Hi All: Thanks Chris for sharing your methods. However, I have two questions regarding your methods. 1. Where can we get a free HDCD encoded wav file? 2 This is about Weiss Engineering DAC202's built-in bit transparency checker or in fact all such schemes. Let's say we have a 44.1/16 file. Now, using wav editor I change the sampling frequency to 96kHz and then again downsample to 44.1kHz. Because of sampling error the resultant file is far from original. Now I play this file and outputs to Weiss Engineering DAC202, even if the output path is bit perfect how it can possibly know that I have already manipulated the file? It can’t, because it has no clue about the original file, it has no reference. However, if you do the same the with DST/DD encoded wav file, it will not be recognized as 5.1 DST/DD and only static will be heard. Open or hidden DSPs can do such file manipulation. Also, I am not pushing my approach but just trying to find the best one. Now Chris and I have mentioned some methods, where are others? Hi All! Please share how do you test for bit perfection. Regards

Hi: I have been reading this forum for a while without any contribution and feel many questions always go answered. 1. How does one check and ensure bit perfection when sending data out of PC via USB, Firewire, or S/PDIF from soundcard? 2. What is acceptable remote for J River Media Center? Here is my contribution to these two questions. 1. Two years ago I learnt while reading a post on a forum that if a DST encoded 44.1/16 wav file or Dolby Digital encoded 44.1/16 wav file is played on a computer and if the output is recognized and played as 5.1 DTS/5.1Dolby Digital by a decoder, say a home theater receiver, via S/PDIF then the output is bit perfect. I have been using this approach by downloading such files from www.kellyindustries.com/sounds.html say, www.kellyindustries.com/downloads/dts_the_other_side_44khz_wav.zip and this approach works. I use such file and connect the S/PDIF out to an old Yamaha receiver and if the stream is bit perfect, it shows either 5.1 DTS or 5.1 Dolby Digital logo and plays the song. If I change the bit depth or sample rate using a wav editor (Sony Sound Forge) all I get is static and no logo. If I try to play this file via computer’s speaker all I get static via Winamp and Windows Media Player, however, VLC player does recognize and plays it fine. Even VLC player gives static if any manipulation is done to the file. This is a sure method, however, one need an external DTS/Dolby Digital to check the S/PDIF output. This is the approach I used with J River Media Jukebox 12 on XP. The HiFace kernel driver appears under Direct Sound but my Yamaha receiver shows the DTS/DD logo and plays the song. What methods do you use to ensure bit perfection? Chris! What is your method? All of you, please share. 2. I posted the second question a while ago here but there were no satisfactory answers. All those Iphone/Itouch fans, come on; accept it that the screen is too small for a satisfactory remote for a media server. Ipad does look promising but how to control J River Media Center via Ipad without using remote desktop application? Regards

Thanks to all for your responses. However, as I wrote that using laptop as remote is not an acceptable solution at least in my case. Some UMPC could qualify with remote desktop but no direct control of server. I waited for some time to post these comments but I believe either we really don’t have a fine solution or people who have the solution are enjoying their music heaven instead of spending their time on internet.

Hello: I have been reading posts at stereophile, audiogon and now at this site. Somehow, everybody is talking about everything related to computer based music server but nobody pays much attention to remote/control/touch screen…etc to control that computer based music server. I am sorry in advance if I have overlooked such posts/solutions or may be it’s only me alone who is faced with such problem. I bought and returned Sonos because of its sound quality and inability to do anything except 44.1k, nevertheless, 3.5” non-touch screen on the russian tank remote was inadequate. I think Squeezebox duet small screen is really a joke. Yes! itouch/iphone as remote with touch screen is great but there is no horizontal mode thus the effective screen is again small. Some of my songs with long names were difficult to find. Also you have to use itune with them. I am really frustrated that I am unable to find a good size screen remote for computer based music server. Many times I was tempted to build a silent computer based music server but then I stopped because I have not still forgotten the frustration of using a laptop as music server with no adequate remote. I used to do the remote desktop with another laptop, but what the heck. It always gets disconnected after a period of non activity and then who wants to enjoy the music with a PC on lap. Please all! Help me find a smart solution to remotely control computer based music server. Ideally, I am looking for a solution that has big (bigger than 3.5”) touch screen and no fan. HELP!
