| Best Upsampling DAC??? Need Your Advice Please You should consider the Perpetual Technologies P3-A, which will kick the snot out of all of these with the right mods. The player is around $600 and the mods are around $550. | |
| New Perpetual P1/P3 configuration KR4 - the mods include 11 traces that are cut, 12 components that are deleted and 18 components that are added, plus some point-to-point wiring. Non-trivial, I assure you. Takes at least 8 hours to do it with the right parts, equipment and a very ... | |
| Power cord? Why? Iasi - I understand that Roger contracted Coda Technologies to design the Innersound amp for him. Same guy that designed the Coda and Continuum amps. I have heard from one of my dealers that Roger is not a cable believer, however he does spec a lo... | |
| Power cord? Why? Eldartford - 99% of modern copper wire is oxygen-free. It's mostly marketing bruhaa.. There are a few examples of poor wire, but if you use a reliable source like Belden, Alpha or Carol, it's all good stuff.Now, if you want the best-sounding wire,... | |
| When using Maggies with Crossovers I would suspect that custom cables would perform best, in a separated bi-wire configuration. | |
| optical or coaxial audio cable? I am running both optical and coax from my Sony transport. They are indistinguishable now, but only after I did mods to the digital output circuits to improve jitter. With the right cable, the coax can usually be better, because it avoids the opti... | |
| Power cord? Why? Hbarrel - I will not be driving from Oregon to Akron, sorry. BTW - Power cord effectiveness has little to do with how clean the power is.... See my FAQ page at:http://www.empiricalaudio.com | |
| Power cord? Why? Iasi - I have had the Innersound ESL amp in my system for a couple of weeks. I know the design of this amp (by Coda Technologies) - no negative global feedback, strictly class A/B and lots of protection fuses etc.. - however, you have to be carefu... | |
| Power cord? Why? Eldartford - you can buy hookup wire at: alliedelec.comCopper quality matters, whether it's power IC's or speaker cables. | |
| Power cord? Why? Iasi - what type of power amp do you have? Does it have an AC input filter? | |
| Power cord? Why? "Also, the greater voltage drop in a wimpy power cord does not translate into degraded sound provided that the power supply is robust."So, show me one amp which has a "robust" power supply. I have never run across an amp yet that did not benefit f... | |
| Power cord? Why? You may not be able to measure what you hear. Depends on the noise floor of your sampling oscilloscope. You MUST use differential probing technique for this to avoid ground-loop noise as well. This is not a trivial measurement.You would be better ... | |
| Power cord? Why? TWL wrote: "I'm currently using a large capacity lead acid automotive battery with 650 cold cranking amps, located about 24 inches from my amplifier. I have the terminals directly connected to the power input barrier strip on the amp, with 12ga OF... | |
| Can someone tell me what's going on? The simple explanation is that the output impedance of your source is higher than the preamp output impedance. This is typically the case. Therefore, a low-capacitance IC will have a more profound effect from source to pre than from pre to amp. | |
| Power cord? Why? Batteries, like AC power sources have impedance. Some batteries will have lower internal impedance than others. Some will work well during transient current demands and others will not work as well to provide the transient current. There is no sur... |
