For anyone that owns a "green" and has updated to the "amber" you might be interested in this.

In this? I better go there now!

I purchased a iFi USB power supply. It did not mate well with this regen unit - sibilance and smearing. Alone I thought the iFi created a better sound. Right now I have my regen parked to the side.

Regen arrived yesterday. Connected using the solid adapter. Generic USB cable from laptop.
Wow! Gobsmacked. Exceeds expectations by a mile. My stereo is on steroids!

Obviously from the comments a VG product. my question as a non computer person is how can this discovery and implementation be incorporated in the computer or DAC ? Are the standard USB and other connections flawed ? Please explain.

Did anyone try both the iFi USB power AND the Regen in series?

HAL · « **Reply #107 on:** 23 Jun 2015, 08:26 pm »

I have both here. I will give it a try and see what happens.

I think the way to do this is the PC -> USB Regen -> iFi -> DAC. This way the lowest noise power supply is feeding the DAC. Still needs two USB cables as I would do the solid link between the Regen and iFi.

Regen MUST always be closest to Dac to work best…otherwise the entire effort has likely been wasted.

Inside the dac is NOT a great idea, unless you have separate power transformer and separate power plug and separate grounding scheme.

I had the same experience as BRM with the USB Regen and iFi separately. I like the iFi more.

Will see what happens.

Yep, and when the little PS add on is released that could take it over the top for those that require 5Vdc on the BUS.

I just tried it again with my father-in-law in the room and he clearly heard the sibilance with it in place. Took it out and all is well. When I get a chance I'll try it without the iFi unit again.

So Big Red, is it my understanding you are using BOTH the Regen and the iFi together at the same time? If so that is not recommended.

I am in no way suggesting that you are not hearing what you are but you (and Hal) are less than 1% so far. May I suggest that you check with Alex (or John) at Uptone Audio and see if there may be a cause and a solution. Of course it just may be a synergy problem.

I know a few Regen users systems had a problem using the included power supply (seems the systems picked up the SMPS noise) but when they tried a good quality linear power supply they had excellent results with the Regen.

Good luck.

I got nothing out of the Regen with my setup (LPS and SMPS used), so I moved on.

Hello big RED!

it's great to know some other regen user is getting what I am hearing, sibiliance.

It is so obvious and its quite harsh to the ears, so much so that you simply cannot convince yourself that the sound is improved.

Is there something wrong with our systems? or something wrong with our regens?

I was so super excited that REGEN arrived finally but once I plugged in I find the sound harsh and edgy and lots of sibiliance.
I let it burned for two to three days and it was the same.

I tried both the SMPS and my own LPS as well.

Shawn, HAL, BRM and Kukiman, could you please lay out what your playback chain is like?

Just curious to see if there is an obvious explanation.

I dont hear this sibilance at all, but again, I use the Green with Corning.

HAL · « **Reply #117 on:** 25 Jun 2015, 11:13 am »

My chain is:

HAL MS-3 Music Server -> Virtue Audio USB cable -> USB Regen -> dspMusik as USB async DAC -> Audio Alchemy HPA 1.0 -> HiFiMan HE500's.

Mine is not a sibilance issue. Mine sounds rolled off in the top end and dulling of transients as compared to the same setup without the USB Regen.

Big Red Machine · « **Reply #118 on:** 25 Jun 2015, 12:36 pm »

HAL MS-2 Music Server - TotalDac USB cable - insert a gizmo of your choice here - Chord Qute EX dac - Dude - etc.

Tyson · « **Reply #119 on:** 25 Jun 2015, 02:35 pm »

No sibilance with mine either. I'm more in line with HAL, the top end is less pronounced in my setup. But in my case, that's a good thing - I don't lose any detail, it's just more pleasant to listen to. And the bass is substantially cleaner and clearer.

My chain - dedicated PC music server with SOtM USB card -> Regen Green -> generic USB cable -> Regen Amber -> iFi iDSD Micro DAC -> 6sn7 Tube preamp -> First Watt Aleph J amp -> Serenity Acoustic Super 7 speakers.
