Yup! REALNESS factor just jumped up another notch.
 
Is there any end to these improvements? Hahahahaha!

That's a really good question and one I don't really have an answer to.
 
We keep finding more and more CP's and once they get dialed in the SQ keeps getting 'better' and 'Better'.
 
It does raise the question of how much 'better' can it get though, doesn't it?
 
Right now my heads on a swivel and my body is mov'n to the music while I sit and type this.
 
Way Kewl.

So I'm almost done with my write up (with pics and measurements) of my latest LPS implementation/build.
 
And I must say that as this latest tweak settles in I am hearing more and more subtle and some not so subtle shifts and changes to the SQ.
 
Gone seem to be the extreme swings of SQ as things settle in, from really great to ho-hum to TD (Toilet Dump).
Now its T3 and HB&W pretty much all the time, well unless I'm mesmerized, or break out in laughter, by what I'm hearing.
Along with these new degree's of REALISM and SUPERDUPERGLUE, I still have 200+ hrs before the metallurgy peaks followed by the 2 LPS transplants etc.
 
Yeah some fun now, lemme tell ya.

And gefski have you looked into a LPS for your uD0 yet?
I would bet that you will be as amazed as the rest of us are, with the results we are hearing.

Adding an LPS to the Attero Tech unDAES-O is quite easy given the single supply 24V DC input. This one works very well for not much investment:

I keep looking at Acopian. Great looking stuff, U.S. Mfg, and atomicbob says those folks are really good. But you know I take my time on changes.

...and I keep looking over my shoulder toward California, afraid Mike Moffat is going to release his hinted at super duper isolated USB interface, ruining our Ethernet fun. :D

Hmm...plug and play, affordable. Thanks for the link.

I really like the look of Acopian, but it's not plug and play, more expensive.

I'll waffle around a while and discover more music. :wink:

This http://www.ebay.com/itm/100VA-Ultra-low-Noise-LPS-R-core-Linear-power-supply-DC-5V-24V-With-display-/131867485038 is what I am using to power up the Mutec MC3+ usb. If you read the tech specs, it is All-discrete topology - No IC (integrated circuits) are used - Low noise, high PSRR - and the output noise (unloaded) is less than 13µV at 24VDC output and it uses a very robust r-core transformer.
 
I'm waiting on 2 more of these, 1 @ 5vdc to power up the 2 Mutec non-usb and 1 @ 17.5vdc to power up the Antelope Live Clock. A little bit more pricier but if you look at the internal shot, you'll see that it is really well built.

What method to power 2 Mutec's from the single LPS?

You can use this y-adapter https://www.amazon.com/gp/product/B01GPRLQCC/ref=oh_aui_detailpage_o00_s00?ie=UTF8&psc=1
 
Note that this is for the 2 non-usb Mutec's that is rated at 5vdc input. That LPS link I posted is rated at 5V/6A so it is more than enough current supply to handle the 2 Mutec's.
 
Heck, it can even power up 3 non-usb Mutec's.

I have that LPS already. Just didn't know if you were going to use y-cable or modify the LPS itself. Please let us know how it turns out (may influence my next purchase). Thanks.

I am already using that y-adapter on a Jays Audio 5v lps with good results but the specs on the MeiYAN LPS is even better and the LPS itself is more robust than the Jays.
The Jays really get hot when powering up both Mutec's and is only rated at 5v / 2A.

I have a Jay's too. It's the one with the dual DC plugs on the back (set to 9v). I run two FMC modules off it, no issues with heat at all.

IMO the Mutecs consume more power and current compared to the FMC modules that is why the Jays really get hot. U can fry an egg on top of it.

I'm guessing, but I would suspect your Jay's LPS is 5v/3.5A
 
Someone posted what they thought was the SMPS being used by the Mutec as the following:


 I would assume it's the NFM-15-5, rated at 3A. Not sure what the Mutec is actually pulling, but they could be getting close to 3A when combining them.

The one i got has a DC out socket and a USB socket. It is rated for 2.5amp max.
