Modding the PS Audio Directstream DAC MK1 and MK2
Attached is a sweep of the LUNDAHL LL1948Ag (silver) transformer for comparison. These transformers are some of the best and most expensive units made however are not that good in the DS.

That may be true however without the Vocm mod and our nickel transformers in the MK1, it’s not a fair comparison. We have both the fully modified MK1 and the MK2 with our transformers, the input grounds fixed and 3M RF shielding setup to do instan...

Here is an FFT of our modded MK1 with our nickel transformers.  Much better than the stock unit and the new MK2.

The weird thing is we have tripled our sales since leaving the PS Audio Forum and opening the website.  Should have done this a long time ago.

Below is a Post by Elk on the PS Audio Forum. He can’t even be honest with the forum members over there. He knows I can’t post on the PS Audio Forum to correct false information. He did in fact delete any post that praised our mods and / or post ...

I don’t recall us making them exact statements. The Custom nickel transformers do in fact increase the output level by 6dB because they are and were designed as a 1:2 transformer instead of the original 1:1 transformer that are installed in the MK...

Unbelievable... It took PS Audio forum members over a week to discover and discuss this problem after my post exposing this issue was deleted by Elk. The ones who have the tabs missing or loose... This is not an easy fix as they rip off the copper...

PSA just posted their measurements. Yes they did. SINAD at best would be 70 dB. Same as what we posted last week when I was accused of posting bias measurements and badmouthing PS Audio.

Why don't you ask for the manufacturer to show measurements that demonstrate otherwise? If manufacturer can't or won't do that, then that is that and independent data remains as authoritative.

Another funny post from PS Audio forum: wudai_e 4h Also the thing with measurement, If I have a predetermined bias before hand, I can make the measurement results to support the said bias. I’d take any audio measurements with a huge grai...
