[SlimDevices: Audiophiles] way to add AirPlay
Guys, Most of you may already know but for the few you can buy AirPort express and connect it the following way AirPort -Digital- Transporter (Digital in) AirPort -Ethernet- Transporter Advantages: 1) AirPort is 802.11n which will improve your data transfer rate and if Transporter is the only 802.11b/g device on your wireless router then you can go all 'n' 2) You can connect AirPort Digital out to either your pre/processor or to Transporter digital input that will allow you to switch input using iPeng and use AirPlay -- MediaCenter Source Device: Transporter Room Correction + DAC + Preamp + Amplifiers: HK 990 Speakers: Magnepan 1.7 MediaCenter's Profile: http://forums.slimdevices.com/member.php?userid=32623 View this thread: http://forums.slimdevices.com/showthread.php?t=89691 ___ audiophiles mailing list audiophiles@lists.slimdevices.com http://lists.slimdevices.com/mailman/listinfo/audiophiles
Re: [SlimDevices: Audiophiles] New Squeezebox Touch Mod
Hi I made the changes in command/temp fashion last night, up to jive_alsa 55 and spdif 51. Fascinating. Without changing the jive from default, 59 was shocking in the change possible but I preferred 44 - 48 looked to have more potential. Can I clarify a passing comment earlier in the thread? If I now put the powered HD directly in the Touch, addresses will change with the change of hardware and values will not be applied correctly, or not all all? It certainly sounds different, although the values need to be different. I don't know if they are the values as set or not. I really want to use the Touch this way, HD direct. -- electric beach electric beach's Profile: http://forums.slimdevices.com/member.php?userid=49103 View this thread: http://forums.slimdevices.com/showthread.php?t=89359 ___ audiophiles mailing list audiophiles@lists.slimdevices.com http://lists.slimdevices.com/mailman/listinfo/audiophiles
Re: [SlimDevices: Audiophiles] New Squeezebox Touch Mod
Last night late, I pushed the reset button on my modified Touch in my bedroom system (http://cgi.audioasylum.com/systems/5771.html) and set it back to factory settings to get the latest firmware (7.6.0 r9548.) I then added Klaus' TT 2.0 w/ the buffer @ 3600 and only the analog outs turned on. WLAN shut off and screen off as well. Noting the improvement in sound quality as each mod was added. I then added the entries from this thread, skipping the spdif line as it is already off. There was another improvement in clarity and detail retrieval, a clearly discerned improvement in playback that I had been unable to hear previously.

Re: [SlimDevices: Audiophiles] New Squeezebox Touch Mod
As I increase the SPDIF priority, there is a slight decrease in bass for each incremental value. Did anyone else note it?
