Loudspeakers - how best to prolong their lifetime?
Besides sunlight, smoke is something to best avoid. As is high humidity and moisture. Many speakers which have foam surrounds can easily have the surrounds replaced, it's not automatically a death sentence. And depending on the brand, it's probabl... 
Is this the END of DAYS for the high end CD player
It's actually the End Of Days for the high end. The patient has been dead for quite some time, he's just forgotten to fall down. 
VTA and cartridge loading
Just to clarify a confusing sentence in my post.."Too little and the peak makes things too bright, and too much and the sound is overdamped." I was referring to damping, not impedance. The lower the impedance the greater the damping is. Almost cou... 
VTA and cartridge loading
I think that you have the VTA part, more or less, correct. But keep in mind that there is only one correct way for a stylus to meet the groove; this is not a tone control.However all cartridges have a high frequency resonant peak. That peak usuall... 
Cartridge life really only 3 years??
Just to address Sparky's comment directed at me, much of this discussion is an oversimplification. Although suspensions do wear out, stylii do not hit some magic amount of use and become groove gougers. Stylii, as seen under a microscope, wear mor... 
Cartridge life really only 3 years??
The Ortofon FAQ states "600 to 1000 hours" of playing time and the JICO FAQ puts it at 800 hours:http://www.ortofon.com/support/faq-installationI'm very comfortable with the 800 hours figure. I think that a lot of people push it because the invest... 
Best surprisingly good value component
My listening room, actually. It's below grade on a concrete slab, covered with carpet. 15'X26'X9'. At first blush, I thought that it was going to be a disaster, but with the record racks and book shelves in, there is a nice mix of reflective and a... 
Benchmark DAC-1 Get The Most Out Of Your DAC-1
The Dautch, I believe that Chris Johnson ran Sonic Frontiers not conrad-johnson (the name is not capitalized). Bill Conrad and Lew Johnson started conrad-johnson. 
How "Rare" are Audio Classics, Really
In early 1947 the first run of Klipschorns were made. These were the only Klipschorns made by the Baldwin Piano Company, under contract from Paul W. Klipsch. Twelve were made, serial numbers 002-013. Of course, being made in the mono era, they wer... 
Establishing a common analog listening bias
I have already explained it in the fourth post in this thread; no need to endlessly repeat things. I will leave that to others. 
Establishing a common analog listening bias
And a really bad try at that. 
12ax7 tubes can be enterchanged with xxx tubes?
There are several ruggedized or industrial grade 12AX7 variants that are less well known and, in many circuits, exceed the performance of the 12AX7. The 7025 is the most common. It is a direct substitute designed for low noise audio applications. ... 
How "Rare" are Audio Classics, Really
Some numbers are readily available and some are more problematic. The LS3/5A was liscensed to a number of manufacturers, Chartwell, Rogers, Spendor, etc. So numbers are going to be hard to come by, but they are pretty common speakers.But take the ... 
Ordering cartridge from overseas
Joe, it's funny that you ask, as I have a mint, late model, totally stock ST-70 as well as the modded one. I only finished the mod last Sunday so things are not broken in yet and I feel a bit funny commenting, so an update will be in order. And I ... 
Ordering cartridge from overseas
Joe, we're on parallel paths, for sure. I finished my complete chassis-off rebuild of my Dyna 70 last week, after nine months. VTA board low gain, Russian PIO caps, Panasonic Electrolytics, German can cap, new paint, triode switches, the whole mag...
