Purifi Class D: Junk?
djones51"My theory has already been tested, none could tell a difference. Better luck next time." My English suffices for me to detect this an an insult, which is the type of response we could expect from someone who makes a broad, sweeping, over "arching" claim for which he has no proof, substantiation or references and which reflects an underlying inability to comprehend or understand the actual topic under discussion so as you say "Better luck next time" if you want to be accepted as an authority or expert. |
I never said I tested the theory. I see no reason to educate anyone on sighted bias. The only way anything claimed about opamp sonic differences is if they were tested in a proper controlled blind setting. Flowery subject anecdotes while highly entertaining gives no valuable information. Thanks for playing. |
@djones51 - if you don't trust your own ears and your ability to overcome sighted bias, that's fine, but telling everyone else that they are wrong is pretty arrogant. In my past experience with the Nord Hypex NC500 monoblocks using the Sparkos and Sonic Imagery opamps, the differences were pretty obvious. Once both were well burned in, I switched back and forth a few times and had a couple of friends over to listen as well (who didn't know one from the other). The Sparkos opamps were smoother and slightly warmer sounding, but clearly lacked detail relative to the Sonic Imagery parts. So far, I have only heard my Purifi amps with the Neurochrome buffer board which uses integrated op-amp chips (not discrete). There are pros and cons to both (IC vs discrete), and this is probably not the proper thread to discuss those. But I would like to hear how my amp will sound with different buffer designs and will eventually give one or more a try. |
