I would start from this one   Price is reasonable, NEC chipset, USB2 I've read many have encountered troubles trying to use a USB3 chipset with the HiFace

Hi leeperry, did you try this at the end?

A bit off topics but, is there any soundcard with a s/pdif IN accepting Dolby Digital 5.1 on it?

punk_guy182 these kind of problems are really annoying, I hope they will be solved with next driver release! In the meantime, have you received the Oyaide DB-510 digital cable? Any thought about it?

Looks nice, despite I don't like proprietary drivers. Are Linux drivers in the plans?

Corsair hx520 Gigabyte GA-EG45M-DS2H Intel c2d E4400 Teamgroup 2Gb ram DDR2 Asus Xonar Essence STX result: 108 dB = 220ps

I think it would be interesting to compare the outgoing jitter of our digital sources, in order to understand which device does better in this field and if clock mods can bring measurable benefits. This is the procedure:Set 44.1/16 as default audio format in the option of both the playback...

At least now you are sure that something is wrong on the hardware side and it's not just a software misconfiguration... Hope the Essence will be back soon and fully working!

You can follow that guide for sure! The only thing you need is a loopback cable to connect the RCA out to 6,3 mm jack line-in

Playing around with the RMAA, I've noticed another "strange" thing: in the Frequency Response multitone test the left channel is about .2dB higher than the right one! Modifying the balance from 100-100 to 98-100 (L/R) in the windows audio panel does improve the things, lowering the gap to .05dB...

@192 khz you get 1 sample every 5208333 ps. A jitter of 750 ps means the error of the clock is below 0,02%, while a jitter of 5 ps takes it down to 0,0001%. I didn't think there could be any audible difference between these two values.

Rob, do you think the CS2000 chip would still make any hearable difference on a clock with a rated jitter of <= 5ps like these?

Playing around with RMAA I've noticed that with the Burson as output buffer the Stereo Crosstalk falls down to 53dB, against a value of 115dB with the lm4562! All the other parameters (noise, frequency response) are quite similar. Is it normal?

Does the CS2000 chip to reduce jitter on the ST affect also the S/PDIF output, or just the RCA analog outputs?

Can this DAC be used as preamplifier, with a direct connection to a power amp or it lacks the volume control?

Does somebody have tried the Essence with Windows7RC1? I do and it seems to me it's an improvement over Vista: the sound gets more transparent with tighter bass. The side effect is that the Asus Audio Center does not work anymore, and the Windows Audio Mixer does not open. To change the...

Hi guys, sorry for having been away from this thread for a little while, but now I'm back In the meanwhile two important things have simple revolutioned the playback of my audio system:the LM49720NAs have arrived I've applied the digital correction using DRC First of all, let me speak about...
