| Turntable Upgrade Advice Needed Rega P9 or Oracle I had a mate with a P5 with groovetracer mods, separate power supply and Shelter 501. He tried the Rega P7 and it was no better. He bought a P9 which was a significant improvement. If you buy a P9 make sure you get the RB1000 arm as it is much bet... | |
| Direct drive vs belt vs rim vs idler arm Richard1) The 0.0008% speed impact from stylus drag I measured on the Final is insignificant in the context of the other issues raised such as eccentric records etc - the ones you believe are spurious. The measured speed change is less than the wo... | |
| Cartridge gain overload - please explain I think somebody is confused here.Using the balanced OUTPUT of the LS25 increases the gain by 6db.I presume you plug the phono stage into the INPUT, at least I hope so.There is nothing to suggest that using the balanced INPUT on the LS25 increases... | |
| Who needs a MM cartridge type when we have MC? 8 Reasons not to load a MC transformer - Loading the secondary of a transformer can induce ringing. Loading the secondary of a transformer will move the transformer out of its intended operating parameters. For example Rauls AU340 has been designe... | |
| Who needs a MM cartridge type when we have MC? Ecir38 - no - I'm right. The step up ratio's are 1:10 ( 40ohm input ) and 1:33 ( 3 ohm input ). You divide the preamp input impedance by the square of the step up ratio to calculate the load seen by the cartridge.There is no 4k resistor as Raul sa... | |
| Direct drive vs belt vs rim vs idler arm Richardkrebs"The perfect TT has absolute speed stability under all load conditions"I would draw your attention to the following :Newtons Second Law of Motion - Force = mass x accelerationor Acceleration = Force/massIn other words deceleration due ... | |
| Who needs a MM cartridge type when we have MC? Raul - I did similar mods to a Denon AU320, and to be honest it didn't help much. There are much better transformers than those. The best I have is a pair of matched Altec 4629 microphone input transformers strapped for maximum gain, cartridge see... | |
| Who needs a MM cartridge type when we have MC? Raul - if you double the input value on the MM RIAA then you will double the impedance seen by the cartridge. In the case of the AU340 the impedance seen by the cartridge is 3ohm tap 100k/(33x33) = 92ohms ( 33 is the transformer gain for this tap ... | |
| Who needs a MM cartridge type when we have MC? Lewm I acknowledged that the relationship between the DL103 and the MD was "rumored" Your last post on the subject on the 11th included the words -the fact that the MD was derived from the DL103 This is what I objected to.Now you change tack again... | |

| Eminent Technology ET-2 Tonearm Owners Nandric - I'm an honorary member of the ET2 club having owned one for many years since the 80's. Unfortunately in a moment of madness I gave it to a friend who bought my old Roksan TT. It will come back eventually. | |
| Direct drive vs belt vs rim vs idler arm Yes I imported & distributed SOTA in this country about 25 years ago. | |
| Who needs a MM cartridge type when we have MC? LEWM - There is NO PROOF that the MD is a 103 or based on it. You keep presenting the assertion "that the MD is based on a 103" as a fact, again and again, but it is unproven.Speculative discussion on a forum does not constitute proof. Do you have... | |
| Eminent Technology ET-2 Tonearm Owners Thanks Chris - I would take up your offer, but alas I cant get the ET back yet. I am having to play the long game on this one. I would be happy to throw it on the Fidelity Research FR64S/Dynavector DV501/Naim Aro if you are interested. | |
| Direct drive vs belt vs rim vs idler arm Lewm - the "cogging" mostly showed up as instability, most apparent in the bottom end. This was cleaned up with the updated power supply & on board regulation. This was consistant across many SOTA's we sold at the time. Sounds like you had a d... |
