Buckeye Amps: Hypex NCx500 Official Thread

[Doodski]

Micro Audio does really nice, quality work.

If Micro Audio power supplies are in the upcoming integrated amp(s) then wowowow!

You thinking available by X-mas? Early '24? Help a man out, here D! I gotta budget for this, after all.

Cheers!

I am very hopeful available before Christmas. The production run normally takes 8wks but as I said, we are doing a few things to speed that up.

Definitely missed the early eta of Q3 I had hoped for. But in the end it is better everything is tested and working perfectly, of course.

Here is the first 3ch NCx500 build. The SMPS is very beefy.

Looks magnificent! I didn't know the extent to which a switched mode PS needed power factor correction -- but apparently it can, and in spades. Learn something new everyday. Speaking of power efficiency, will this SMPS idle low, or is that a future change for all of the various models (and essentially independent of the PS)?
Good luck on the builds!

@ David

SMPS2K will idle at 0.2W in standby mode.

Thanks

Not stand-by,idle,these are two different things.

 

[David C. Navas]

Not stand-by,idle,these are two different things.

Well, they are, although in this case I meant stand-by (specifically, waiting on 12V trigger).

I had missed MicroAudio's August 14th post (https://www.audiosciencereview.com/...urifi-amplifier-review-2nd.43834/post-1687013), or if I read it I didn't make the connection -- my apologies for the repetition AND the imprecision. Now I have to decide if I want the rackmount option or not

 

[Buckeye Amps]

We are making a few final modifications to the official SMPS' for production. Mainly the addition of a robust heatsink and thickening of the baseplate.
But testing shows the SMPS is doing what we want: fully driving all three channels to spec.

Hi Dylan, I wanted to know if these power supplies will equip the two-channel amplifiers and the new integrated amplifier. Thanks

This exact power supply, no. At this time only the 3ch NCx500 and the Mono Purifi 1ET7040SA v2 are going to be using Micro Audio SMPS'

 

[GiFi]

So, maybe a variant of this one? And when? Thank you

 

[Buckeye Amps]

We have been testing a variant of Micro Audios current SMPS 1k, but one that would support multichannel. It could likely become either a replacement for all Hypex SMPS' we use or at least an available upgrade.

But that won't be something to come to fruition until at least the new year. The 3ch NCx500 is our first priority. Then the Integrated amp. After those are out in the wild, we will revisit.

Also standby is more relevant for an amp that has auto-on and off. Idle is going to depend more on the load (in this case the NCx500s). Hypex spec says about 6 watts per module. So know it is already at least 18 watts. Could measure the test unit but is not final production so will wait for now.

Here is the first 3ch NCx500 build. The SMPS is very beefy.

I have one last round of testing (sending off to Rick for an ‘independent’ testers stress testing as well as mine). But the full production run of the SMPS will begin shortly (some major components are already ordered to help save time).

Are there any plans to use the larger power supplies to make Purifi 1ET400A amplifiers with a greater number of channels (than the 3 currently offered)?

Maybe down the road, but it is not on the immediate list of evolution for our product lines

How many channels do you want and what is the use case?

 

[ryanosaur]

11 channels, 1 chassis.

[Buckeye Amps]

I hate saying no to customers but as most have heard me say before: spending the money on Purifi/NCx modules for speakers past either a 2ch or 3ch LCR setup is not really worth the price difference over say the NC252 or NC502.

I yi yi... You would require 2 power cables for that boy.

Oh, and they would all be mono block configuration!
