Please write them in a raw starting from the best sounding. Explain the good and the bad of each one you tested!

What type of load are you driving? Headphones or is this going into an amp? If it's driving headphones I might understand this possible rise in output since it is a harder load to drive vs an amp that has a typical 10Kohm input impedance. The PSU voltage does not change so really you are still capped by the PSU rail voltages going to the opamps in the buffer circuit.

sorry im no opamp reviewer.. the only opamp reviewers should be the artists/the ones making the music, everybody else is just stating their subjective opinions

sound is very subjective.. heck even video..

there is no good/bad about the highend opamps.. the differences are more subtle

it also depends a lot on your sound system/gear

if headphone i wouldve stated

no amp/receiver/etc.. just wires between the sound card and 7x powered subwoofers - 1 front left/1 center/1 front right/1 rear left/1 rear right/2 main

believe it or not my modded MX300 beats the crap outta stock prodigy

2x 2200uf paralleled power filter

NapalmV5 · 04-22-2008, 04:47 PM

since CE22 & CE39 are @ 5V.. ive replaced the 2x black gate 4700uf 16V caps to 2200uf 6.3V BG NX for increased capacitance & improved sq

too bad the prodigy doesnt have an LFE.. this would be the badest sound card around

dbDRAG · 04-30-2008, 01:08 PM

Just bought a brown dog adapter and fitted 2x lm4562!!!!
Nice sound...BUT the opamps are REALLY REALLY HOT!
I put back the single

I do believe there is LFE on the prodigy but honestly I have not used it as a surround sound card so I'm not 100%.

The pure fact that is has Directwire allowing you to use VST plugins makes it a killer card.

Forget traditional 5.1, go the VST route and enjoy the benefits of ambiophonic and ambiosonic processing through VST.

Once you go that route, little electronic extra "SQ" gains to improve accuracy is far-outweighted by the acoustics factor. I know, I was once there but I have realized the real problems are limited by acoustics and no longer electronics, especially the problems/limitations with conventional 2 channel stereo and even commercial 5.1.
