Re: [SlimDevices: Audiophiles] Transcode and upsample at once?
I doubt that this is doable within the transcoding framework. It just wasn't designed with that sort of flexibility in mind. One thing I do know is that you don't want the output type in SoX to be WAV if PCM is the target. You need to use the output type 'raw' in SoX, as the Squeezebox will be expecting a headerless stream. With type WAV you're probably hearing a click at the beginning of each track, which is the WAV header being played.

Re: [SlimDevices: Audiophiles] How old are these audiophile reviewers???
A modern audiophile has little in common with a DIY hobbyist. One of the biggest differences is that the DIY hobbyist needs to know something about how things work, while the modern audiophile only needs a computer keyboard and a dictionary of superlatives.

Re: [SlimDevices: Audiophiles] How old are these audiophile reviewers???
Oh yes DIY tube amp building is definitely a subsect of a subsect, but of our 30 strong group, there are younger members the youngest being 18. Plus there is my son, who is 28, has built several of his own tube amps and has a small business making and selling hand-crafted wooden chassis. There are others who also have small businesses making and selling self designed and built loudspeakers. I totally agree that the hi-fi business is doomed if it carries on as it is doing and peddling voodoo to the gullible. I know that in the UK there is something of a return to the roots of hi-fi as it was in the fifties, with enthusiasts building their own gear. The days of mass market hi-fi have gone forever and the industry will have only itself to blame when the end comes. It is salutory to note that all of our DIY group once used nothing but commercial gear, but have rejected it completely as it was nothing more than a money pit, that produced mediocre sound quality. Here is a sample set of pictures of the stuff we do First my system comprising home designed and built valve amplifier feeding my own design Metronome tapered quarter wave loudspeakers.

[image: http://i49.photobucket.com/albums/f296/Dingsking/IMG_2756a.jpg] Yes I suppose we are part of an underground movement but in our neck of the woods it is getting bigger.

Great insight! I never thought of the Magic/Monster Cable phenomena from the sales/margin prospective. That goes a long in helping to explain why the mass market audio retails so willingly push overpriced cables onto the unsuspecting public. Mass market Blu-ray player: $79 with a razor thin profit margin. Magic HDMI cable: $79 with a super wide profit margin.

Re: [SlimDevices: Audiophiles] Triode's USB 24/192 plug in - sound quality impressions
JohnSwenson wrote: I have a HRT Music StreamerII (not the +), it works very well with Triodes plugin and a hub. Adding TT3.0 significantly improves the sound, with this combination it's getting astonishingly good. (it's not the best, my homebuilt DAC still blows it away). The II with TT3.0 is sounding better than several other way more expensive S/PDIF input DACs I have. (except for my own design -- I'm not biased am I?) I had to do a little work to get TT3.0 to work with it, I had to set the buffer to over 5000, and I had to change some of the priority settings. The esiest way to change the priorities was to just turn them off all together. I didn't have time to figure out which one caused a problem. I tested the screen off part of TT3.0 and it didn't make any difference so I left the screen on. The part of TT3.0 that seemed to make the difference was the kernal settings, when I implemented just them I got the same sound improvement. John S. John, I have placed my order for HRT Music Streamer II+, hence very interested to learn the changes to your system with HRT. I have: - Installed EDO - Installed TT3.0 over it - Changed priorities in TT file to Logitech default - Made the changes suggested by SBGK on the various .lua files - My buffer setting in the .lua files are 4200 - Disconnected screen - Removed Toslink on SBT You are also suggesting kernel settings change. Can you share what the kernel changes are?. Also what buffer size is best. lake_eleven's Profile: http://forums.slimdevices.com/member.php?userid=48979 View this thread: http://forums.slimdevices.com/showthread.php?t=94855 ___ audiophiles mailing list audiophiles@lists.slimdevices.com http://lists.slimdevices.com/mailman/listinfo/audiophiles

NoRoDa has provided a lot of the details of test conditions in various posts in this thread and the thread to which he linked when starting this thread. Btw, it is easy to find those posts by clicking on the link that shows NoRoDa's username, and then choosing View Forum Posts. Also don't forget to see the ancillary material by member baardbaard, who was also involved in the tests. Perhaps most important, NoRoDa has already said that the test ...wasn't double blind or very scientific in any way..., which may be why more details were neither offered or requested by other forum members. But now that you're a part of the discussion, feel free to ask about details that haven't been included yet. My take-away from NoRoDa's disclaimer is that that time would be better spent trying to improve the protocol rather than trying to reproduce it. Having two SB Touch players to test side-by-side seems to be a critical improvement over (almost?) every other comparison that has been posted on this topic in this forum, which generally compare the same Touch before/after mods. aubuti's Profile: http://forums.slimdevices.com/member.php?userid=2074 View this thread: http://forums.slimdevices.com/showthread.php?t=94418 ___ audiophiles mailing list audiophiles@lists.slimdevices.com http://lists.slimdevices.com/mailman/listinfo/audiophiles
[SlimDevices: Audiophiles] Display Off screensaver
I will post this here as its clearly unproven and something to discuss on the audiophile board I've just posted a new app to the repro for Squeezebox Touch - this provides an alternative to the built in Screen Off screensaver which disables some of the processing associated with the screen when the screen is off. It does the same as TT screen off + also disables some internals to the squeezeplay application related to rendering the screen when it is off (reducing cpu load for scrolling text etc when the screen is off). The intention is you may want to try it as a when playing screensaver which will bank the screen after the delay and hence use less cpu power. Whether this has an impact on the audio quality is unproven and the reason I am posting here... To install: On the player goto 3rd Party Apps, unselect recommended Apps only and then select Display Off [As an aside - I note that with the EDO app installed and the internal digital out selected so that the analog output is not enabled, if you measure the analog outputs on an oscillocope then you see a much lower noise floor than when the analog dac is enabled. At the limit of my simple scope's gain I can see noise which is related to cpu activity - I believe looking at this, that disabling the screen does have a measurable impact, but it is very much at the limit of what I can see and well below the normal noise floor of the analog output.
