| Low power tube amp for Sonus Faber? According to a lengthy email exchange I had with Roger Sanders --over 40 yrs of ESL experience -- the jist of what he explained to me is that speakers with a 4 ohm rating will not actually perform at their state SPL range. a 91 db rated spea... | |
| MAC Autoformers? I did read your white paper before entering this discussion. Lets just agree to disagree. Peter Walker designed the 57 to be used with an amplifier with a damping of 20 and even specified the series inductance. To say that these speakers will p... | |
| Autoformers, The Benefits in matching amp to speaker I consider it a device that makes the problem go away.When we introduced our Z-Music autoformer back about 1990, we always regarded it as a problem solver. The same is true of the ZEROs, which is a similar product.Since we make OTLs, the problem t... | |
| Low power tube amp for Sonus Faber? The Sonus Fabers are such a rich, warm speaker I’m not sure that they benefit from the overtones of a tube amp, at least mine, in my room did not. So is this why the company that owns Sonus Faber also owns Audio Research and MacIntosh?It seems the... | |
| MAC Autoformers? @ramtubesRoger, you might want to read this:http://www.atma-sphere.com/Resources/Paradigms_in_Amplifier_Design.phpIf the Quads were close to the wall behind them, they will often have one-note bass. This often happens when a solid state amp is emp... | |
| Low power tube amp for Sonus Faber? If I crank up the volume, am I risking amp to clip and damage my elipsa? No.i really wanna get the amp, I’m in love with it. Imagine putting monster truck tires on a British sports car from the 1950s- if you really want to experience the charm of... | |
| Not enough power what does it sound like? +1 shadorne got it right with a minimum of words.In addition, if a solid state amp is used, your tweeter may be at risk. A classic symptom of an underpowered system employing a solid state amplifier is fried tweeters. | |
| Low power tube amp for Sonus Faber? A lot will depend on your room size and listening habits.The speaker efficiency is about 88 or 89 db 1 watt/1 meter; on paper the speaker is rated with the sensitivity spec of 91 db. But because its nominally 4 ohms, this means that the voltage in... | |
| MAC Autoformers? @bifwynne , Well, since you asked, the answer is ’distortion vs actual frequency response’.All amps make distortion. Some distortions (IMD and higher ordered harmonic distortion) are more audible than others. Of the two mentioned, the latter is wh... | |
| Is there actually a difference? ^^The specs on the amp appear to be misleading. If it were really capable of 150Amps at any time, at the very least it would be making 22,000 watts or more!Constant current mode involves using current feedback rather that voltage feedback, and wil... | |
| Autoformer vs Speaker impedance Curve @ramtubesHello Roger, welcome to the forum. Thanks for your posts!We used to make an autoformer we called the Z-Music autoformer, which had taps for 4,3,2 and 1 ohm loads. With it, Steven Stone of TAS was able to listen to his Apogee Full Range lo... | |
| Autoformer vs Speaker impedance Curve @73max Just for the record, I've nothing to gain if you buy a Mac with an autoformer in it :) However, you if you can find a set of ZEROs (which, so far as I know, are the only outboard autoformers available for this task), I think its a very go... | |
| The 'tube-transistor' enigma by MC carts? @chakster I stand corrected; thanks for posting that link. I've had more than one metallurgist tell me that while 6Ns metals exist, the wire from them isn't actually 6Ns, although it gets called that. Since I do EE work, I went with their expertis... | |
| Tri-Planar Vll "SE Upgrade" @atmasphere the two discs you cut, are those available? IF I never hear the cannons again it will be toooooooooo soon....Some of the LPs we cut are on the Nero's Neptune label. The LP I use for reference was not mastered by us- that was done at th... | |
| The 'tube-transistor' enigma by MC carts? @chakster Just so you know, 6Nines copper wire does not exist. The best anyone has done is 5Nines and that claim seems highly suspect! Another way to look at this is the wire might be extruded from 6Nines copper, but once extruded it won't be 6N a... |
