solid state vs tubes
MrT, there was a time when planars ruled the roost when it comes to resolution. That time has passed- there are a good number of cone systems now that easily compete with the best planars.However, my comments were more the point that if you had a ... 
solid state vs tubes
Unsound, in this case Mr. Norber was telling me, as did the other manufacturers, that indeed their amps do sound better into higher impedances, despite making less power.The Mac autoformers are used to load the transistors at a lower impedance if ... 
solid state vs tubes
Unsound, Paul Speltz who makes the ZEROs has a letter from Steve McCormick, in which Steve asserts that his amps, which have no problem with 4 ohms at all, sound better driving 4 ohms through the ZEROs.Upon hearing about this (which was about 2 ye... 
solid state vs tubes
Aren't 4 ohm loads more problematic for tube amps in general? Isn't that part of teh [sic] reason why you advocate 8 ohm or higher speakers for use with your tube amps?This is true. The fact of the matter is that **all** amplifier technologies sou... 
solid state vs tubes
Hello Unsound, you can see the issue in the curves of most semiconductors, perhaps easier when you compare input capacitance to current.At any rate, its easy enough to hear! Get a set of ZEROs and a 4 ohm speaker, listen to the difference when dri... 
SET Amp question
If you have questions about how an SET or other 'current source' amplifier will drive a speaker, maybe this link will help in understanding what is going on:http://www.atma-sphere.com/papers/paradigm_paper2.html 
solid state vs tubes
Magfan, here's a nice nutshell explanation that touches on this subject.That there are capacitive elements of semiconductors should not come as a surprise to anyone- most tuners these days do not rely on variable capacitors to tune the station, in... 
solid state vs tubes
MrT, there may be another way to do this. The Quad has a low impedance at high frequencies and a lot of transistor amps will tend to make more power due to that, part of the reason why they sound bright on the ESLs and with less bass impact than m... 
The "great" sound of reel to reel explained
People don't want neutral sound - just look at Audiogon posts how many people seek warm sounding gear or ask how to make sound warmer. One person started thread asking how to make sound warmer and less detailed (I advised blanket over speakers)Kij... 
The "great" sound of reel to reel explained
Right. The first has nothing to do with my comments as it addresses a different issue of digital gear. The second does bear some relevance and does not contradict the findings that GE made in the mid-60s. 
The "great" sound of reel to reel explained
It is also common fact that most Audiophile find equipment "clinical" or "analytical" sounding often are the same with low THD and great linearity measurements. You can arrive at the logical conclusion right????Carlos, not to put to fine a point o... 
The "great" sound of reel to reel explained
It was not an analogue versus digital, which sound better? article; but rather and article concerning why added distortion, by way of phase manipulation and harmonic enhancement/restructuring, has pleasing effect that many qualify as sounding "bet... 
The "great" sound of reel to reel explained
No doubt! But it extends to anything that can draw significant power- and bigger transistor amps can! Imagine the peaks just... not... making it.This taught us a lesson... when we set up an amplifier for test, we test the AC line voltage from the ... 
Overpowering Speakers
Given a choice, I will take the bigger amp any day. You run less risk of damaging the speaker! A smaller amp, if overdriven, is how most tweeters in the world get damaged. In fact, if the tweeter is damaged in a speaker, the repair technician shou...

Carlos269, upon reading this article I am struck by the simple fact that the guy who wrote it must have an atrocious monitor system! -and is either partially deaf (common with engineers in the studio) or simply has no idea which way is up. I too h...
