Eminent Technology ET-2 Tonearm Owners



Where are you? What mods have you done ?

I have been using these ET2's for over 9 years now.
I am still figuring them out and learning from them. They can be modified in so many ways. Bruce Thigpen laid down the GENIUS behind this tonearm over 20 years ago. Some of you have owned them for over 20 years !

Tell us your secrets.

New owners – what questions do you have ?

We may even be able to coax Bruce to post here. :^)

There are so many modifications that can be done.

Dressing of the wire with this arm is critical to get optimum sonics along with proper counterweight setup.

Let me start it off.

Please tell us what you have found to be the best wire for the ET-2 tonearm ? One that is pliable/doesn’t crink or curl. Whats the best way of dressing it so it doesn’t impact the arm. Through the spindle - Over the manifold - Below manifold ? What have you come up with ?

The way the ET-2 is normally wired has always been an issue for me when deciding how best to mount it on my TT. Because the tonearm wires are soldered directly to the RCA jacks in the RCA box or mounting plate and the wire is supposed to be fed through a hole in the armboard to create a loop, installing or removing the spindle or manifold requires desoldering the wires and pulling them out of the hole. This is a major PITA and doesn't make installation an easy process.
While I realize that adding additional connections to the audio chain may have negative consequences, this may be balanced against making installation, removal and adjustment an easier process.
My solution was instead of soldering the tonearm wires to the RCA jacks, I instead soldered them to a 4 pin Lemo plug ( the same one used by VPI on their Memorial Tonearms ). I obtained a VPI Tonearm junction box which I mounted to the top of the plinth with Velcro tape. It was then easy to mount and align the mounting post to my armboard without worrying about the manifold-spindle assembly. I then mounted the manifold assembly to the mounting post & aligned it. I plugged the Lemo connector into the junction box & it works fine. I can unplug the Lemo connector & remove the whole manifold assembly in a minute. While there are the additional connections created by using the Lemo connectors, the convenience in mounting & adjusting far outweigh any sonic degradation for me. YMMV.
Bigalt,
I run the wire straight out of the arm tube, looped under the bearing spindle/armlift rod to a teflon block on the the side of the TT (this is mounted behind the lift spindle and halfway along to minimise wire tension when playing. The wire does not enter the bearing spindle at all. I also use a silk insulated copper litz which is much less springy than the plastic/teflon insulated tonearm wires like Cardas etc.
There are no connectors at all between cartridge pins and RCA/phono connectors. If you back the preamp up to the side of the TT you can get the total loom down to around 16".
For maintenance all I have to do is unplug the phono and undo 1 screw holding the teflon block and the whole arm tube comes off complete with wiring loom and cartridge.

The first post on this thread asked about wiring recommendations. Everyone here that has upgraded their wiring arrangement agrees the standard wiring setup is compromised. But lets also understand that everything is the way it is for a reason and to understand why this was done "wiring arrangement", one only need look at the objectives of the particular item in question. So lets take a couple of steps back for a minute.

For the ET2. At the front of the manual. PAGE 3

"It is a uniquely conceived tonearm, designed to be installed on turntables with universal mounts. It can be adapted to both solid mount (direct drive) turntables and spring suspended mount turntables. Its flexibility in many cases allows it to be mounted on many turntables without the need for special hardware. "

The above tells me that this Audio product is not something being made in limited quantities for a select market like many other Audio products. The purpose/objective here is to get it to the most people possible to enjoy it. Numbers sourced from Bruce and documented on this thread, show thousands made. When you distribute a product like this the wiring arrangement needs to satisfy many applications. That means some standard setup, compromises and all, need to be arrived at that satisfies most conditions. The standard wiring setup compromises the ET2 arm in two very different ways.

1) the number of solder connections
2) the wiring arrangement physically affecting the operation (movement) of the arm.

Not even Bruce himself uses the standard wiring arrangement as was clear in his 420 str cartridge review here. He goes straight into the preamp from the cartridge leads. My understanding is all professional reviewers listened to this arm with the standard wiring arrangement. Even in the standard compromised wiring arrangement the arm was very well reviewed.

Bigalt - In the end the important thing.... is that it is very good that you found a solution that works for you.....for now. :^)

For me from personal experience a happy face loop coming off the armtube works best. The full flat plinth presents more challenges to achieve this as you need to elevate the wiring to start; to allow for a happy face loop. The ET2 wiring is a natural for turntable setups that use armboards/pods that are elevated with the platter to allow for a natural happy face loop.
Bigalt -The solution is one of the wireless ( rf not infrared ) remote switched outlets that you can buy online. Press a button on the remote and on goes your compressor. Another press and it's off.....

Bigalt- thanks for the recommendation on the remote. A friend also pm'ed me about this remote upon reading my encounter with the troll. :^)

he sent me this link

I am very sensitive about what I plug into the wall. It all goes back to the main panel. My gut feel is I may be substituting a Troll** for a Gremlin, if I added that device between the pump and the outlet.

True Story
When finishing the 2nd adjacent music room there was this hum (aka Gremlin). I thought it was an amp issue. But when the amp was off it was still there. Go figure... I traced it to the door bell transformer mounted and plugged in along side the ceiling joists. I pulled the wires. Noise went away. Silence between songs.

** I later discovered the identity of the Troll. Our 20 year old son raiding our basement freezer early in the morning on his weekly food rampage. Freezer is plugged into a different outlet separate outlet :^)

While your freezer is plugged into a separate outlet, since it's also in the basement along with your pump it's probably on the same circuit ( both units controlled by the same circuit breaker ). If they're on the same circuit, the refrigerator compressor motor could very easily cause interference with the pump. The remotes ( you can find them on EBay ) are pretty cheap for a one outlet model ) so it wouldn't cost a lot to try one. There is also the X-10 type controllers and appliance modules that send the control signals over the house wiring. They may work as well .
