Re: [SlimDevices: Touch] Squeezebox Touch Question for Audiophiles

I'm keeping an open mind on this. I've studied a lot of info on the web about this, and there does seem to be a view that there may be something to investigate here.

Re: [SlimDevices: Touch] Touch Review in upcoming Stereophile issue
Audio is a diverse market with diverse individuals. Any review magazine faces that fact no matter what approach they take. Getting consensus is like hearding cats. It just isn't going to happen. I enjoy Stereophile even though I cannot afford many of the items and I probably don't agree with some of the opinions published. No harm... no foul as far as I'm concerned. I'm just glad they are open-minded enough to review a $300 part that is aimed at the mass market. -- Kevin Haskins Kevin Haskins's Profile: http://forums.slimdevices.com/member.php?userid=30729 View this thread: http://forums.slimdevices.com/showthread.php?t=81346 ___ Touch mailing list Touch@lists.slimdevices.com http://lists.slimdevices.com/mailman/listinfo/touch
Re: [SlimDevices: Touch] Best Volume Setting
Mnyb;570459 Wrote: 100% and then use the preamps level would be better. 50% is to little , sbs uses a 24bit digital volume control so it's quite good, but 50% would be to close for comfort. 100% if you have a volume controll in the preamp this would maximise snr ratio on the Touch. I'm not sure of the spec re output voltage bu the Touch at full tilt 100% should compare roughly with any CD player and you dont use volume on those. Historically squeezeboxes have had sensible output levels not extremely quit nor to much output. If you have an vintage preamp of some kind maybe a analog attentuator at input would be usefull, some older preamps could have very sensitive inputs It is fairly hot at 100%. I measure PP 5V on the scope with just some music playing.I should upload a sine wave and get a nice pretty picture.I'm trying to use it on my active speakers with 60-70% -- 100% so that I can just avoid dealing with another volume control. -- Kevin Haskins Kevin Haskins's Profile: http://forums.slimdevices.com/member.php?userid=30729 View this thread: http://forums.slimdevices.com/showthread.php?t=81343 ___ Touch mailing list Touch@lists.slimdevices.com http://lists.slimdevices.com/mailman/listinfo/touch

Re: [SlimDevices: Touch] How well does the Touch work?
mlsstl;533436 Wrote: I've used a SB3 with a Lavry DA10 DAC for the past couple of years as my primary music source. The Touch arrived Friday and I spent quite a bit of time the past couple of days listening to the Touch. I level-matched the SB3/Lavry output with the Touch and synced the two players. I was then able to switch between the two inputs for back-to-back comparison. The difference between the SB3 analog out and though the Lavry is quite noticeable to me (though I don't consider the SB3 analog bad - just rather pedestrian.) In comparing the Touch analog out to the SB3/Lavry, the difference is extremely subtle in my book. I have to strain to hear the difference. I am very impressed and will probably end up selling my Lavry. In audiophile-land, the Touch has no right to sound as good as it does for the price. ;-) However, I'm sure others will disagree with that thinking, but that's fine by me. When I have to strain to hear the difference between two pieces of equipment, that's a sign for me to let go of the issue and just enjoy the music. It is just good rational decision making. I see so many people who let other people determine their preferences that it is refreshing to see the other side of the coin. -- Kevin Haskins Kevin Haskins's Profile: http://forums.slimdevices.com/member.php?userid=30729 View this thread: http://forums.slimdevices.com/showthread.php?t=77145 ___ Touch mailing list Touch@lists.slimdevices.com http://lists.slimdevices.com/mailman/listinfo/touch
Re: [SlimDevices: Touch] Volume readout in dB?
Valentino;533136 Wrote: Is there a way to display the Touch volume setting in dB yet? If not: To whom do I donate? Have been using and loving this part of Herger's MusicInfoSCR plugin for Classic and Transporter, but as far as I understand this plugin is not compatible with the Touch. You could do it in dB of gain or amount of voltage gain but obviously it wouldn't translate to dB of output because you would also need to know the gain of the preamp/amplifier attached and the sensitivity of the loudspeaker. Then of course you would need to know the measurement distance so once you get to actual dB output the situation becomes complex and dependent upon several system variables. So...dB of gain is somewhat arbitrary as is the volume bar. -- Kevin Haskins Kevin Haskins's Profile: http://forums.slimdevices.com/member.php?userid=30729 View this thread: http://forums.slimdevices.com/showthread.php?t=77161 ___ Touch mailing list Touch@lists.slimdevices.com http://lists.slimdevices.com/mailman/listinfo/touch

Re: [SlimDevices: Touch] Why Purchase a Touch??
For me it is the form-factor and dedicated design. PCs are great all-purpose tools but they rarely have the elegance of a purpose designed application hardware/software platform. The Touch is compact, has a nice form factor and easy interface, can act as its own server (so I can plug-in an external drive), and from all accounts, respectable hardware for audio reproduction. Sure... I could build a fan-less computer, throw a copy of Windows on it and run a touchscreen LCD, either a high-end sound card or run to an external DAC but it isn't as polished as a dedicated product. -- Kevin Haskins Kevin Haskins's Profile: http://forums.slimdevices.com/member.php?userid=30729 View this thread: http://forums.slimdevices.com/showthread.php?t=76721 ___ Touch mailing list Touch@lists.slimdevices.com http://lists.slimdevices.com/mailman/listinfo/touch

Whether you can hear it or not is not the point. The fact that many people believe THEY can hear it and are willing to pay for it is why it has value.

Re: [SlimDevices: Touch] Powered speakers for Touch
I'm designing something for my personal use at home. I design transducers and loudspeakers for a living so it isn't too hard for me to put together something that fits my needs in terms of size and function. I'm milling an aluminum base that goes on top of one loudspeaker and holds the Sqeezebox Touch. It is an active design so the amps and DSP are on the back of the loudspeaker. There is one wire that connects the two and the signal stays in the digital domain until after the DSP where it goes through the D/A converter and into the Class D amplification stage. My wife didn't want anything but a remote and the speakers have passed her small enough test. Once I finish I'd be happy to post pictures and details. -- Kevin Haskins Kevin Haskins's Profile: http://forums.slimdevices.com/member.php?userid=30729 View this thread: http://forums.slimdevices.com/showthread.php?t=74658 ___ Touch mailing list Touch@lists.slimdevices.com http://lists.slimdevices.com/mailman/listinfo/touch

Certainly if there is some component that prevents the plant to hear these differences is pointless to change the DAC I will experiment with the internal DAC of the Touch but I think i will use the coax output to connect an external DAC like the Musical Fidelity VDAC that promises good performance at relatively low cost I design transducers so I can safely say, it doesn't matter how much you spend, or what the marketing department says, the very most expensive and best loudspeaker has orders of magnitude more distortion than does the DAC in the Touch. ;-) That is my only point. -- Kevin Haskins Kevin Haskins's Profile: http://forums.slimdevices.com/member.php?userid=30729 View this thread: http://forums.slimdevices.com/showthread.php?t=72246 ___ Touch mailing list Touch@lists.slimdevices.com http://lists.slimdevices.com/mailman/listinfo/touch
Re: [SlimDevices: Touch] technical info audiophile about SB Touch
perito industriale;493639 Wrote: But that got to do! You're comparing 2 different things. You can not compare the distortion of the signal and the power .. :-O Distortion then is not the only parameter on which you decide the quality of a component hifi / hiend! is important but not the only, if you're a designer you should know THD+N is pretty useless as a sole metric, that is true. Especially with loudspeakers where the on/off-axis FR measurements are more important. But... when you are splitting hairs over 0.005 THD+N Vs. 0.0001 THD+N, it is almost guaranteed that there is little audible difference between the two. Also, you have to more broadly define how it is measured. Small amounts of odd-order are very audible, higher amounts of even order harmonics much less so.Also, you would have to know where the distortion components are in relation to the frequency band. You can listen to 10% THD at 20 Hz and not tell a distorted sinewave from an undistorted one.So... yes, it is more complicated than a simple single number but there is plenty of research showing what is and what is not audible. With transducers, we are very happy to get 1% THD+N at higher listening levels. Those distortion products are both even odd order depending upon the mechanism causing them.I'd say we are pretty safe in saying that those non-linearities swamp those that are another 40-60dB further down. It is like saying you can appriciate the sound of your hifi while using your chainsaw. Nobody would consider that a rational exercise, yet we routinely make such comparisons when judging audio components. The rational person, turns off the chainsaw before they fine tune their audio system for best performance. The irrational person quibbles about the nuances of the performance while ignoring the chainsaw. -- Kevin Haskins Kevin Haskins's Profile: http://forums.slimdevices.com/member.php?userid=30729 View this thread: http://forums.slimdevices.com/showthread.php?t=72246 ___ Touch mailing list Touch@lists.slimdevices.com http://lists.slimdevices.com/mailman/listinfo/touch
