High Sensitivity Speakers
I've tried a myriad of combinations placing my subs most everywhere else, but the symmetrical option has always prevailed; things simply fall into place sonically. Having an array of direct radiating subs around you can certainly envelope one w... 
How do I get the "most" out of a speakers that are rated for 12 ohms?
@barkeyzee1  Your amplifier should be able to make about 150 watts at full power on that speaker.But as Bob pointed out its unlikely that you are actually using much more than a watt or two most of the time unless your room is quite large and abso... 
Why the woofer moves badly when playing certain LPs
The resonance mechanism you and others propose involves forced vibration in which some source of periodic excitation acts close enough to the resonant frequency of the tonearm/cartridge to excite resonant response. This is a plausible explanati... 
High Sensitivity Speakers
@phusis Just to be clear, nowhere did I state that What’s more, "flabby" and "slow" bass as an antithesis to "tight" is hardly a compelling trait as something associated with natural bass. I simply pointed out that overdamped speakers often resul... 
best phono stage under 10k
@sdrsdrsdr  There are quite a few updates available for your preamp! The warranty can be reactivated too.  
Why the woofer moves badly when playing certain LPs
If this theory is correct, a rumble filter or adjusting the tonearm/cartridge resonant frequency would not correct the tracking problem (although I expect the latter would alter the frequency of the bounces).This statement is incorrect. If the ... 
High Sensitivity Speakers
After 15 yrs, speaker technology is still almost the same, although there may have been some advances in implementation brought about by research. Well usually research is how advances are made :)I'm a fan of the Classic Audio Loudspeakers and h... 
new preamp
@keithjacksontucson  If you have a balanced amplifier then a balanced preamp will help you get the lowest distortion out of your amp(s).But most high end audio preamps do not support the balanced standard! The standard is important in that it help... 
Another tube question
JJ makes a blue glass KT88 which is quite nice. 
Seriously considering tube preamp…opinions?
Tubes can add some sweet sounding harmonics to recording that need them. They can also add these harmonics to recordings that do not need them. It used to be said that James Parker of Audio Research specifically added 2nd order harmonics to s... 
Probably the most High End DJ Mixer ever made...
He has a site but nothing like this is on it. Too bad you can't post images here! 
Why the woofer moves badly when playing certain LPs
From viewing the YT video, it appears to me that the arm/cartridge combo is just barely outside of the optimal range and this is borne out by some of the posts above. The thing about this is a slight amount of record warp can really affect the set... 
Why the woofer moves badly when playing certain LPs
^^ My speakers are about 3dB down at 18Hz. We're on the same page with that one.... 
Why the woofer moves badly when playing certain LPs
A certain amount of very low frequency woofer excursion with records is perfectly normal. Just to be clear, my signal chain has 2Hz response from the cartridge input all the way to the loudspeakers, which employ dual 15" drivers. I run them withou... 
Probably the most High End DJ Mixer ever made...
There's a guy here in town named Mark Balma that is building all-tube mixers that look very much like RCA tube studio mixing consoles from the 1950s. They look spectacular!
