Hi, normally, I don't use Op Amps at all. But sometimes, there's no other way, so I made a comparison between 4 op amps
Sparkos Single OP AMP
I'm shure, that there atre better IC Op AMPS on the market, but that's all I had.
And now, I did not listen to op amps in the audio path, no, I just wanted to know, what happens, if you replace a comparator IC in a voltage controlled current source that heats my tubes of a preamp.
I was very surprised, that you can hear the results as they were in the signal path...
The AD797 sounded even worse than the comparator. Dull small ect...
The BB 227 was a little better
The Sparkos was so much better, open, strong, another planet
So were the Bursons. But they were even more open. More stage, more Details. wow. The V5 sounded brighter than the V4, which sounded brighter or opener than the Sparkos. So with the choice of the op amps, you have a tremendous influence on your sound. It just depends on your environment and your taste. I cannot say if bananas are `better than melons`
Go and find out.
I can only recommand to make own listening test, the difference can be big.
