| Help I need to locate a part The NPD5566 is National Semiconductor's version of the N-ch JFET 2N5566You might find Siliconix data sheet here http://www.vishay.com/docs/70254/70254.pdf(Siliconix belongs to Vishay now) | |
| Tone controls- to use or not? Most of high end preamps don't even have tone controls and all amps sold in Best Buy do. This alone should suggest something. Tone control destroys imaging, clarity, and even tone. It changes harmonic structure by improper summing of harmonics (h... | |
| Why do digital cables sound different? Added bits would be extreme case of impedance mismatch. It's more to preserve shape of the pulses to avoid crossing threshols at different times causing jitter. Jitter creates sidebands not harmonically related to root frequency (audible). Even do... | |
| Should repaired equipment be stated in the ad?? People don't reveal repairs anticipating that somebody might be afraid of buying repaired unit. This person would buy something that has, what he considers, a hidden defect (loss of value in his opinion). The fact that they don't know about it doe... | |
| System to system Yes, you can!I'm not sure about tube amp but you can do this with two SS amps connecting speaker between +outputs of both amps and shorting -outs (grounds) together. Since this is a little similar to bridging amps (but no phase reversal) amps have... | |
| IcePower 1000 ASP Board Looks like something is changing. Icepower does not exist as a subsidary of B&O (as of July 2008). Founder of Icepower Karsten Nielsen sold his 10% shares in Icepower to B&O (who owned remaining 90%) and left the company. Nielsens doctorat... | |
| IcePower 1000 ASP Board As far as I know B&O does not sell modules to the public (UK retailer is suspect at least - ask B&O). Amp manufacturers can buy them but minimum quatity is pretty high - in case of my amp module 200ASC it is 792pcs. You might find module o... | |
| Directional interconnect cables Carl109 - I know, it was just a joke. It might be easy to observe that something likely "IS" but much more difficult to prove that something "ISN'T". We just don't know enough. Electromagnetic wave cannot be explained by stack of ping-pong balls o... | |
| Good integrated amp for Paradigm Studio 40? NAD is warm. I run Rowland 102 (same thing as S300) into Paradigm Studio/60 v2 (same tweeter as yours). Sound is on the bright side. I upgrated crossover to no avail (small improvement). Tweeter used by Paradigm in Studio/60 v2 is Vifa aluminum do... | |
| turning my system on during lightning storms Tonywins - I have to fine my receipt and save it. There was warranty as well but I did not treat it seriously. Thanks for the info. | |
| Directional interconnect cables Oh my God - Are you ALL guys SCIENTISTS??? One vodka on ice for me, pleeeeease (always helps in scientific discussions).On the second thought - make it double.Carl109 - There is a huge sound difference between ICs and speaker cables. I tried once ... | |
| Good integrated amp for Paradigm Studio 40? S300 is neutral but studio/40 is a little bright - I would suggest warmer amp. | |
| Directional interconnect cables I'm just merely stating that knowledge of Ohm Law is not enough to question expertise of cable manufacturers - reality is much more complicated. I would rather depend on my ears or conduct experiment.Since we are starting another round I'll have P... | |
| Top resistors Carbon Comp is pretty bad - in addition to noise is nonlinear vs. voltage. Carbon Film is a little better. | |
| OpAmp Swap? Try LM4562 - National Semi got awards for them. Excellent AC and DC spects. New versions of Benchmark use it. It is also dual package. Available in Digi-Key |
