Purchasing and changing OPamps on Titanium HD.

post #1 of 2
Thread Starter 

Where can I buy the best ones and how do I install them?


What difference will I hear with headphones? I am going through Optical, Audio Creation Mode, 44.1 kHz, Bit-Matched with Audeze LCD-2 Rev. 2, V200 amp, and Rega DAC, and gotta tell you, it sounds damn good. Heavy bass and such. Could it actually get better?

 

I don't want to change the sound, just make it more refined, if possible. I am also looking at Lifatec Toslink cables.

 

Thanks. smile.gif

Okay, the dubious "benefits" of op amp swapping in most situations aside, if you're using the S/PDIF output, the sound isn't going through any of those op amps. So there's actually no** difference here.

**Well okay, different op amps may have different quiescent current draws and so on, and could put a marginally different load on the filtered output of the power supply rail, which could marginally change performance of said power supply rail (if the analog and digital sections are using the same rails, or if they're not and there's still some slight coupling), which could marginally impact the behavior of the chip handling the S/PDIF output, marginally changing the jitter of said S/PDIF output, which possibly introduces a kind of distortion on the D/A on the other side with most S/PDIF receiver implementations.

Usually there's just no audible difference swapping op amps, or if there is one, it's going to be worse than default. And often people are swapping op amps on devices they're plugging headphones directly into, when it's the headphone output stage (generally not socketed) or the design in general that is the limiting factor.
