Hi guys,   I've been a little bit out of the game for a bit but I really need some help looking for a DAC.    Here's the system its going into:   SB Touch or SB Emulator (Squeezelite on a MacBook Pro) Digital Output --> (The DAC I need) --> EHHA Rev A or Bijou Amp (have both) --> HD800 and...

I think this really depends on the resolution of your system. I can hear a big difference between my Opus DAC, ODAC, and the built in DAC on my Total BitHead. This is using both an EHHA Rev A Amp or a Bijou Amp with HD800's and good source material.   If you're system doesn't need a high...

So here's a puzzler... I'm getting a strange harsh hiss noise in my system that's happening before the amplifier (it can be amplified). My system I'm hearing the noise with: Netgear ReadyNAS Ultra 2 running Logitech Media Server --> LAN Ethernet --> Logitech Squeezebox Touch running Enhanced...

So another update on the ODAC issue. This past Tuesday I had shipped the ODAC to JDS Labs for inspection. On Friday I received the ODAC back with a note that there was an issue with the USB section of the ODAC, and it was replaced for free!   Thanks JDS Labs, A+ company!   Definitely will...

JDS Labs was very quick to respond to my email that I sent them about the ODAC. Here was their reply:   Sorry to hear that. I suspect you have a bad USB connect. Please ship to the address below and we'll inspect:   JDS Labs, Inc. RMA #XXX 907 N Bluff Rd, Ste 2A Collinsville, IL 62234  ...

Sounds like the next step is for me to get in contact with JDSLabs and see what they can do. I'll keep this thread updated so if others experience the same issue, they will know what to expect.

I should probably mention that the noise on startup isn't hears through headphones, but just normally when I'm near the ODAC and plugging it in to USB. But I think you're right, I will probably have to get a new one. I'm not sure I have any more warranty on this one anymore though.

Yeah.. I've tried different cables. Like I said, I use the same cable with a TotalBithead and its fine. Its definitely not a cable issue. Its the ODAC.

  I know what you mean but the driver for the ODAC should be built into the chip. Its not supposed to require any extra drivers on Windows, Linux, or Mac. It's supposed to be plug and play.     I'm using a 8" or 12" USB cable from Monoprice with a ferrite bead on the mini-USB end and...

Final Update:   So another update on the ODAC issue. This past Tuesday I had shipped the ODAC to JDS Labs for inspection. On Friday I received the ODAC back with a note that there was an issue with the USB section of the ODAC, and it was replaced for free!   Thanks JDS Labs, A+ company!  ...

Hey guys,   I'm having some trouble with my ODAC. When I plug it in to certain computers or sources, it will work, and with others it refuses to output sound. See examples below:   Windows 7 Desktop (works with other DAC's over same USB port) --> USB Cable --> ODAC = "Windows doesn't...

I'm interested in hearing people's opinions on DAC's (especially DIY) that can outperform the ODAC. I don't have enough money for the Buffalo III and I wonder if the Buffalo 3 only adds more options but not really better sound than the ODAC? Everything else in my system is top notch, at least...

I used that first case to house my current ODAC. I also used that case about two years ago to house a PIMETA. :) Those little amps were fun to build.

The Monitor 03 looks like it outputs into analog which would make tapping into the I2S output very difficult in the middle of the board. I'm sure an more electrically-inclined person could do it. I'm not inept by any means but my degree (next month) is in Mechanical Engineering, so I only know...

Quote: Same.

Quote:   Hey thanks for this. I like that AckoDAC stuff. It is pricey! Definitely something to consider. Its kind of hard to pass it up because its more or less exactly what I'm looking for. I wonder if the new TPA USB 32bit board will be significantly cheaper, or who knows if it will...

Honestly if you want a cheap standoff that is customizable to ANY height:   Pick your favorite length 4-40 machine screw. Then drill a hole through the bottom of your chassis that is "close-fit" for a 4-40 (#32 drill bit). Put the 4-40 screw up through the hole into the chassis and secure it...

I'm very interested in this and will be following it. I always love me a good tube headphone amp. I've never designed an amp before, so reading all this is very educational!

I'm surprised there isn't a competitive "go-to" USB/I2S Class 1 board out there on the market for DIY'ers and we have to stoop to the technical know-how of eBay sellers who don't post detailed specs.

That's just a chip. I was looking for a board that can take USB input and convert it to I2S output. Its a good chip and I'd use it if I could find a board that has it.   Any ideas other than the new TPA board that's coming out?   EDIT: There have been reports of the Tenor 7022L chip...

Hi guys,   I'm setting out to build a Buffalo III. I'd like to have both USB and S/PDIF (Toslink) input. I'm not a huge fan of the Twisted Pear Audio USB receiver board. I used one in my Opus DAC and its really not that great. Its limited to 16/48 and the chip is a dated now.   Does...

I would highly, highly recommend a Cavali Audio Bijou or Cavali Audio EHHA Rev A (MOSFET version).

Quote:   I've been meaning to try this. My HD800's aren't harsh, but I'd like to see how I like the mod.

Quote:   What BMF is trying to do is basically achieve a flat response from headphones (T50RP's) for his own ears. His work does not try and mimic speakers in a room. Both free field and diffuse field equalization try and mimic what a speaker would sound like in an anechoic room (well...

I recently listened to these for the first time at ChiUniFi '12. My favorite sound with them was using the Ray Samuels DarkStar amp. It was a fantastic pair.   After hearing them I had to have a pair so I bought one that should arrive soon!
