[SlimDevices: Audiophiles] Re: Squeezebox 2 - Subtle noise and distortion.
In a spare moment I have installed and tested SlimServer 6.2.1 on Windows XP. I can confirm that this platform does not suffer from the noise I have heard when using SlimServer on Linux. As such this problem appears to be a Linux-specific issue, although I do not own a MAC so am unable to test on that platform.

[SlimDevices: Audiophiles] Re: Volume bug - can you really hear it?
FWIW - I have been following the new volume vs sound quality issue. I also thought that my SB2 lost some sound quality at some point. My setup is: SB2 analog - Parasound HCA-750 - Paradigm Studio 20 v3. I was using the 6.1 final release, and just installed the latest 6.5 nightly (slimserver-2005_11_26-1.noarch.rpm on Cent OS 4.1). My totally unscientific / not blind opinion is: the sound quality is back to what it was before the new volume issue raised its head. The best way that I can describe the old new volume sound was flat. I especially notice the difference in cymbals and other high frequency sounds much better now!

Hi Mac, The analog output stage mod that I performed on Jim Holtz's SB2 has nothing to do with jitter improvement. It is about using the internal burr-brown dac and taking its voltage output directly to the RCA jacks via a very high quality signal coupling capacitor. This bypasses the opamp in the output stage, stock signal caps, resistors in the path, etc. The improvement in sound quality is VERY noticeable (assuming you use the analog outputs, of course). Until you at least hear it for yourself and compare it to the stock unit, it doesn't make sense to call someone's opinion of it as audiofool hyperbole. Don't you agree? Thanks, -- Vinnie R.

Hi Mac, The advantages of using the PCM1748KE dac are: -- 6dB improved SNR -- 6dB improved Dynamic Range -- Improved THD and channel separation specs (I don't remember the figures off the top of my head). Whether or not you will hear the improvement depends on your system, hearing, etc. I trust my ears and my customers really like what they hear from their modded squeezeboxes, so that is all that counts to me. Regarding the Toshiba 3390, I am not familiar with this model (do you mean, 3950, 3960, 3980?). Have you even heard one of these that I myself have modded, or was it a stock unit? If it was a stock unit and you were disappointed in it, this has nothing to do with me or my Squeezebox mods. If it was modded by someone else, there is no way of determining if the mods were made correctly, if the soldering quality was good, etc. Regardless, this has nothing to do with my Squeezebox mods... As far as converting to battery power, your statement that properly engineered AC power is far better is simply false.What type of batteries did you experiment with? How did you implement the conversion? Did you even hear a battery modded Squeezebox that I offer? Again, how can you make such general statements? They provide us with very little value and lead to confusion. I have received feedback from MANY satisfied modded Squeezebox customers who would beg to differ on your comments, especially since you haven't even heard any of my work (or have you?).

Thanks Sean. 1V is about a volt and a half shy what of what it takes to drive my power amp. I also assume that bypassing the audio output opamp raises the source impedance to some degree, which may have an added impact in its ability to drive a power amplifier. As you mentioned, the loss of the two pole filter by Vinney's mods goes against the manufacturers' application notes: -Delta-sigma DACs use noise-shaping techniques to improve in-band signal-to-noise ratio (SNR) performance at the expense of generating increased out-of-band noise above the Nyquist frequency, or fS/2. The out-of-band noise must be low-pass filtered in order to provide optimal converter performance. This is accomplished by a combination of on-chip and external low-pass filtering. Figure 27(a) and Figure 29 show the recommended external low-pass active filter circuits for single- and dual-supply applications. These circuits are second-order Butterworth filters using a multiple feedback (MFB) circuit arrangement that reduces sensitivity to passive component variations over frequency and temperature. For more information regarding MFB active filter design, see FilterPro MFB and Sallen-Key Low-Pass Filter Design Program (SBFA001), available from the TI Web site at http://www.ti.com.- http://focus.ti.com/lit/ds/symlink/pcm1748.pdf -- mac mac's Profile: http://forums.slimdevices.com/member.php?userid=932 View this thread: http://forums.slimdevices.com/showthread.php?t=18491 ___ audiophiles mailing list audiophiles@lists.slimdevices.com http://lists.slimdevices.com/lists/listinfo/audiophiles

While the Burr-Brown dac used is not the most expensive dac chip on the market, I really like its sonic signature (nice choice!), especially without the opamp after it.

When I was taking EE classes (way back in the dark ages) we were shown and measured how tube amps add all sorts of distortions and evil stuff, along with not being close to linear across the 20-20kHz band. But now the audiophiles have defined it as good distortion. Breaks my brain. Then years later, I started playing electric guitar, and bought a tubed amp because electric guitars sound better with some tube-type distortion. But that is for making music, not reproducing it.

[SlimDevices: Audiophiles] Re: Volume bug - can you really hear it?
That means that -35dB corresponds to a volume setting of 12 in the SB 0-40 volume range. I believe you'll find the changeover is at 16 on the 0-40 range. That's what the measurements indicate - below this value the old and patched code measure identically. Andy. -- Andrew L. Weekes Andrew L.

It isn't to save disk space, which as you say, is nearly free. Flac and other formats include very important things like error detection and tags so you can know the artist/ album/song. And since FLAC is free and supported by all squeezeboxes, the only downside is a small amount of time once after ripping to compress and tag. And not even that if you have EAC set up right to rip, convert, *and* tag in one operation.

highdudgeon Wrote: Hi -- I just purchased a new Maxtor 300gb (279 usable) HD for use with my SB3. Question: how many CDs, of average length, say, will fit on the thing? Here's another data point, for what it's worth... My library of about 400 CDs averages 0.285 GB per CD. It' encoded using FLAC with the default compression level. The makeup of the CDs in the library has some bearing on how much compression you'll see with FLAC - simpler music (like a jazz piano trio or acoustic guitar recording) tends to compress better. Also, a lot of older jazz reissues and classic rock albums tend to be fairly short, with many under 40 minutes. Other libraries will no doubt see a number larger than 0.285 GB per CD. You've seen that the manufacturer's stated drive capacity differs from the real capacity in (binary) gigabytes. The difference is that manufacturers use 10^9 instead of 2^30, so multiply the stated capacity by 10^9/2^30 (about 0.931) to get the real capacity. CDs on drive = manufacturers_drive_capacity x 10^9/2^30 / gb_per_cd For a 300GB drive, approximately: 300 x 0.931 / 0.285 = 980 -- JJZolx Jim JJZolx's Profile: http://forums.slimdevices.com/member.php?userid=10 View this thread: http://forums.slimdevices.com/showthread.php?t=18552 ___ audiophiles mailing list audiophiles@lists.slimdevices.com http://lists.slimdevices.com/lists/listinfo/audiophiles

Can you give us some more information? Are you using a preamp? What speakers are you using? Any noise when paused or distortion when playing like the original poster?
