"Echo Indigo IO is way more better than this card"1.5 starson by audiomaniac
Pros: Direct 5.1 Surround connection ability.
Cons: Sound quality far inferior to Echo Indigo IO
Summary: I basically listen with a headphone from my Laptop. I use a Grado SR325i and though not quite satisfied, I was happy with my Creative ZS >> Until I heard the Echo Indigo from my friend.
The difference is not subtle at all. Its in fact so much pronounced that even a half deff guy could say the difference. With Echo Indigo, you get pristine clarity in the higher frequencies (crystal clear treble), accurate and eye-blinking Bass and most importantly, a much greater depth to the music. I was literally astounded with the difference, never thought that the laptop could sound so good..
This could possibly be because the Echo Indigo has a built in DSP processor along with an extremely superior quality Headphone Amp that really exemplifies and spatially separates the vocals from the guitars from the drums etc. On the creative, the sound is just flat and really muddy when compared to the Echo Indigo IO.
All said, the Echo Indigo is more expensive than Creative, but I still strongly and wholeheartedly recommend it over Creative ZS.
As for me, I received my Echo Indigo IO a week back and my Creative ZS Notebook is up for sale on EBay
