This is interesting. Will you keep us posted on the outcome of your efforts in terms of successful strategy and equipment used? I am also interested in conducting response measurements and would hope to participate in your realisations.

That is a good question, actually. In my own listening experiments, subwoofers are more about room positioning, phase alignment, and exact crossover integration with the other components of the system than size. At least for the purpose of audiophile listening, smaller diameter woofers will be...

Some of the world’s most profitable speakers manufacturers design no-linearity into their products to beat the competition in the showroom. Not in HighEnd so much where people will insist on auditioning at home.

Come on, it happens all the time. The unit that was the big winner in the auditions turns out to be the loser at home. Great sound effects are often a great bore in the long run.

Our systems cost money, so we might as well enjoy them. Since it is audio equipment, the joy of listening is a substantial part of it?

Yes, I get that. However, A/B comparisons can fall short of the WOW-factor. My biggest indicator of success is listening over time. I stick with the version that gives me greater pleasure over time. Ear fatigue is a good indication that something is not yet right.

Ear over brains. The audiophile motto. 100% with you.

I had no intension to deflect. High frequency interference coming from the grid will lead to an audibly poorer performance of audio equipment while they are pre-power supply. I have installed a parallel noise eater and ferrite clamps on the power cables to less the effect. The result is better...

Listening enjoyment without stumbling over tonal imbalance does not qualify as 'the basic experiment'? How else should I determine my success in setting up a system, if my own ears cannot play a role in this?

Thanks. I'll have a look for it.

Good point. It could be from the difference in available power to the DAC that the resulting musical output supported by the linear power supply had a better deep end and was less leaning towards hash and bright.

Well, I guess you are familiar with the effects of EMI on power supplies and the traceability in music, right? This would be such a case in point.

Have you ever measured the noise on a components power rail? No, I have not. I am not experienced in conducting measurements myself. The only measurements we conducted were with my engineer friend on the power distributor strip. He himself doubts the effects of such interference on music much...

Interference to the power line does not come out as this same interference to the signal, agreed. However, it does influence the equation that is to be music. I have learned that great setups can make gear invisible. If we get to this point using a DSP, all is OK. But we get to this point...

Yes, I can see that you guys are leaning toward the scientific. Most of my friends are too, and you can imagine that we have long nights. ;)

Both the Parasound and the Adcom look great. Adcom had a good name for budget gear that punched above its weight. Would you recommend the NAD? I have yet to purchase a decent network streamer, but somehow I still prefer to put the media on by hand. I have tried Tidal and Amazon HD, but I get...

OK, now I get the title "Audio Science Review". It has to be measured and not heard. But when it can be measured, such as the interference from a power supply, you claim it cannot be heard, right? Well, go figure.

Yes, well that could obviously be said for the both of us, coming at the subject from opposed directions. Since the subject was on vintage amps, I got interested. I did not anticipate to be blasted with DSP and digital transformers. What is your current gear, I wonder. And what would be your...

Many roads lead to Rome as they say. You trust your alterations to the signal are great and noise should not matter theory and I trust my signal integrity because noise does matter theory. Your system won't sound any better by convincing me. As long as we're both happy, what's the problem? I...

Cool...! Thank you for sharing. I have never seen an image of them placed side by side, although the power supplies are not on top of the correct unit, as I have the bottom left amp with the top right supply, but perhaps there was a change in production. The subject of tone controls is a bit...
