HOLO Audio MAY DAC

[firedog]

Where is the May actually available? Or is it? I can't find it online.

Don't think there is one. That's why the obsession over Sinad by some is ridiculous.

I think high Sinad is probably a sign of good engineering, but it's not a guarantee of much else. After a certain point it doesn't mean much.

But in both sets of graphs it looks like the noise is mostly 120 db down. Is it audible at all?

I might have a track to suggest to illustrate and for everybody to try : Fever on Elvis Presley's Elvis is back.  If I play PCM (from the DCC CD) I can follow good ol' Michael Fremer who hears finger snaps, more or less fleshy depending on he used a 450 000 or 560 000 $ turntable. If I go 256 7EC (and even more so if I source from the AP SACD), Fever's rhythmic sounds like the 2 parts of castanets are hit one against the other : distinctively sharp, quite dry and woody to my ears and unmistakably (or am I mistaken ! wonder what you guys will report !) so and not finger snaps. Now I confess I had not tried PCM 1536 for weeks and I can understand how it might be judged more palatable and rewarding, especially if one's system does not involve convolution : felt like lowering volume when going from PCM to SDM, as if adding 6 dB to SDM was too much. BTW, I love Closed Form 16 M, a new favorite provided apodizing counter does not go berserk.

I just listened to a 24/96 version of that track and it sounds like finger snaps to me. Acc'd to the Wikipedia album page, it's finger snaps. Interestingly, when I use HQP to play it back in DSD 256 7EC, I'd say it sounds less like finger snaps (less fleshy, more hard/sharp), but I'd still  identify it as finger snaps if you asked me.

I can testify that this works.

You can try this :

 

Or this :

Simply... Putting distance between electrical appliances that can pollute each other.
(electric field decreases with the square of the distance)

If it's DC on the line that won't help. It can even be coming from a source outside his home.

Please tell me, did your holo make noise from day one or did it start making noise after a while?

Don't have a Holo. It was with another device. It wasn't from day one. DC offset is usually something that comes and goes. But it doesn't matter. If you have DC offset on the line, the device helps.
