| Stylus Drag Aoliviero - I can only surmise that the power supply and feedback mechanism of the Raven AC is inadequate if it cannot hold the speed. I certainly wouldn't be happy spending that sort of money on a TT and it not being able to hold the speed accura... | |
| Who needs a MM cartridge type when we have MC? The Kebschull preamp uses internal MC transformers for the MC input, and does not represent a high gain tube phono preamp. You may well have a skewed view of the tube world if this was your reference. | |
| Who needs a MM cartridge type when we have MC? On the contrary, some of us are quite sensitive to high frequency ringing and compression in solid state phono stages. It is quite plausible that tube phono stages are more benign in dealing with high frequency resonances generated by MC's. Certai... | |
| Stylus Drag Tonywinsc,The closed loop open loop is not as simple as implied. They are inextricably linked to the motor technology used, AC or DC.DC motors require a feedback or speed control system to actually run. They will not run without it unless you use ... | |
| Stylus Drag My Final Audio TT has a 19kg platter and very sophisticated motor drive, basically a huge AC motor driven by oscillator preamp and power amplifier which reconstructs sine and cosine waves for the motor and provides precise adjustability for both s... | |
| KEF 107.2 with KUBE? KUBE - I AM ABSOLUTELY CORRECT WHEN I SAY THAT EACH KUBE IS CALIBRATED TO THE INDIVIDUAL SPEAKER. If you can find Dick Olshers review in Stereophile vol 9 no 7, November 1986, he discusses the 107 Kube. He actually had DC offset problems with his ... | |
| KEF 107.2 with KUBE? Hi I owned these speakers a few years ago. They sound fine without the Kube but are definitely more accurate with the KUBE. Unfortunately each Kube is adjusted for the particular drivers and individual speaker - left and right. In other words each... | |
| Who needs a MM cartridge type when we have MC? DoverWhere did the resonances come from. Of course you could argue that the resonances landed on the arm via Virgin Airways, or some flooby dust dropping from the heavens was upsetting the arm, but I think the balance of probability is that some c... | |
| Who needs a MM cartridge type when we have MC? OK have a read of the Audio Feb 1987 review of ET2 on Vinyl Asylum.Tests show cancellations of signal at 40hz and 150hz, their view was there were resonances in the arm cancelling the signal at these frequencies.However they also state the air bea... | |
| Who needs a MM cartridge type when we have MC? I suppose you've heard the "solders marching on a bridge" that is able to send it into a resonant mode of undulation, despite the mass differential.Or is that an urban myth ?Have you heard of Newton's Laws ? Kinetic energy ? | |
| Turntable speed accuracy Lewm - I positioned vertically a silver metal marker, about 25mm wide, on the wall - it was quite easy to check the moving distance from the leading edge. | |
| Bergmann Magne True story - a friend of mine contacted Avante Garde in Germany about their horn speakers. He mentioned that he was thinking about getting some new speakers for his birthday in a few months. A few months later he was contacted by Avant Garde with ... | |
| Azimuth observations and importance Ironically azimuth paranoia occurs with me when I use a detachable headshell tonearm, often the bayonet fittings have a little slop. I use the Ikeda headshell on these which has the dreaded asimuth adjustablility via a clamp rather than the grub s... | |
| Turntable speed accuracy Atmasphere - think of all the "wear and tear" of all the drive train over 70 odd years. I think whilst we have gained in technology, we have probably lost ground in metallurgy, it's the age of junk metals ( PC & non toxic manufacturing process... | |
| Who needs a MM cartridge type when we have MC? Henry I have finally managed to test the Final Audio with the Sutherland Timeline.http://forum.audiogon.com/cgi-bin/fr.pl?eanlg&1320876538&openflup&546&4#546 |
