Re: [SlimDevices: Audiophiles] Meridian CD player
ralphpnj;580707 Wrote: One quick question: Does this problem happen with all CDs or just with CDs that you've burned yourself? I ask this question because many older CD players do not read burned CDs very well. If this is the case try burning the CDs at a slower speed (say 4X) and see if that helps. Of course if the problem is occurring with both burned and commercial, i.e. store bought, CDs then follow some of the advice already given in other responses. Hi there, unfortunately it happens with all cd's - with the exception of one brand new one which it plays ok ! don't understand why ? all my collection are in reasonable / good condition -- pkfox When the going gets weird - the weird turn pro.

Re: [SlimDevices: Audiophiles] Transporter digital out won't sync with DAC at higher than 48kHz
jfeldt;580567 Wrote: Hey guys, I just wanted to give an update: using the loop mode worked with 24/96 material and either coax cable I had on hand, both via RCA and BNC. I still can't get a lock on my Theta DAC using the original cable or a Kimber DV-75 that I also have on hand for highres material. The Transporter is new, but open-box so used briefly by some other customer from Crutchfield and unmodified as far as a quick visual inspection goes. Mnyb, the higher sampling rates work fine out of the analog outputs. Theta has gone through an ownership change and I'm fairly certain they could care less about my DAC at this point :( I spent a little time doing a few A/B comparisons between the analog output of the Transporter (with the same power cable as my digital lens and with the same analog interconnect) compared to a SB3 into a Genesis Digital lens to the Theta DAC and end up preferring my previous Theta signal chain for redbook material, and still even prefer the Theta playing redbook over the transporter playing 24/96 versions of albums I have highres versions of, though the difference is closer there (and the masterings are different between the 16/44.1 and 24/96 versions and I'm too lazy to trick out my convert.conf to resample the 24/96 down and compare, which I did a few months ago when I had the touch). To me, the Theta has more realistic timbres, much better soundstaging, and is more dynamic. I want to love the Transporter, since it would save me some money over keeping my Theta DAC and Genesis digital lens and it would also simplify my system, but I feel I'll probably be returning it soon. I still need to compare its digital output to the lens' output for 16/44.1 material, and I'm still hoping I'll figure out a way to run 24/96 to my DAC from it before the return period is up. So you're the one who snatched up that Crutchfield transporter? I had my sights set on it but it was sold. Got mine from Ebay. When I try to play a 24/96 file I get decoder out of memory myself but I later read that happens if you try to play a multichannel 24/96 file. -- sxr71 sxr71's Profile: http://forums.slimdevices.com/member.php?userid=18773 View this thread: http://forums.slimdevices.com/showthread.php?t=82341 ___ audiophiles mailing list audiophiles@lists.slimdevices.com http://lists.slimdevices.com/mailman/listinfo/audiophiles
Re: [SlimDevices: Audiophiles] Stereophile Review II: What conclusion can be drawn from the Measurements?

Soulkeeper;578864 Wrote: I don't know the answer to that, but it seems to me that your example has a DC bias. If we define origo (zero) to the middle then the signal would probably vary between 128 and -128, or 32 and -32. (Or if you define origo (zero) to be all bits=zero then 128 would be the middle (silence), and the signal would vary between 256 and 0, or 160 and 96.) Or perhaps I misunderstood you completely. :P It's often easier to have a DC bias from an electronics point of view as it makes the understanding a tadge easier. However on an 8 bit system it would be +128 and -127 as the left hand bit represents the sign bit and +128 to -128 would require 9 bits (the extra to represent the -sign on an 8 bit word). You are on the right tracks though in your understanding. -- Waldo Pepper Waldo Pepper's Profile: http://forums.slimdevices.com/member.php?userid=39029 View this thread: http://forums.slimdevices.com/showthread.php?t=82050 ___ audiophiles mailing list audiophiles@lists.slimdevices.com http://lists.slimdevices.com/mailman/listinfo/audiophiles

adamdea;578884 Wrote: If you reduced by 24 db would you get 8 8 8 9 8 8 8 8 8 7 8 8 8. (I said 24 db because you said it was a 6 db reduction in your example but I confess I don't understand the 6 db equivalence. I just mean getting quieter to the point where the peak becomes 9 and the trough 7) 6dB is often used as as +6d dB is a double in signal level and a -6dB is a halving in signal level. The dB is derived from the logarithmic scaling of signal levels. Decibel scale is logarithmic (to understand logs you should have paid more attention at school::) A decibel is 10th of a bell, but is a measure of power which is proportional to voltage squared that comes out as 10 * it's square ie 10*2=20. (school stuff:) 20 log 2(twice the amplitude) = +6db 20 log 1/2 (half the amplitude) = -6dB. So the OP using 6db plus or minus is a good analogy. -- Waldo Pepper Waldo Pepper's Profile: http://forums.slimdevices.com/member.php?userid=39029 View this thread: http://forums.slimdevices.com/showthread.php?t=82050 ___ audiophiles mailing list audiophiles@lists.slimdevices.com http://lists.slimdevices.com/mailman/listinfo/audiophiles
