Re: [SlimDevices: Audiophiles] Affordable Audio review of SB3
Yeah I read the review. Very disappointing. That JVC CD player was all the rage back in 1990. 17 years ago! I particularly preferred the McIntosh MCD7007 (using the highly regarded TDA-1541A Gold Crown DAC chip) over the JVC unit back in the day. The SB3, even in stock form, can stand up to virtually any consumer grade CD player made. The JVC was less than $1000 back in 1990, IIRC. The McIntosh unit was twice that amount. As much as I loved my now departed McIntosh MCD7007, I consider the SB3 at least tenfold superior to it. It's that good! -- crooner Customized dual chassis Super Squeezebox EAD DSP-7000 Series III DAC with HDCD and mods.

Re: [SlimDevices: Audiophiles] SB3, best audio quality and sound level
Being an IT person (like others on the forum) I guess I am less scared of some of these digital processes. Upsampling doesn't destroy any information. (Downsampling might.) For example, if you have a photo sized 300 pixels by 200 pixels on computer, and expand it to 600 by 400 pixels, you do not destroy any original information. You just make it bigger. There are various ways of expanding the image. You could create 2x2 pixel blocks exactly corresponding to the original photo. In which case, the photo looks exactly the same, just as blocky, except physically bigger on the screen. Or, you could expand it using a dithering technique which interpolates values for each of the pixels at the new resolution, from values of pixels at the old resolution. Either way, no information has been lost (and I mean none, nada, zip, not a jot) and one may argue that a dithered up-scaled picture might be a more natural representation for the human eye. If it is upscaled in this way, and downscaled in a compatible fashion to the original size, you still get exactly the original photo. Exactly, I mean exactly down to the last 1 or 0! Try it. Repeat the process ten times, a million times. The end result is exactly the same as the original, down to the last 1 or 0. It's just the way it works. (I might add that if anyone claimed to *see* a difference in the end image, it could only be put down to a placebo effect :-p Ooh!) The issue for red book is that the original signal is encoded with a 16 bit word length. Upscaling involves no degradation to the signal, in fact might enhance it subjectively (but not in terms of its content of absolutely accurate original information, which remains utterly unchanged). And if this upscaling is done to a sufficient degree it means that subsequent volume attenuation might still not impact that information content - you still have the original resolution encoded in the signal. (This depends on the level of upscaling, and the amount of attenuation - which is why it's recommended to stay in the higher side of the digital volume range.) If you're not so familiar with IT concepts it sounds scary, but really it does work this way.

Re: [SlimDevices: Audiophiles] SB3, best audio quality and sound level
OK I'll have a go: No, properly implemented digital level control does not compromise or degrade audio quality in a way that a human being (not a calculator) can detect, provided that it is used sensibly - i.e.the level is not attenuated too much. For the SB/TP that means keeping the level within the 80-100 range and using analogue attenuation to make this your normal listening range. By the way, on the topic of upsamplers altering the bits - ignoring the 16 v 24 issue - it is possible that the lowest bit may be altered due to rounding differences - but the lowest bit of 24 is inaudible anyway!. One could argue that altering the 16th bit of 16 bit audio is also inaudible - but there is some debate about this. -- Phil Leigh You want to see the signal path BEFORE it gets onto a CD/vinyl...it ain't what you'd call minimal... ...SB3+TACT+Altmann+MF DACXV3/Linn tri-amped Aktiv 5.1 system and some very expensive cables ;o) Phil Leigh's Profile: http://forums.slimdevices.com/member.php?userid=85 View this thread: http://forums.slimdevices.com/showthread.php?t=38233 ___ audiophiles mailing list audiophiles@lists.slimdevices.com http://lists.slimdevices.com/lists/listinfo/audiophiles

Re: [SlimDevices: Audiophiles] foobar vs. softsqueeze for FLAC playback with ASIO driver
I'm a newbie. I'm experimenting with a similar problem to the original post (comparing sound between foobar using asio drivers and softsqueeze). I have a laptop with foobar2000 and softqueeze installed. My laptop is connected to my Outlaw RR2150 via a USB cable. The Outlaw has a built-in USB DAC -- the UAC 3553B DAC -- so effectively the amplifier becomes the laptop's soundcard). When using foobar2000, there is a large, subjective improvement in sound quality when using ASIO instead of the base USB drivers. I'm using ASIO4ALL with foobar2000 to achieve this, since I have no unique drivers for the USB DAC in the Outlaw (so I think in this case I'm in a different situation than folks with an M-Audio USB DAC for example. I much prefer the SoftSqueeze interface (and hope to buy Slim Device hardware in the future), so I was comparing the SoftSqueeze sound to foobar. On initial comparison, foobar2000 seemed to sound much better. I then tried to setup ASIO with SoftSqueeze, but in the Audio Mixer combo box I'm not presented with options to use ASIO.

I figure a decent line conditioner with dedicated digital filters should do the job. A digital watch radiates noise too, but when have you heard anyone complaining about it? A linear supply radiates noise- look at the waveform at the rectifiers and explain how THAT won't radiate. It isn't a matter of does it radiate- everything does, it is a matter of how much it radiates. It is also a matter of how susceptible other devices are to that radiation. You're going to get a what, $500 line conditioner to theoretically counteract the noise made by a $5 power supply? In this context the guys who spend $300 for a linear supply for the SBs look downright sensible!

Phil Leigh;226156 Wrote: OK I'll have a go: No, properly implemented digital level control does not compromise or degrade audio quality in a way that a human being (not a calculator) can detect, provided that it is used sensibly - i.e.the level is not attenuated too much. For the SB/TP that means keeping the level within the 80-100 range and using analogue attenuation to make this your normal listening range. By the way, on the topic of upsamplers altering the bits - ignoring the 16 v 24 issue - it is possible that the lowest bit may be altered due to rounding differences - but the lowest bit of 24 is inaudible anyway!. One could argue that altering the 16th bit of 16 bit audio is also inaudible - but there is some debate about this. Well, OK - but an analogue volume control turned way down is also bad. The point is, there doesn't seem to be ANY real difference between analogue and digital volume controls, even in principle. In both cases there's simply an issue of S/N. Digital rounding errors - at least in the case at hand - are totally irrelevant no matter how much you turn down the volume because they're always less than the noise. -- opaqueice opaqueice's Profile: http://forums.slimdevices.com/member.php?userid=4234 View this thread: http://forums.slimdevices.com/showthread.php?t=38233 ___ audiophiles mailing list audiophiles@lists.slimdevices.com http://lists.slimdevices.com/lists/listinfo/audiophiles

The point is, there doesn't seem to be ANY real difference between analogue and digital volume controls, even in principle. opaqueice, I am interested in your meaning after reading the guide. If you have time, please read trough this section of this guide : Digital volumecontrols. http://extra.benchmarkmedia.com/wiki/index.php/Digital_volume_control A little quote form the guide :Disasterous distortion can potentially arise when a digital volume control is implemented Binary numbers, just like decimal numbers, do not always multiply and divide evenly. There are often remainders - extra digits that are a result of the multiplication. -- eiret eiret's Profile: http://forums.slimdevices.com/member.php?userid=11521 View this thread: http://forums.slimdevices.com/showthread.php?t=38233 ___ audiophiles mailing list audiophiles@lists.slimdevices.com http://lists.slimdevices.com/lists/listinfo/audiophiles

Hi cliveb, More likely that I am missing something, instead of you! As I understood it, when an incoming signal to an upsampler or upsampling DAC is already 24-bit (like say a digitally attenuated signal from an SB3 S/PDIF output), there may be some amount of word length reduction done immediately prior to the upsampling and re-extension of the bit width by the upsampling algorithm or device. Outcome: Who knows! :) (I haven't noticed any audible result). -- NewBuyer NewBuyer's Profile: http://forums.slimdevices.com/member.php?userid=7862 View this thread: http://forums.slimdevices.com/showthread.php?t=38233 ___ audiophiles mailing list audiophiles@lists.slimdevices.com http://lists.slimdevices.com/lists/listinfo/audiophiles

eiret;226237 Wrote: Binary numbers, just like decimal numbers, do not always multiply and divide evenly. There are often remainders - extra digits that are a result of the multiplication. My point is very simple. Rounding errors like that can only affect the last digit. So the worst thing that can happen is that the volume-reduced result is off by an amount equal to half the 24th digit. On the other hand the last three digits are lost in noise anyway for the transporter (and it's worse for the SB). So the distortion due to noise is always at least 16 times the amplitude of the distortion induced by the digital rounding.
