Tone controls- to use or not?
One more thing. Equalizers used in recording studio adjust each individual microphone/instrument BEFORE mix. They don't equalize mixed stereo image. Correct me if I'm wrong (any sound engineers here?). 
Tone controls- to use or not?
Shadorne - all the sliders on those mixing tables are most likely level control. There are also, as far as I know, Equalizers but extremely expensive (for a reason). Typical tone controls in home amps use pots with very poor matching. As for not c... 
Tone controls- to use or not?
Altering tone always produces sonic degradation because it puts one more element in the chain (even if you set it 0dB/0dB). It destroys clarity imaging etc. For many people clarity/ imaging is the goal - not fun of tinkering. 
Tone controls- to use or not?
"Yes but...the mix engineer and mastering engineer has already monkeyed around so much with what you hear that this "purity" goal becomes a "mute" point."Final product of this Monkeying around is what performer approved and want me to hear. If I c... 
Should repaired equipment be stated in the ad??
I believe that is not so important what I think but rather what possible buyer might think. I don't want anybody to feel bad after purchasing things from me, so I would reveal what I know. If I go by what I think then we enter dangerous territory... 
Should repaired equipment be stated in the ad??
Bdgregory - So you would really select and pay more (worth more to you) for the repaired unit (everything else being equal). Are you serious? Or maybe when you find out that you bought repaired unit you should call seller and thank him for that (h... 
To bi-wire or not to bi-wire?
Musicnoise - with normal hearing, one can hear intensities from 0 dB to 140 dB. This corresponds to power ratio (defined as ratio of the highest audible intensity to the lowest audible intensity) equal to 100,000,000,000,000 - I would call it incr... 
To bi-wire or not to bi-wire?
I would like to add 2 other reasons. One is skin effect that starts at gage 20 at 20kHz. Many woofer cables use gage 7 to preserve low impedance (damping factor). Second reason are the Eddy currents, generated by speakers, getting from speaker to ... 
LCD TV - Are they reliable ?
I have to defend DLP. I have Samsung 42" DLP since 2001/2002 and had to replace bulb ($200) only once (rated 8k hours) running TV practically 6-7 hrs everyday. Bulbs are cheaper now. It has matte screen (while plasma is very shiny) that does not b... 
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...
