JS-2 Power Supply Installed!

Just my experience from the JS-2.

 

I have bought a used JS-2 and I have ordered to Uptone a MMK and Regen I am waiting for.

 

For the moment I use my JS-2 to power my lan switch.

In fact, I did that to test but didn't expect to get better sound.

I was wrong, I was very surprises how the JS-2 powering a Lan switch could improve the sound.

I get more basses, more air and all seem more defined, specially the human voices which are more detached.

A real surprise for me.

Next step, use the JS-2 and MMK. Hummmm !!!!

you'll be amazed! ;)

 

just got an HD-Plex (sorry Alex: can't afford a second JS-2 at the moment :P ) for my NAS and, as it didn't came with the right DC cord for it (but it's on its way here), I'm using it for the ethernet switch between NAS and Mac mini: it does make a difference indeed! :)

Guess this is why using a NAS with an ARIES is an advantage.

My Amber is on a day off.

I installed in my Uptone Audio MKK on my Mac Mini.

I plugged in the JP-2, Played the music and was a tad disappointed with the overall change.

Ran the LPS and the MKK for a week more and what a revelation.

The biggest gain has been that my system has lost lot of the Ground Hum that I had...I dont know why.

As my Preamp/Power Amp and DAC are all tube based, I assumed that somewhere one of the Tube was screwing the harmony up.

BUT now! what a revelation....I had secretly been listening to my Headphone rig (;)) more and more due to my personal disappointment with the final sound that my rather expensive system produces......Now it would be interesting to get the Regen on and see what this does to the music bloom!.

 

So ground loop issue sorted.

Sound with depth

High frequencies now more tight

Low frequency has a certain clean ring to it and the mids are lovely too.

So at present it seems lie every thing JS and Alex produces is gold dust!

Today I experimented with replacing the Auralic Aries LPS with an Uptone JS-2, during an audition at a colleague's place. The Aries drove a Vega DAC over a coax digital cable. The Vega was set to linear phase filter and Exact clock modes. A total of 5 people were in the listening room. After swapping in the JS-2, everyone heard a higher purity level and increased detail in the sound. Even before the swapping, the system was already delivering very satisfying sonics (musical, great dynamics, strong hall reverb), but the JS-2 helped take it to another level. One auditioned track that highlighted the sonic improvement with JS-2 was a Decca recording of Rimsky-Korsakov's Capriccio Espagnol, by Ataulfo Argenta & LSO (pretty old recording) re-mastered by FIM.

 

The JS-2 is a winner! Kudos to John and Alex for a great product! Count me as another highly satisfied customer.

Hey look, it's a congregation of JS-2s! I think they are all conspiring to be shipped around the world this coming Tuesday. ;)

 

Ha ! You're in fine form today, must be a happy camper :)

No just delirium from lack of sleep (up half the night invoicing the last buyers and promising the next 10 people who inquired that I will catch up with them soon). Plus I am procrastinating going out to the hot garage to start making the 20 Oyaide/Belden DC cables to go with all those pretty JS-2s.

;)

 

But indeed, I am in a pretty good mood, thanks Dave.

Just got back and decided to try direct power supply to the Mac Mini SSD via the JS-2.

Not sure if I find any worthwhile gain to be honest. A tad (Minimal) less noise perhaps.

So the JS-2 and the MKK seems to be doing a swell job!

Your post is confusing, you're not sure if any worthwhile gain was made, but the JS2 is doing swell

Can you elaborate on that a bit

Perhaps it is my jet lag!

My base Mac mini was being powered by the JS-2, then decided to do the next thing on my list. Powering the SSD directly. As there was no discernible difference to me, I assumed that the power supplied by the JS-2 to the unit via the main supply was top notch and there was nothing more to be had.

YMMV. Or your ears may be more sensitive than mine?

 

The JS-2 other wise punches above its weight I have two other LPS to compare with.

JS2 running the last two days with two Amber Regen's at 9V in the main system. Just wonderful! Couldn't be happier with the way the system sounds.

 

Are you running the two REGENs from the same JS-2 outlet? If so, did you get a Y-connector? Thanks.

Installation completed in a bit less than one hour (I took a methodical and slow approach).

The instruction manual, the iFixit page, and Artifex's photos were very helpful.

Mac Mini with fan control along with the REGEN at 7V.

 

Just starting to listen...

Two quick questions for Alex and/or John.

 

1) I plan to leave JS-2, Mac Mini, and REGEN on continuously, as well as my DAC, etc. I assume this is not an issue in terms of heat (we shall see) or other things.

 

2) The JS-2 is plugged into the Monster 5100 MkII power box. Do you think that it would be better to plug directly into wall outlet since any power conditioning seems superfluous with the LPS?

Connected the JS-2 to my Adnaco S1-B optical PCIe board and my SOtM USB card.

From the first seconds, I got the difference. I had been using the HDPlex lps up until then.

One word . . . smooth. It's just a smoother (and more enjoyable) sound than what I had before.

Impressed with the service and pleased with the product.

Thanks for that Joel.

Had been considering getting a hdplex or js-2 (hdplex was more wallet friendly) but as you've reported a noticeable difference it has made the decision much easier in favour of js-2 :-)
