has audio in and headphone jack which would be hugely convenient for me. What do you think?

The best computer speakers aren't computer speakers. Instead, look at home theater components and small bookshelf speakers - no matter how fancy Logitech's speakers look with swoopy plastic, they still can't compete with a big rectangular MDF box.

Personally, I use and swear by the Audioengine A2+. They're tiny, with an integrated amplifier and seriously impressive sound for the size. If you have the desk space and want a front volume knob, their larger A5+ will give you more bass. Pay attention to the dimensions, they're pretty big. Neither of these will quite match the bass of that big Logitech subwoofer, but their overall sound quality is superior.

You can also do passive bookshelf speakers hooked up to an amplifier, with or without a separate active subwoofer. These could be inexpensive speakers from a pawn shop or garage sale, or a set of new ones from Best Buy or wherever. There are holy wars fought over this stuff and many opinions on the internet about what's "best", but the truth is it won't matter. Even some inexpensive Polks will outclass the Logitech system. You might even be surprised at how good a relic from the 70's sounds, particularly if they're big and have more than a single speaker element.

Now, the Audioengines are good to go right out of the box, but for passive home theater speakers you'll need an amplifier. You could use a home theater receiver, but probably don't have the space for that. Instead, look for a small dedicated amplifier like the very-popular Lepai. I've also been pleased with Pyle's small amps, and you can get a bit more power from them, but the signal-to-noise ratio at high volume isn't the best.

Edit: If you want EVEN MORE amplifier power, I've also read good things about this Sound Appeal amp. Actually, from the reviews I'd say it's a lot better than the others, but I have no firsthand experience. It has more power and less distortion. Definitely worth considering.

Big 3-way full size bookshelf speakers, excellent value.

Somewhat pricy compared to other entry level amps but excellent value. Delivers a lot of power and will last several speaker upgrade cycles.

1. Metal works great - if it's sufficiently well braced. 3mm steel with a lot of internal bracing (little triangles in the corners will go a long way) is plenty strong, and while you'll want to coat it with something to prevent ringing, it should work pretty well. That said, it'd be a huge amount of welding - MDF is a lot easier.
   
2. Upgrading to an amp like this would be a worthwhile upgrade. Alternately, buying a Sure Electronics amp board for cheap and building your own amp enclosure would be a great use of steel...

This appears to be a clone of the Dayton 50wpc which had very "meh" reviews for reliability but it does fit your budget and stays small and 50w.
