Does Op-amp Rolling Work? [Video]

[ssashton]

I dare suggest that most cases where an audible difference is found with an opamp change that either 1) Its imagined. 2) The new opamp is unstable in the particular circuit.

Take your aggression elsewhere.

And no, it was not clear in the least that your wall of text post was sarcasm. A /s would help.

In the context of this "hard-line objectivist" forum (to use a term from the quote), it should be obvious that any reference to subjective HS are to be construed as sarcasm. Warning that one has a "hair trigger for ad hominems" only to launch a personal attack with directives on what the other party should do is ironic as well. Take a valium, unless it interferes with your other meds (consult your physician).

OK, let's dial it down folks and stay with the topic of the thread.

Quite the opposite. 'Subjectivist' posts are common and are assumed, at first, to be earnest. There are exceptions. Usually they use humor to help indicate sarcasm.

In this video I "upgrade" the 57 cent op-amp in the Douk A5 stereo amplifier with a $49 one. Does it make a measured difference? Watch to find out:

Please subscribe to the channel. It is not monetized but like to make sure our voices are heard in the crowd of other videos.

I have the Burson Funk amp and played with their V6/V7 Classic and Vivid opamps. The differences are like day and night. Sadly, the Funk with technically best (V7 Vivid) cuts through my eardrums.

The differences are like day and night.

That can STILL be perceptive bias.

But if it is not, then it will be measureable as a significant difference. Possibly for example, the V7 vivid being unstable in that amp and oscillating

Last Burson amp i tested had serious performance problems including varying frequency response between channels: https://www.audiosciencereview.com/...urson-soloist-3xp-review-headphone-amp.34353/

You remind me that I also did OP Amp Rolling there:

Op-amp Rolling
I will do more extensive testing on this later but for now, here is the performance of the unit as it arrived with mix of Sparkos and Vivid op-amps:

This is basically the same as using JRC op-amp. Sources of noise and distortion are elsewhere.

Same outcome as this test. No difference.

BTW, forgot to mention this was video #100 for ASR youtube channel!

#100 for ASR youtube channel!

Nice, congrats mate, time to celebrate.

Danny Richie fires back today with a YouTube video:

Hell Yeah Rolling Opamps Makes Your Amps Sound Better! (Hear It For Yourself!)​

LOL, we're the flat earthers! I don't even know what to say to that.

Indeed. The projection is blinding.

As I mentioned before, when Danny did a video about the inadequacies of blind testing I commented, correcting some of his errors. He removed my comment on the excuse that my comment amounted to misinformation and he doesn’t tolerate misinformation.

Hello All,
last year, 2024, I did more than a little experimenting with Riaa pre-amps. I found that there are some differences among the Op-Amps of the world as a rule the subsequent generations are more the same than they are different, as most all can challenge the distortion measuring ability of most every audio analyzer.

To me the most me important "measurable" feature of Op-Amp performance is noise.

To me it is not so much about rolling OP-Amps as it is selecting the correct Op-Amp in the first place.

For an example, only an example. I purchased a Audiowind A-300 riaa pre-amp and measured several different Op-Amps in the pre-amp.

There was little to no difference in the measured distortion performance. Starting with the ne5532 and finishing with the OPA1656 the OPA1656 had somewhat lower noise. Not so much difference that you could hear it. For bragging rights If you are looking for the the last 0.1 dB on the SINAD scale go with the OPA1656 op-Amp.

Thanks DT

I didn’t watch it but quite a few comments from people who have analysed the audio samples and found them to at different SPLs. Also the music samples were labelled. The Sparkos op-amp was the loudest of the three music samples and was receiving high praise in many comments.

Someone commented that Danny and Amir are going head to head deliberately for views. Danny replied, “I don’t care what Amir is doing”

Yeah, I looked at the comments too.

It’s amazing how people are pointing out that you have to level match the volume, and Danny simply dismisses the idea “ trust me when you hear it at our place through the speakers it’s not about volume. It’s about detail and soundstage and imaging…..”

It’s hard to know whether he is perpetually ignorant or perpetually disingenuous.

Danny just finished doing a live Q&A on YouTube with Ron at New Record Day, and out of curiosity, I caught some of it.

They touched on some topics like op-amps making an undeniable difference, even talked about benefits of cable risers and some other stuff.

I honestly don't care whether you believe in those things or not, it's not a big deal to me either way.

What bothers me about Danny is how much of a narcissist he is. He is not humble in any way.

During the live, someone asked Danny a question regarding the Philharmonic BMR, and he talked about Dennis Murphy in a really condescending way. I'm paraphrasing, but he basically said, "We've tried to help Dennis out..." and insinuated that Murphy's designs have flaws due to his advanced age, and that he must have hearing loss, before ending it with "But I like Dennis"

What?! The BMR has garnered superb reviews and recently made Stereophile's Class A Recommended Components list for this year, but he needs your help?

I've noticed a pattern where he needs to put himself above other designers or reviewers as the authority on audio and that they all could learn from him. A couple years ago he released a video where he challenged all YT reviewers to travel to Texas (perceivably on their own dime) so they could learn from him. And he didn't realize that he was being a condescending jerk and played it all innocent that he was just trying to help when he received some push back from a couple reviewers.

Guy's a character for sure.

He has been doing this in every interaction I have had with him. He constantly repeats this as well. He thinks he is being smart with this approach. Pretend you are a higher level and people will just believe you. He is probably being successful at it. I remember Paul McGown also doing a bit of this toward me but as of late, he no longer is.

 

[MattHooper]

I think many visit Danny’s channel for their dose of passive-aggressive ASMR.

 

[DanTheMan]

It’s hard to know whether he is perpetually ignorant or perpetually disingenuous.

The evidence suggests he's perpetually disingenuous. He makes easily disprovable claims, uses tainted evidence to support his claim(s), extolls himself as the high priest of audio, and deletes comments that expose his lies. He's been doing this for over a decade that I'm aware of. I have a lot of screen shots on my hard drive as proof. I posted them in one of his underperforming speaker reviews here. He's an obvious charlatan, but the hive mind buzzing in the echo chamber won't explore new meadows. They just keep making the same mistakes over and over. They don't have over a decade of experience in audio, they have over a decade of the same experience in audio. I'm fairly certain that's why the forum is named AudioCircle. In his recent attempt at fraud, he tells everyone what difference he hears, labels the samples, and then has the ones he says is best recorded loudest. Then the Hive says "see, Danny is right! He's a supreme guru!" In a sense they are correct. He's a seemingly successful snake oil salesman in modern times when he's tactics are most easily understood and debunked.

What bothers me about Danny is how much of a narcissist he is.

True, it would be fun to see him in a cage fight with the Tekton narcissist, like the 2023 announced fight between Musk and Zuckerberg.
