Amplifiers
Unit comes with a NJM4580D or JRC4580D Op Amp
Suggested: LM4562NA Dual High Fidelity Op Amp
Or: OPA2132 FET Op Amp
The 4580D is a general purpose mid wattage amplifier with a good overall sound;
The OPA2132 is a mid wattage amplifier with cleaner highs, muddier lows;
The LM4562NA is a high wattage amplifier with the broadest range of fidelity (frequency) and lowest SN Ratio (Noise, THD), also the most expensive at $5.00 each (avg).
NOTE: Although the SoundBlaster is listed as a competitor, please note that their 192KHz sample rate is stereo only, it is much lower (96KHz) for 7.1 (even their best card) but, they are the closest for specs to this card. This is a very big difference between them.
