Try pressing on upsampling while your music is playing and turning it off, muting it, etc. Perhaps it would go away after burn in.

If not, just return it for a new one.

The power cord as it didnt come with a North American one, but it hasnt happened since I started using the default usb cable

Seems like they made you a bad usb cable.

If that still didn't work, plug your USB cord to a different socket on the computer. (Try and not do it on a USB 3.0 Port).

Hey Tim,

i got it updated and passed

but when i click the little icon on the tray, it still gave me blank on F/W

the unit work perfectly should i return it? or just deal with it?

Try uninstall the driver, restarting your pc, re-updating the F/W, and re-installing the driver.

All three boxes should have numbers inside.

Turns out there was an FR right next to 105°.

Switching it to Panasonic FC is probably a downgrade. That is, unless you need some added resistance, i can't see why you'll need it though as FR/FM replaces FC.

 1500uf 25v  FR ripple=2600, FM=3190

 2200uf 16v  FR ripple=2600, FM=3190

   470uf 16v FR ripple=950, FM=1290

   330uf 25v FR ripple=950, FM=1240

All the FM's are the exact same diameter and lead spacing as the FR's but with greater ripple.

I've already stated that FR/FM is better than the FC.

FC has more resistance, and doesn't do good in this application with less ripple current than the two.

FR has a lower and higher uF range than the FM.

FR has slightly (barely) more ESR than the FM, and that's only for certain nominal caps.

FR has twice as much "endurance" life span than the FM.

Doesn't matter if the FM can resist a higher ripple current, the FR for this mini regulated psu pcb is good enough and even with lower ripple current specifications, was made to last twice as long as the FM.

FR  > FM > FC

reinstall driver did the trick

thanks tim

Glad you got it working

Would I be able use my essence STX to send a virtual 7.1 signal to my essence ONE?

Also, electronic echo sounding thing has not happened since I stopped using the audioquest cable.

Where did the capacitors go?

Oh, there it is, partially..

Did you finished changing the capacitors? If yes what kind of a difference has it made?

I am going to test some more op-s in the one, here is a part of the op-s that is going to be tested:

so i'm using the MUSES edition on XLR as a DAC only, compare with my Ayre QB-9, i would say that ASUS is a little bit better sound on my stax009.
 

thumb up to asus for the product as such a low price.

I only resumed tonight as my soldering tip started to fail me and needed a new one.

That is a lot of op-amps (especially the metal cans)

 

As of now, this is what i have going on for the project.

 

• Generous amount of thermal paste on PSU Heatsinks (using credit card method) 
• Aluminum Heatsink on Smaller Fin side of PSU's Heat-sink (Size 25mmx25mmx10mm)
• Nichicon Audio KA 50V Capacitors
• 2x Elna Silmic II Capacitors for RCA Out (220uF @ 35V)
• Gold Plated DIP-8 sockets. (to raise the TO-99 > DIP-8 adapter so it wouldn't hit capacitors/headphone out & volume meter)
• Replacement LME49710HA w/ aluminum heat-sinks
• A few OPA op-amps for testing

• Custom rhodium plated power cord for Essence One
• Silver Plated OFC Wire w/ silver plated Dupont Female Connector for PCI-E cable (Connecting PSU PCB to Audio PCB)
• Remove solder from every joint, Replace with Kester 5% Silver Solder (SN95AG5)
• Aluminum Heat-Sink on Analog Devices ADSP-21261 (Size: 14mmx14mmx6mm)
• Aluminum Heat-Sink on CM6631 (Size: 11mmx11mmx5mm)

 

WIMA CAPACITORS:

From what i can tell, is that the 2200/100 and 1800/100 is FKP 2. (black marking)

0.022/100 and 8200/100 being FKS 2. (white/silver marking)

 

I used a flash light, which turns out, the bottom of the film capacitors were yellow epoxy (http://www.wimausa.com/EN/marking.htm)

 

FKP 2 is already good for audio application so no need to replace it.

From what i can see, switching the FKS 2 for FKP 2 will improve, or finding the same capacitors in lower tolerance.

 

TAW is going to be sending me a few sample FKP2 WIMA Capacitors for me to replace the stock ones.

This is what im aiming for, hopefully it will work out.

 

(4) 0.022uF/100V/2.5% FKP2 (Stock Essence One : 10% Tolerance FKS)

(6) 1800pF/100V/2.5% FKP2 (Stock Essence One : 5% Tolerance)

(8) 2200pF/100V/2.5% FKP2 (Stock Essence One : 5% Tolerance)

 

(8) 8200pF/100V/5%, or 2.5% FKS2 (Stock Essence One is 10% Tolerance)

OR 

8200pF/630V/10%, 5%, or 2.5% FKP (Stock Essence One is 10% Tolerance FKS)

 

From what i've learned, the lower tolerance, the more accurate levels the film capacitor produces which is more ideal.

Also, that it's okay to use higher voltage capacitors. They offered me 630V for the 8200pF (might be oversized), but i decided to try it out and see if it would fit. Being FKP instead of FKS should yield some improvements.

 

Correct me if im wrong.

That's great!

I'm happy that it improved your sound quality.

The stax-009 is sexy. too bad i will never afford one.

I decided to get the muses addition, but can't find a place that ships outside US!..appreciate the help guys...

Really, aren't they only on sale at EXcaliberPC ? their shipping calc lists pretty much all countries.

I'm still waiting for a UK release date
