| Question about length of SPDIF COAX interface cable length That's surprising. Brightness would suggest a presence of the jitter (that translates to added noise). What about clarity/transparency and imaging? It is remotely possible that some electrical noise is injected from the source, possibly thru th... | |
| best way to connect audioengine b1 to my HK3490 receiver. Optical cable or RCA's Yes, optical will deliver all digital data, but since D/A conversion timing is extracted from this data, any changes in timing (time jitter) will convert to noise. It will depend greatly on the quality of digital output as RCA connection will dep... | |
| Question about length of SPDIF COAX interface cable length grm, I'm glad 8" works for you. It is safer not to get reflections to start with then trying to manage them, IMHO. | |
| Question about length of SPDIF COAX interface cable length I would choose 8" for sure. Cable becomes "transmission line" when propagation time (one way) is more than 1/8 of transition time (rule of thumb). Transitions for typical transport are about 25ns. Allowed travel time is about 25/8=3.125ns, equi... | |
| Bettye LaVette I noticed there is no info about recording process. I remember most of older CDs had designation next to Compact Disk logo, like ADD - meaning Analog recording, Digital mixing, Digital media. Some of classical recordings listed exact model of th... | |
| SPDIF cable same as coaxial cable? Does SPDIF just take the I2S format and just change into a single connection instead of 5 connections.No, they are two different formats. The main difference is that I2S contains both data and the clock (separate wires), while with S/Pdif you hav... | |
| Downside to R2R Ladder DACs? George, this is very true - two power supply caps in parallel have smaller ESR, but they also have smaller inductance, often horrible for very large caps. In addition few smaller caps instead of one large cap allows for better packaging (more eff... | |
| Am I too big of a jerk,even for audiogon? Eric, say no to drugs :)Seriously, I think you were always very informative and very far from trolling - one of the very sane people here. | |
| Downside to R2R Ladder DACs? Laser trimmed resistors on the same substrate tend to have similar tempco and aging. While aging can change initial resistance it is very likely to do it in similar fashion (same material) to all resistors keeping division ratios pretty much the ... | |
| Seeking advise/your experience with wanting a to handle CDs/records without damaging them? Important - when cleaning, wipe CD from inside hole to outside radially. Avoid motion along the track. Error correction works up to about 4mm scratches along the track. Above that, up to about 8mm, it will interpolate missing data and it will s... | |
| Seeking advise/your experience with wanting a to handle CDs/records without damaging them? I keep al my CDs ripped on HD with backup copies. That way I can always recreate CD for myself or copy for a friend. There are ways of polishing the surface, but I would first rip it with good program to get perfect copy (I use XLD on MAC with 2... | |
| SPDIF cable same as coaxial cable? AES/EBU - uses an XLR cable that should be engineered to have 110 ohm impedance.Like with S/Pdif, AES/EBU is an audio transfer standard and not the cable. It can be used with 110 ohm XLR cable (IEC 60958 type I), with 75ohm coax or Toslink (IEC 6... | |
| DAC Chips Both chips in PRO version are 2x8 channels. My Benchmark DAC3 sums them by 4 and uses dual differential outputs. That way they use all 16 channels. 9038PRO according to links provided by George, has dynamic range of 140dB, but it is in mono mod... | |
| A Couple Little Things I'm Wondering About Staccato effect? Sure, for people who can hear tiny change in few nanoseconds between supports (hundreds of MHz). Let's assume that somebody can hear the difference. To me it doesn't matter if this difference is real or it is only a placebo ef... | |
| A Couple Little Things I'm Wondering About Sorry, but speed of electricity in the wire is dielectric dependent and is far from the speed of light (around 0.6 of it). In practical terms it is approx. 5ns/m in typical insulated wire and 3.33ns/m in the vacuum.Since dielectric affects the sp... |
