| Jitter issues with dacs.... Jitter is a problem with virtually all Transports, particularly stock. Jitter is also increased with lossy S/PDIF cabling. It is aggravated by systems that are not properly impedance matched as well.I can only speak for myself - I can plainly hear... | |
| Looking for an outstanding DAC Why don't you mod the transport? | |
| Perpetual Tech. gears The P-3A uses 9V AC. The P-1A uses 12V AC. You would have to modify the circuit board to insert DC. | |
| Interconnects: Silver, Copper or Silver Plated? Bear hit the nail on the head and I agree with his analysis completely. To make a high-performance interconnnect, it takes geometry (to optimize R,L,C), optimized dielectrics to reduce dielectric absorption and finally good metallurgy (this can be... | |
| Tube or solid state CD player Also check out this Shanling:http://forum.audiogon.com/cgi-bin/frr.pl?rdgtl&1081629290&read&3&4& | |
| Digital jitter and disk treament tweak Laziness - I doubt that. The problem is how to deliver all of the current features of typical CD players and use a cache-based system to do it. This is not a trivial exercise. The buffer management must be done with an imbedded processor to get al... | |
| Digital jitter and disk treament tweak Eldartford wrote:"The serial data would go into a buffer register and then clocked out at a perfectly uniform rate. Perhaps the common CD player is not built this way, although I can't imagine why not."You are correct that this technique would yie... | |
| Impendance - Resistance & the story of "Z" Sen - good job, however mentioning characteristic impedance is also useful. For low-frequency analog signals, impedance is important, because is represents AC resistance. For high-frequency signals, a phenomenon know as characteristic impedance co... | |
| Can sibilance be eliminated? Stehno - I have no audible sibilance in my CD playback system. I also recently modded a Shanling T200 and the sibilance is gone... | |
| Transport for Scott Nixon Tubedac+ No stock transport compares to an old EA modded Sony DVP-S7700. Stock transports have very slow risetimes and are not matched well to 75 ohms. | |
| suggestions for top quality CDP running direct The only CDP that I have found that delivers the same magic as my reference separates is a Shanling T200 with the full Parts Connexion mods and the EA Turbomod. Really superb from both the SS and tubed outputs. Cost is really high at around $6500 ... | |
| Looking for a DAC change The Electrocompaniet does not make a good transport. You can do much better. The internal DAC is fed by the same signal as the S/PDIF jack - not a good design. I have modded these and made them the best transports I can (perfect waveform, perfect ... | |
| Best sounding op-amp S23Chang wrote:"After done much research, I found the AD8620 has the best spec."Specs don't tell all. The on-die power delivery is what makes a great op-amp. | |
| Would an external DAC improve the sound of my SONY Medium to high-cost Sonys make great transports once they are modded properly, particularly the DVP-S7700. My personal DAC favorites are modded Perpetual P-3A and modded Birdland Odeon-lite. | |
| Best sounding op-amp Op-amps do vary a lot in sound, particularly because of the power delivery on-die and on-package. Some parts are power starved from the get-go and need a lot of decoupling capacitance very close. Others are designed well for power delivery and nee... |
