| Eminent Technology ET-2 Tonearm Owners Thekong.It should be no surprise that the arm weighs in at that figure or even higher with the heavier counterweights. It is neccessary for it to perform well with low compliance carts. This provided that appropriate damping is applied. Lead out w... | |
| Eminent Technology ET-2 Tonearm Owners Thekong.It will be interesting to read about your findings. Do you have the horizontal effective mass figure for the 6000? Can you please post this if you have it. My experience with adding weight is that you should be targeting a horiz resonance ... | |
| Eminent Technology ET-2 Tonearm Owners My apologies in advance if this topic has already been covered in the thread. Too many posts to read thru.Twenty years ago I made a oil damping trough for the then standard ET2, mounted on a Goldmund Studio. Mixed results, which could have been as... | |
| Eminent Technology ET-2 Tonearm Owners Chris.Good to read your findings on the gooseneck. They parallel what I heard when making the change here. You can expect more of the same when we find a way to bypass the o'rings in the manifold, along with a satisfying jump in dynamic contrast a... | |
| Eminent Technology ET-2 Tonearm Owners Chris.Glad that you like the aluminium goose neck. I designed it to be as stiff as possible. The tighter fit into the wand and spindle is deliberate. Also it is made from the same grade of aluminium as the spindle, 6061 T6. This to minimise the di... | |
| Eminent Technology ET-2 Tonearm Owners Maths and Physics.StiffnessMany years ago I remember reading an audio magazine which tested the rigidity of the ET2 bearing. It may have been Martin Colloms, but I can't be sure. This was done, again from memory, where accelerometrs were used and ... | |
| Eminent Technology ET-2 Tonearm Owners Maths and Physics.A few days back I wrote that the res freq of the arm was proportional to the square root of the inverse of the mass and stated that there was a discrepency in the ET2/2.5 comparitive figures that Chris had posted. This because th... | |
| Eminent Technology ET-2 Tonearm Owners Chris,This is strange.For the example BT uses in the manual, pages 48 and 49. The res freq for the ET2 with a 30cu cart we get around 4.7 hz.For the ET2.5, assuming it is only 9 gms heavier the res freq with the same cart would drop to around 4.2 ... | |
| Eminent Technology ET-2 Tonearm Owners Lets look at things again.I am officially retracting my retraction to Thekong regarding the ET2.5. Here is why.When I realised my obvious mistake in thinking he was going to place a rigid CW arm on an ET2, when in fact he was proposing to use one ... | |
| Eminent Technology ET-2 Tonearm Owners Double posts and thread ghosts of the past. How does that happen?Chris.It is good to see that analogue gear is holding its price. Maybe the current trend of interest will continue. My sons and their friends are keen to spin records. A welcome chan... | |

| Eminent Technology ET-2 Tonearm Owners Frogman.20 years! It gets scary when you start thinking back doesn't it?I also have a continuous run to the pre but put it inside purely for cosmetic reasons. My thoughts would be to route it such that it stands off from the wand a little. In theo... | |
| Eminent Technology ET-2 Tonearm Owners Ketchup and Frogman.Thanks for the pics.Can either of you describe the changes with the wire outside. I would expect a more lively, detailed, precise presentation. Seeing the manifold like that reminded me of the shim/grub screw set up. Has any on... | |
| Eminent Technology ET-2 Tonearm Owners Frogman.Excellent! You have inspired me to do this with mine.Thanks for the feedback. | |
| Eminent Technology ET-2 Tonearm Owners Hi, I hope that you all had a great Easter break with Family and Friends.Chris. I don't have any first hand experience with arm pods. They tend to go against the grain so to speak, in the quest for absolute dimensional stability between platter an... |
