I ordered it on Amazon to use for my home PC setup...Most of the mini-amps in the under $50 range were only 2.0 (no sub out)...

I am completely blown away by the sound it produces...I have it hooked up to some Polk Audio R150 bookshelf speakers (from Frys for $49) and an Onkyo HTIB 12" powered sub...

For the past few days, I have been using an old Onkyo TXSR605 receiver just to 'test' it until the Class T amp arrived. I wanted to replace my computer 2.1 speakers (had some awesome 2.1 Altec Lansing speakers that were about 12 years old that started acting up which were replaced with some refurb'ed Klipsch 2.1 speakers on Amazon that were great for about 2 months but the sub started to rattle/buzz at medium volume)...

I had the Onkyo AVR connected via optical cable from my PC which sounded better than the regular stereo plug. I spent a few hours tweaking the Realtek Audio HD settings on my PC for both analog and digital settings on the PC and I could never get the analog out to sound as good as the digital out. The Orb amp holds its own and then some against the Onkyo.

The only downside is that the RCA input for the sub is pretty tight so it only accepts a 'regular' tipped RCA cable. I have some upgraded RCA cables that I normally use but it doesn't fit.

Here is pic...cable on the left fits but the one on the right doesn't. The cable is barely tight enough so it won't jiggle but I would be happier if it did fit more snuggly.

Overall, I am very happy with the sound (even just using the stereo plug output) but disappointed with the sub input connection. It is still definitely a huge upgrade in sound over my previous PC Speakers setups.

The only other mini amp I considered was the Griffin Twenty.

This was $30 more but has an optical input (the only input for this device) so I am wondering if digital sound would be any better. In any event, I am okay with the Orb amp for now.

nice. i've been using a topping tp21 for the past year with great results. the sub output would be really nice to have though! my sub is running straight from the soundcard, so I have to use software volume adjustments to keep everything lined up.

Picked up a polk audio 10" sub on Black Friday for $70...OMG the difference between this and the Onkyo HTIB sub is night and day....The sound coming out of these speakers is insane for a PC setup :)

Wait til you upgrade to one of these boys:

I just keep slowly wanting more and more.

It gets addicting man.

I started off with a logitech surround sound system for $300 dollars which was GREAT. But each upgrade has made me realize just how much more there is out there lol.

The logitech sub is similar to your polk audio sub (maybe smaller/a less range), but then I upgraded toa $300 Kliipsch Sub and was blown away. Now I have a DIY project in the works that I need dto finish with a 15 inch box.

Hopefully this setup keeps me happy for awhile...That crown amp looks pretty sweet but is definitely overkill for my 12' x 12' home office room...hell the polk R150 bookshelf speakers and the 10" sub is overkill...LOL
