PPI vs. SoundStream

[SofireGuy 10+ year member]

Alright... my dad told me that soundstream has always been a great Amplifier company... i've been more into the Power Precision Comp series amps... but i came across a couple of Soundstream amps that have pretty much the same exact specs but at a better price.... check it out

Old Soundstream used to rock, but once they went under and came back, they haven't been the same.

PPI used to be sweet too, but I have no experience with the newer stuff.

So do you think that either one of the Soundstreams are worth it?

The Soundstream Tarantula's are good amplifiers. Those new Ref's look interesting, but I don't think they've actually began shipping yet (and from what I've heard, they won't be available for little while yet)...so it's hard to say how they will be.

So, I would narrow your options down to the Tarantula and the PPI. And out of those, I would personally take the Tarantula.

Here's a good tid-bit of info about the new Ref's though: http://www.diymobileaudio.com/forum/showpost.php?p=24659&postcount=44

Maybe look into the Van Goghs as well. Mine has been pretty solid so far but I have always been partial to Soundstream //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif

The VGA's are indeed good amplifiers aswell.
