Sony HAP-1ZS. Nothing like it for the price.I don't sell it BTW.Steve N.Empirical Audio 
Frequency range s of digital noise s
Ptss - Designers usually don't target specific frequencies and the good ones avoid using too many filters. Filters usually impact SQ. Sometimes designers must add ferrite beads or similar to pass FCC class B emissions.Good design practices are the... 
Frequency range s of digital noise s
Emitted is the key word here. Emissions are the same as radiated emissions. Most products are limited by Class B to less than 40bDuV/m, at least those that pass Class B testing. This is low enough so you will not have interference between componen...

The best grounding sceme is to isolate every components grounds from each other in the signal cabling, but use common earth ground for all, so there are no ground loops. I do this using combination of good analog transformers and digital isolators. 
When is digital going to get the soul of music?
I listened through headphones to master tapes on a pro machine at RMAF 2013. Not impressed frankly. I like my digital better.Steve N.Empirical Audio

Matt - make sure that all 4 AC runs are from the same phase in the panel. For your digital, you may want to use one circuit for all of it.Isolated grounds do work, but as Al says they do not meet code. I have a friend that did this. He put a 6 foo...

Matt - another thing I did in my listening room was stagger the footings and support pony walls under the floor, so the floor was not supported in the middle, causing a second harmonic in the floor.Also, I used two layers of 3/4" MDF on the floor,...

Thanks Al. I was looking in the 2014 buyers guide. I guess I don't get that with my subscription...Steve N.Empirical Audio

There are only reviews of mini-DACs in there and the best-rated DACs page does not include the W4S. Are you talking the November issue of TAS?

Matt - Here are a couple of simple and inexpensive things for your power:Have the electrician install plastic flexible conduit terminating to plastic boxes. Get black, white and green THHN 12 gauge wire and have them precut and twist the black and...

Melb - some things that are still variables, even with DLNA is the CODECs for compressed music on the computer. They can screw up the SQ. Also, the S/W that formats the data to send to be packetized. That can be screwed-up.Steve N.Empirical Audio

Looked at the PS Audio Bridge. Looks like their own design. Its gotten some good reviews....

"if the sound of the PS Audio Bridge is representative of what Ethernet has to offer"Just speculating, but it might be a case of using an OEM module rather than designing it themselves. I have not seen what they use. This happens a lot in this ind...

knghifi - Isn't the storage of the data in a buffer after de-packetization in the device sufficient?What purpose does it serve to store the data in another memory buffer?I do reclock the data to reduce jitter.Steve N.Empirical Audio
