Horn based loudspeakers why the controversy?
My first my first encounter with horns were Klipsch La Scalas driven by early transistor amplifiers. Not pleasant—but great party speakers. Ditto classic Klipschorns. Never heard these with any kind of tube amp, let alone an SET. Fast forward 30 s... 
Can a Quality Full Range Speaker be the Limiting Component in a system?
Well, certainly, if the speakers match the room poorly. (I am assuming, for purposes of your question that the “quality speakers” are not dynamically limited, are capable of undistorted low bass to 30 Hz and have a treble response to 20 kHz.) Ever... 
power cords with active shielding
Regarding induced current in the “neutral” conductor, one reason to use balanced power is that both the “hot” and neutral conductors are energized, each at 60 volts, but 180 degrees out of phase with each other. This not only avoids the induced cu... 
Sub Integration
Well, first it probably would be better to stuff the ports of your main speakers.  Go to a drug store or similar place and buy a pair of women's ankle-high nylon stockings.  Then go to Home Depot or similar and buy a small amount of rolled up fibe... 
THE LITTLE BLACK BOX, 399.00 ABSOLUTLY NUTS
I’m trying to follow all of this and be helpful. I have a VPI table and unipivot arm, about which I have no complaints. But that’s not the issue.  The issue is that your phonostage has balanced (XLR connector) inputs and the VPI signal block on th... 
For tube sound, which is more important: preamp or power amp?
What do you mean by "tube sound?"  I think tube preamps are great because small signal tubes don't "age" much, so they're sound does not change.  I think, done right, tube preamps provide a greater sense of "articulation" or "naturalness" (i.e. ab... 
Power Conditioner Advice please...
Some people report that power regenerator limit dynamics. The peak current demands of power amplifiers can greatly exceed their nominal rating. I have been very pleased with the performance of my Equi-tech 1.5 kVa balanced power supply. Essentiall... 
Who needs a MM cartridge type when we have MC?
Whew!  Regarding MCs, if you have noise, then you have a problem and it’s not the cartridge. The problem is multiple grounds, aka “ground loops.”  In chasing these suckers down, I’ve discovered, for example, some manufacturers connect one of the s... 
Speakers are the first piece of the puzzle
Well, you have to start somewhere! First, you have to have a room. This seems obvious, but don’t laugh. Consider the size of the room, what other uses are going to be made of it, how much room do you have for audio stuff. For example, my all-time ... 
New Yggdrasil - First (and second) Impressions
Some changes are hard to hear. I had that experience with speaker cables, years ago. While many components need to have been powered up for awhile to sound there best, I’m personally skeptical of a break-in phenomenon with a piece of electronics. ... 
KEF LS50... The ultimate anal-ytical speaker for living rooms?
I just bought a pair of these.  I’m in the process of installing my system in a new house, but I couldn’t resist doing a quick and dirty hookup to my BAT VK-300x integrated amp and Sony SACD player. Sitting on a shelf about 10 inches in front of t...
