| Audiophile USB to PCM Edsilva - I look at a PC as a general purpose tool, and a very flexible one. It is like having a set of adapters and sockets with a socket wrench rather than a set of open-end wrenches. The sockets can get into tighter spots and the sockets are in... | |
| Audiophile USB to PCM How is transit stock? Pretty good quality?It only has Toslink out - not so great.Why is the mod necessary and how do we do it?The mod changes the Toslink to coax, improves the edge-rates, isolates with a pulse transformer and matches the impedance... | |
| Audiophile USB to PCM Edsilva - I mod a LOT of different DAC's, and upsampling engines, including the P-1A, Benchmark DAC-1 and the DIP, so I get to hear the output quality of these hardware and firmware upsamplers. The Secret Rabbit Code (SRC) upsampler with Foobar200... | |
| Less fatiquing I agree with Hooper. The amps may be playing a role in this, but it is more likely your source or speakers. Consider upgrading to a Transport/DAC or computer/DAC, which is superior. Mods to these can further minimize sibilance. Some sibilance will... | |
| Please help me for used balanced DAC... Classe' DAC-1 needs major mods to sound as good as these other dacs. The Benchmark would be my recommendation. Very pristine highs, but a bit soft in the mids and lows in stock form. The stock Electrocompaniet ECD-1 on the other hand has great mid... | |
| Black Gate Cap upgrade on Museatex Bitstream DAC "Black Gates are a waste of money."Careful with this advice. There are lots of different Black Gates and lots of different applications. They are certainly not the best at signal coupling, but for LF power decoupling, they are simply the best on t... | |
| old vs new DAC designs and sound differences Arni - I agree, the design and parts quality makes the DAC, as well as the chips. However I have found that cost is not neccessarily the best metric. I have found numerous strange and questionable designs, particularly in the digital areas of extr... | |
| old vs new DAC designs and sound differences I dont agree. Having modded about 12 different DAC's from the early Meridians to the Benchmark, I have found that not only the DAC chips, but the upsampling chips have gotten a LOT better in recent years. You just need to hear the right DAC chip i... | |
| This might be a stupid question,,but 1.5m is the minimum digital cable (AES and S/PDIF) length that I recommend when using a stock transport. This white paper I authored gives the technical explanation:http://www.positive-feedback.com/Issue14/spdif.htmAnd the RIGHT digital cable can ... | |
| Modifying a Pioneer Elite PD-65...... Some older CD units may be better mechanically, but the lasers go out or out of alignment more easily, and the digital electronics is just not as good, including the servos. The DVD players actually have more precise tracking and laser focus mecha... | |
| Modifying a Pioneer Elite PD-65...... I have modded a number of PD-65's. I perform a number of digital and power mods to improve the S/PDIF output as well as installing a modded Superclock3. It becomes a pretty good transport with these mods, and it has the stable platter, which is a ... | |
| A "bit" of information "And the cheap CD drives in PCs don't add jitter when theyread the data on to the HD, and the noisy PC PSU doesn't effect the output signal?"No. I'm talking about ripping the CD and playing it back from RAM on the computer. This is computer-driven... | |
| Transport & tweaks for audio logic 24MXL The first thing you should do, since this is a stock transport, is buy a 1.5m digital cable. This white-paper I wrote explains why:http://www.positive-feedback.com/Issue14/spdif.htmSteve N.Empirical Audiomanufacturer/modder | |
| A "bit" of information Rockvirgo makes an important point. This is why computer audio is intrinsically better than CD playback. The pits are jittery as written on the disk. The Transport also adds jitter when it reads these pits, because each read head has different acc... | |
| A "bit" of information I am an engineer, with 30 years digital design experience, so I'll be happy to give you the technical explanations:1) The S/PDIF output from a transport is specified at 75 ohms characteristic impedance. This means that the output impedance of the ... |
