| Helping an amp cope There are some possibilities, one being to add global negative feedback to the amp if it does not already have it. Realistically, you need lower output impedance, which means more transistors in parallel. This means a new amp. If you want great ba... | |
| I need more cowbell.... The majority of components have the same weakness, lack of high-frequency dynamics. This is what gets you the cow bell. This is not frequency response, but transient response. Your components are good circuit designs, all of them and you have obvi... | |
| How Revealing Should a System Be? Different audiophiles have had different experiences with discrimination/detail rendering. I believe most go through a phase where they have achieved lots of detail by changing, cables, sources etc.. only to have it sound clinical or harsh, but al... | |
| please chime in... Lots of audiophiles are using tubes, cables and other tweaks to tame the harshness coming from their digital front-ends. The problem with this is that result is loss of detail, HF/LF extension and usually dynamics. If you get the RIGHT digital fro... | |
| Electrocompaniet vs Krell vs Musical Fidelity IMO, the ECD-1 sounds better than the EMC-1UP. Both have a reverberant, warm quality that results from insufficient power delivery, really strange digital circuit design and S/PDIF not matched to 75 ohms. For a stock component, the ECD-1 is one of... | |
| Best Player or DAC: ceiling $3k For stock DAC's, the Electro ECD-1. Great out of the box, but imaging and sibilance could be improved. For modded DAC's, the Perpetual Technologies P-3A.Steve N.Empirical AudioManufacturer | |
| Mods for a PS Audio HCA-2? The thing that folks need to understand about stock components is that they may have great frequency response with a steady-state signal, but they usually have dissapointing transient response. Mods are the only way to fix this. Power delivery to ... | |
| Why all these JC-1's for sale? The temperature of the JC-1's is overblown. If you are in a small room and leave them on high-bias, then you will need air conditioning. You can always leave them on low-bias until you are ready to use them.Steve N.Empirical AudioManufacturer | |
| Why all these JC-1's for sale? Sean - the bias on my particular monoblocks was not set the same. One was much higher, so I adjusted them to be the same. They still get 20-25 Watts of class A. This misadjustment is fairly common - many have reported more buzz and higher heating ... | |
| Pioneer PD65 needs a DAC Zippyy - The 7000 is built well and makes a decent transport, although not as good as the 7700. I offer a digital mod for the 7000 that is not too expensive to make it a better transport. With the mod, you can safely use a 1m cable.As for DAC's, I... | |
| Pioneer PD65 needs a DAC The outboard DAC will get you the best CD sound. The ECD-1 is very good stock. I recommend it for anyone that is not planning to modify their gear. It does not have good HF extension though. Rather warm sounding.As for the Transport, the PD-65 nee... | |
| Why all these JC-1's for sale? Sean - the draw from the wall should be only steady-state current. If the amp is working correctly then the transients should be supplied by the internal storage capacitance. These transients are what is quite loud. I have experienced no compressi... | |
| Why all these JC-1's for sale? I have not spoken with Richard since I modded them. He's a good egg. I doubt if he cares much. Besides, if it sells more amps, then it's good for him too.Bob - you should come to my room at THE Show next Jan. and hear them. You will not believe ho... | |
| Why all these JC-1's for sale? 5) The amps aren't performing up to snuff due to a lack of available current i.e. each should have their own 20 amp AC line. As such, they blame the amp when there are other problems.I have not had any problems with dynamics running a single 20-am... | |
| Why my system has detail but no body & warm vocal? The other thing that you should consider upgrading is your stock CDP. No stock CDP short of perhaps a Meitner, Accuphase or other equally expensive deck will have a warm, full-bodied sound. |
