Hi,
Yes strange, but when you want to know major differences, I adopt the same system, quickly turning the balance in mono.
Customer has made the first tests, only the high band...
we should ask him if he listened difference in this case

Hi every one!!

I can see my amps!! Since Im running active speakers and want more power on low frekvensis I thought I might try AP powersupplys on N-core.
I started out to see if there were any nastines,, so I tryed it on treble
first..
And it just blowed the hypex smps of the track..
More air bigger sound stage with far better
precision ,,,and the pace rytm just flows,,!!
Im impressed,,looks like i need 6 more of these..

Mats.

Good Morning guys,
Ciao Mats,
I really appreciate your posting completely natural.
In this 1.5 years, only 4 people have talked about the DPS-500 in forum, (for me it is a mystery), especially in Class D, where there is no magic NFB, which can clean up the harmonic content, totally artifact by conduction via smps.

Regards

Thanks Danny, I recommend making a list, if you're interested, as I have already said, this version is only available in 25pcs.
For the first-one, mates excellent in all conditions.

I have been at Mats house two nights in a row now to play this fabulous power supply. I find it hard the describe the improvements over smps 600 in words. The only thing that comes to mind is that it simply plays music!
This is a older picture of mats system:

The Ncore powered by the Audiopower power supply is only driving the treble.

@ Yman: I appreciate your time spent listening, I hope that others can hear the differences offered by this smps for audio.

Info:
From 01/03/2014, customers who bought the shop to APower, who received this version.
is the new version of the Power-Unit, just to align with the DPA-400-Fxx.
Another novelty, that all smps, including the "magic" DPS-400 will mount the set Nichicon Audio-Grade, on all DC outputs.

and..., just out of curiosity, two companies in the field of high-end, in the range 150-200w per ch (A-B Class), after extensive listening tests, and measurements (6 months), have agreed to use the compact DPS-400 into their products.
The audio measurements, and listening tests, has passed the transformer with 2x47000uF. of course, they sent all the measurements, so they can be available.

The DPS-400 was equipped with 2x9200uF total, of Nichicon AG.

well, every now and then ... good news

This version of the "DA", dedicated to the first one amp also, the savings is about 65 , complete set including Nichicon audio grade. One problem...in case of gb, i can offer only 25pz D/A version., others qty available on AudioPower shop.

Regards
You can only offer 25 pieces of D/A deal for the First One? I sure hope I'm on that list Roberto!
