| Why is the price of new tonearms so high Perrew, one could use the tape outs of our preamp, but one function of the linestage that most people don't realize is that it must control the interconnect cable as well. In a stand-alone phono section this does become a source of coloration. Tha... | |
| Riaa curve Eldartford, it might be, but in the world of high end, the difference between HIFI and the ability to sound like real music exists in the nuances. That is why there are Teflon caps, high precision resistors, care in grounding layouts, spec-ing out... | |
| Sensitive enough speakers for low power SET Classic Audio Loudspeakers would be another. They make a Hartsfield reproduction that is about 103db and very wide bandwidth, plus the T-1 and T-3 models (which are available in field coil versions) are about 97 db (98 if field coil) but have band... | |
| Why is the price of new tonearms so high Perrew, as T_bone has pointed out, we do make exactly that, continuously for the last 20 years.Its not every day that someone asks about something like that, so I had to ask. Fortunately, operating a cartridge in balanced mode is at least one thin... | |
| Riaa curve Eldartford, you are right about that process, but the producer of an LP would never have the EQ of the RIAA messed with! Usually the issue is a private studio and producer have made a recording. They want an LP, so they send the tape to someone wh... | |
| Why is the price of new tonearms so high Perrew, are you thinking of an all-tube fully-differential phono stage too? | |
| Why is the price of new tonearms so high Dertonarm, I was thinking the same thing, but apparently neither of us could follow her advice. | |
| SET amp w/Neg feedback? Rleff, the key to that is a flat impedance curve. The Avalon Eidelon does that well, as well as most magnetic planars, whose impedance curve has nothing to do with box resonance :)There is another issue- the difference in performance between low i... | |
| Why is the price of new tonearms so high In its day the FR arms were OK, but they have long been surpassed in terms of State of the Art. These days the better arms will be seen to have their bearings in the same plane as the LP, which helps the arm maintain steady tracking forces when pl... | |
| Riaa curve Eldartford, the unit that I use has bandwidth out to just shy of 30K. The electronics have a bit more than that, but not much (they were designed in the late 60s). I don't think you could say that there is a 'typical' cutter, as they are all desig... | |
| Blown woofer from a bad tube? Is this possible? Short answer: no.The speaker is damaged for other reasons. | |
| SET amp w/Neg feedback? Rockadanny, it all has to do with the intention of the designer. In general, if the designer uses tubes its probably a Power Paradigm speaker he created. Voltage Paradigm designers usually use transistors. That will answer the question about 95% o... | |
| Riaa curve Eldartford, when dealing with calibration of a cutting lathe, the speakers are not part of the equation. To answer your question to Raul though: we are, 'we' meaning the people who make this stuff to standards like this. 'We' say its bad when ther... | |
| Riaa curve Eldartford, my cutting lathe has a set of 'pre-emphasis' modules that are in fact the inverse RIAA curves- if you put their output into a phono preamp, the result should be flat.It sounds to me that what you are getting at is that not all cutting ... | |
| Does this animal exist? 6SN7s have a Mu of 18-20- a bit lower than is practical for a phono section. The 6SL7, which is the high gain octal dual triode, can be a bit tricky as it does not sound like the 6SN7- it sounds more like a 12AX7, and is prone to microphonics in t... |
