Balanced ----- Unbalanced----
Herman, the phonograph is a very low output signal. MC cartridges are lower output than any microphone, even ribbon mics. Almost all cartridges are a balanced source; with output levels that low there is in fact a benefit to be realized in the hom...

Herman, before balanced line occurred, you had to scream at the top of your lungs to make a call across the state. The fact of the matter is balanced line was a transformation because there was less information loss. Historically you may find it u...

Hi Herman, for cables alone the topology is indeed better. Before balanced line came along, transcontinental phone calls were impossible. HiFi did not exist in recordings. Balanced line operation transformed that. Even in short runs that you see i... 
Tube amp speaker output 4 ohms VS 8 ohms
FWIW the 4 ohm tap is there so you can load the tubes correctly. The tubes are likely wanting to see about 3000 to 5000 ohms from plate to plate and your speaker is much lower.The transformer does exactly what it says it does. It transforms impeda...

Herman, the reason we make balanced equipment stems from my experiences in college, setting up Neumann microphones in the music hall. We ran 150 feet of interconnect. That's not something you can do with single-ended- too much high frequency loss.... 
searching balanced Tube preamp with.......
Many tube preamps have a low output impedance that will drive 20K- but not at all frequencies. This limitation is imposed by the output coupling capacitor. The problem is, the bigger you make the cap so it can play bass, the less transparent the c...

It better than nothing! If the balanced standard is supported, then at least the connection between the preamp and the EQ is solid, even if the connection to the amp is only single-ended. The more information you don't loose, the better.

Our MP-1 has a low output impedance- it has a patented direct-coupled output and can drive 32 ohm headphones quite well.It was intended to support the 600 ohm balanced line standard. You may already know this, but the low impedance standard was cr... 
Tube Preamps...I'm sold
The demag device ran an audio waveform- not DC. 
best preamp ever - cost is no object
Hi Carlos, indeed I've seen a lot of studio-intended tube devices that take advantage of variable saturation and the like. I've also seen a lot of studio equipment in general- while studio gear in general is often built to a higher level physical ... 
best preamp ever - cost is no object
Carlos269, having serviced out a few Cellos in the past I was amazed at the poor parts quality. Yes, they are junk, nicely packaged and nicely built. With a price tag to throw you off.FWIW using a variety of NOS tubes to tailor sound is not merely... 
best preamp ever - cost is no object
Carlos269, one of the things that all tube equipment manufacturers face nowadays is that tube quality is nowhere near what it was 30-50 years ago! The EH tubes in the Einstein are a good example- nicely packaged but the tubes are microphonic, nois... 
efficiency- hope i spelt that wright.
Some of the issues regarding amplifier vs speaker selection are discussed here:http://www.atma-sphere.com/papers/paradigm_paper2.htmlMy own feeling is that if the efficiency of the speaker does not interfere with the revealing nature of the speake... 
tube pre suggestion
Take a look on the Audio Horizons threads. I don't think you can beat their preamps, and you get to try them for free.Of course you can beat them! But they are a great deal for the money.
