DIY balanced interconnects
Another good value is Belden 8412 - this is the professional standard microphone cable. It doesn't reject hum quite as well as star-quad configurations, but has a lower capacitance, which is a good tradeoff for most line-level interconnect applica... 
are all amps equal
Kijanki, I'm definately with you on this one . . . an interesting comparison is the differnces between these conduction-angles and time-constants between tube and solid-state amps. Tube amps have lossier power transformers, (sometimes) tube rectif... 
Why are most High End Amps class A
Kijanki, we're definately running into some terminological inconsistencies in this field - but if we're talking about very low signal levels, I'd say that the amp in question must certainly be a Class B amp that for marketing reasons was being lab... 
Why are most High End Amps class A
In transformer-coupled tube amps, the physical mechanisms that cause crossover distortion are very differnt from a direct-coupled bipolar transistor amplifier. In a push-pull amplifier (like both the Marantz and Mac), the concern is hysteris disto... 
Solder Pot Advice
I've actually had excellent results with litz wire (including Cardas) simply by cranking my soldering station to a little over 800F, and giving them a good tinning. I then turn it back down to the usual 700F for actual soldering.But if you need mo... 
Why are most High End Amps class A
The term "gm doubling" as I understand it refers to the increase in gain that occurs from when one half of the output stage is conducting, to when both halves are conducting. The idea is that there's "double the transistors", so there's "double th... 
Why are most High End Amps class A
High slew rate input signals come back to summing junction thru negative feedback delayed because of signal path delays. For a moment amplifier has no feedback and overshoot appears at the output (or earlier dependent on design). This will happen ... 
Solder Pot Advice
Solder pots are messy, fumey things -- they take a while to get up to full temperature, and take a big chunk of solder to get them going. Unless you have to tin a hundred wires or something, I wouldn't bother For small-quantity work, a broad tip o... 
Why are most High End Amps class A
The magnitude of TIM is highly dependent on the open loop gain (everything else being equal) up to point where output transistors go to momentary saturation and stay there for a moment (having charge trapped at the junction).No, I think you're get... 
Why are most High End Amps class A
In all my previous discussion about linearity, I have been talking about the performance of JUST the output stage in isolation. And whether or not the output stage is biased as Class A, Class AB, or Class B . . . has NO effect on TIM.The "TIM" acr... 
Why are most High End Amps class A
Actually, not a bad analogy, Kijanki. It's just a question of . . . when do you want the bad news? To deliver more than you promise is usually more exciting than the other way 'round.But with most semiconductor amplifier output stages, the lineari... 
Why are most High End Amps class A
Kijanki, let's look at it like this . . . and this is kinda what I was getting at when I talked about an amplifier being "well suited to the application".A realistic amount of juice necessary to drive most of the domestic audiophile loudspeakers t... 
Why are most High End Amps class A
I am so much at awe with what true Class A amplifiers can do to my life that I just want people to check them out.Spatine, I really don't disagree with you in any fundamental way - it's just that for me, I could say this about a number of differen... 
Why are most High End Amps class A
This may be a more general answer than you're looking for, but I like audio components that both sound good and measure well . . . and do so consistently, under a wide variety of conditions, for many years, without requiring much maintainance or r... 
McIntosh speaker connection questions
Hi Maclover . . . well now things are starting to get hairy. With the setup as you describe it, you cannot listen to one pair of speakers with the equaliser and one pair without at the same time.What I'd suggest you do is to split off the secondar...
