Jun 03, 2012	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...
Jun 02, 2012	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...
Jun 02, 2012	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 ?
May 30, 2012	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.
May 30, 2012	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 ...
May 30, 2012	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...
May 30, 2012	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...
May 29, 2012	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
May 29, 2012	Turntable speed accuracy Hi Henry - Have finally managed to try the Sutherland Timeline on the Final Audio TT ( heavy mass - platter 19kg, string drive ( single silk thread ), AC motor driven by oscillator preamp( reconstructed sine/cosine waves) and power amp.Testing wit...
May 29, 2012	Who needs a MM cartridge type when we have MC? Timeltel - Perhaps Henry could denude the Empire for you ?.h?When I was working at a medical company a few years ago they were working on fusing carbon fibre & titanium for use in wheelchairs - now that would be interesting for a tonearm beam.
May 28, 2012	Tonearm suggestions The Audiomods is a modified Rega RB250, albeit with new bearings etc. The arms are quite different structurally.I have actually heard both arms on a Rega P9, the RB1000 was more precise sounding, and to my golden ears cleaner and more articulate, ...
May 28, 2012	Who needs a MM cartridge type when we have MC? Fleib, There are 2 schools of thought here - the wooden spoon and string brigade are trying to dampen energy, others such as Naim Aro, Dynavector are trying to encourage energy away from the cartridge and sink it to ground through the arm/armboard...
May 28, 2012	Problem with turntable/cartridge? Your Benz Micro H2 has 2.5mv output and is designed to run into a MM input. Loading should be 47k.The other thing to check is the VTA, from memory my friends Benz Glider on a Rega required either a 1.5mm or 2mm spacer under the arm pillar to get t...
May 28, 2012	Who needs a MM cartridge type when we have MC? According to AJ Conti changing to a heavier counterweight closer to the pivot point will lower the effective mass - it is counterintuitive. To increase EM you need to split the counterweight into multiples and distribute some weight further back b...
May 28, 2012	Tonearm suggestions The RB1000 is much better built than the Audiomods, but is more difficult to do VTA as it requires spacers under the arm base. For your deck I think the RB1000 will give better performance. I've heard both arms and would consider the RB1000 to be ...
