Review: ZERO 24 BIT/192KHz DAC/Headphone Amp/Pre-Amp - Page 150

The ol' LT sample pack - 1361, 1364, 1469. Unfortunately I'm pretty sure the probably lies elsewhere than the particular opamps I'm using though, as it's irrelevant which pair I have in the headamp. No matter which I use the problem remains the same.

lol its mainly due to your reviews :P but seriously cheers dude, always wanted to get some serious headfi gear and xtremely pleased I took the plunge.

qq - does anyone else's Zero have a tiny tiny hum when its on, not coming from the headphones but unit itself. Not any kind of major problem since you have to put your ear pretty near it to hear.

I got mine to day, but how can I make it work? I have tryed to connect it to my PC with coaxial and toslink and all I can hear is some flickering noise when I connect my headphones to the Zero. I have set my soundcard to use digital out.

LaZyKun: Mine does also have that hum.

ZERO USB Mod prototype

Zero with USB Mod prototype:

I bought a nice USB analogue sound card cable with Burr Brown PCM2704 (used in Meier Audio Corda Opera). Stripped the analogue part to use the S/PDIF output.
Had to removed the coaxial socket of the ZERO, because I didn't have the heart to put a hole into the chassis. Now the coaxial switch is the USB switch.
Glued the USB board onto some resistors. Fits like a glove.

Positive: No toslink jitter, USB conversion into Zero's receiver chip, no need for a sound card, plug-and-play
Negative: only 32kHz, 44.1Khz and 48Khz sampling frequency

Next: PCB with USB socket, no glueing. ZERO has to switch between optical, coaxial and USB.

Just a thought. The headphone amp is dependant upon which Opamp you have in the DAC, so maybe trying a different Opamp in the DAC will change the results you are having in the headphone amp, with trying different Opamps? Check it out and see.

Thanks for the suggestion.
Just a question: if I use the Turtle Beach strictly as a converter from USB to digital, will it effect (e.g.: colour) the sound in any way?

Furthermore: I wanted to buy it from Amazon but on the product page it says: 'Dance a GoGo : Sexy Nightclub Workout'

Amazon.com: Dance a GoGo : Sexy Nightclub Workout: Andrea Lin,Darko Mitrevski: Movies & TV

Thanks,

Ben

I've read some reviews about the Turtle but most of the people are using it as a external sound card. I can't find any information when used strictly as a converter/transport from USB to digital.

Are there any other (cheap) solutions?

Maybe something like this, with no 3D, with optical would be better?

When I tried to order and checked out it came up with:

Minimum Requirements:
Sorry, this order does not meet the required minimum dollar amount for an international order.
Please added $20.01 to your order.
This is turning out to be a real soap

Sorry! I had no idea they impose a minimum like that! Check the maker's site and see if they can do it.

"High-resolution 48 kHz converters for premium audio quality" isn't very good right?

Looking around, it seems to be the "standard" for this kind of application and price point. I'm having trouble locating some with higher rates. Have you seen any??
