| System that sounds so real it is easy to mistaken it is not live I think Mr Volti was a furniture maker before he went into the loudspeaker business. His cabinet work is certainly first rate. | |
| System that sounds so real it is easy to mistaken it is not live dogberry, No one, least of all me, is dismissing full range ESLs. That’s exactly what I listen to in one of my two systems, Sound Lab 845PXs, with no subwoofer. One reason for no subwoofer is my disinclination to clutter up the listening room any ... | |
| System that sounds so real it is easy to mistaken it is not live Mijostyn, I appreciate your unequivocal convictions on nearly all things audio, but don’t you think you’re a bit over the top or around the bend in subwoofers? The ONLY worthwhile design is the dipole??? Really? I do like the idea of the dipole th... | |
| SUT - electrical theory and practical experience Drbond, transformer theory is a deep subject. The only person with deep knowledge who ever posts on Audiogon is Dave Slagle (Intact Audio). Otherwise you are not going to find enlightened discussion here. I suggest you do an internet search. The s... | |
| Simplest Linear PSU? Regulation done right typically reduces noise. Done wrong or badly or with defective parts, I suppose it could add noise. Even for a home built LPS, there are excellent prefabricated regulators available as add on devices. Most important is to pla... | |
| System that sounds so real it is easy to mistaken it is not live We once calculated that my speakers have about 400 in.² greater radiating area then do yours. Perhaps that’s where our results differ, because my speakers are not perceptibly distorting in anyway at 100 Hz. And there is the added value of coherenc... | |
| SUT - electrical theory and practical experience My Johnson is very quiet without a SUT, speaking for myself only. But seriously folks, Ralph (Atma-sphere), you have often mentioned the notion that high gain phono input stages need to be designed to be insensitive to RFI. What design elements ... | |
| Simplest Linear PSU? Regulation done right reduces noise on the supply, rather than adding noise. | |
| Stylus skipping at beginning of record Even zero AS ought not to cause your problem although I’ve never used your particular tonearm. One has to wonder why your “technician” left you with zero AS, however. Usually zero AS causes noticeable distortion especially in the R channel. I adju... | |
| Simplest Linear PSU? Building a good LPS is or can be a little more complex than implied. It helps to have an oscilloscope to analyze the performance, too. Learn about pi filters, etc.Also, you may want to regulate the V output in which case you design for a higher V ... | |
| System that sounds so real it is easy to mistaken it is not live SL used to make and sell a single huge ESL woofer panel to be placed in between a pair of their largest speakers, then called the A1. They also made add on wings for the A1, to attenuate the back wave and reduce cancellation. That becomes less nec... | |
| SUT - electrical theory and practical experience "Are there any inherent weaknesses in a SUT versus a transistor, or vice versa?" If I didn't know you were serious, I would suspect you of being a troll based on this sentence. The question has already been broached here in this thread. Elsewhe... | |
| SUT - electrical theory and practical experience "One practical consideration is you really need a very short, low capacitance run of cable from SUT to phono stage." Which is a good reason for having a high quality SUT built in to the phono circuit, on board. | |
| SUT - electrical theory and practical experience Raul, By "passive", I only mean that it does not require or consume external power. OK? You can use any other definition you want. | |
| SUT - electrical theory and practical experience Of course to alter AC line voltage a step down transformer of the kind you own must be inserted into the AC line. That’s precisely analogous to inserting a SUT between a cartridge and an MM phono stage in order for it to do its work. Both are pass... |
