The Cartridgeman Isolater.


This device get sandwiched between the cartridge and
the arm and could potentially bring down the noise floor
by 3db.
Has anyone here tried it ?
I woud be curious to know about the specific qualitative
influences it might had brought to your sound.
I also wonder what is the principle at work.......

I thought I would take the risk and buy a Cartridge Man Isolator. This is now on my VPI HRX with 12.6 arm. It seems that this product has a lot of skeptics (not many who have actually heard a real one thou) and several positive reviews in the press. Well, in an age of $1800 LP demagnetizers, $150 is not a lot of money to blow I thought. The Australian dealer offered a money back guarantee as I was leaning towards the skeptic’s side.

The new/current isolator model looks quite good with its rounded corners. The isolator material is soft and spongy so with all things related to cartridges, be careful. It is very easy to install the isolator. I agree that the older model looks 3am bush pig ugly.

I put the isolator between my 12.6 arm and the Koetsu Rosewood for 2 main reasons. 1st due to the fact that the rosewood was all ready on my spare arm tube. 2nd I was not that happy with the sound I was getting out of the Rosewood. I thought I would try the isolator before I put the Rosewood up for sale, and then try it on my dyna XV-1 or Clearaudio concerto.
The rosewood had a somewhat bloated ill defined bass, coupled with slight reticence in the treble region and some brightness in the lower treble - overall not very musically convincing. Nice mids thou.

To cut to the chase, in my system the isolator is SUPERB.

It brings a whole new level of relaxed coherence top to bottom. Bass is better defined and controlled, the mids are just super transparent and you can see deeper into the soundstage and the top end is more extended and detailed, but not due to the effect of adding brightness.

This new found relaxed musical presentation does not equate to rolled off highs and slow ponderous bass. Just the opposite in fact, but it just sounds more relaxed and easier to listen to. I can seem to hear instruments start and stop a lot easier (especially noticeable in the whacking of hi hats) which adds tonal meat to the bone as well as allowing you to hear more instrumentation from the performance.

The koetsu now sounds great with pop, rock, blues, jazz, electronica, and alternative. I have not listened to any classical but it sounds great with all music.

Bottom line for me I am no longer selling the Koetsu Rosewood as it now sounds as good - albeit slightly different to my dyna XV-1. Every performance parameter of the Koetsu sounds better and that makes for a musically convincing and enjoyable increase in satisfaction of listening to vinyl.

I am not taking the isolator off the Rosewood it sounds that good now. I don't even want to go back to my dyna XV-1 after living for just over a week with the isolator/rosewood combo.

I will soon buy another Isolator to put onto my dyna XV-1. I just hope the VPI VTA tower can cope with the extra 5.5mm height adjustment. I’ll give some follow up comments after that.

For any VPI owner I would say am must try as in my system it transformed it. For other arms I would give it a try as well as it does what it is claimed to do for my ears.

Five Stars from me and finally something that adds really musical value at a reasonable price.

I would like to hear from other owners to hear their thoughts.

Happy listening
Darren

I know the Koetsu's luv mass. I had a 3gm headshell weight on prior to using the 2gm isolator. The added mass has nothing to do with the big change the isolator brought to the musical equation.

I have also played around with blu tack extensively, on the headshell and strategically placed along the arm tube. It does make a differences but only in certain frequencies and is cartridge dependant. It added bass weight to my system, however also made the tempo more clumsy and lumpy with the koetsu.
The isolator changed all the frequencies for the better and has made the top to bottom coherence so much musically better.

funny I have now received my 2nd isolator to put onto the other arm wand with my dyna xv-1. BUT I am in no hurry to do it. the system is sounding that nice with the isolator/koetsu combo.

Anyway, it is very easy for all of us to be critical of something seemingly simple that many of us can "somewhat replicate" at home.
For me proof is in the listening and the isolator is THE BEST $150 I have ever spent on my hi fi.
With all the money we spend on out hi fi, especially cables and tweaks, the $150 on the isolator is trivial if it works in your system - like it has for me.

If anyone wants to see the new version of the isolator see attached link of it with my Koetsu.

Paul,
I'll try my 103r with an isolator in the next few weeks and advise. If it does the same for the denon that it did for my Koetsu the denon will sound sensational. But, then again it may not.
How bout you try one on your jubilee and let me know. I don't want to take it off my Linn / naim arm as the naim arm is too small for the isolator,
Darren

At least I have got you thinking. THat is my only point in this excercise. better than guys passing negative comments who have not heard the device.
If you send me your raven, tomearm and Jade, I will gladly test the isolator :)

Yea, I know what you mean re not having enuf time to listen to cartridges. If you have more cartridges than arm's, some cart's sit in their box for ages. that is happening with my 104r at the moment as well.

Did u ever upgrade your VTL 7.5 to V2?? better sounding??

cheers
Hi coneflap

I too was a skeptic, until that is after I actually listened to the isolator. I take it that you have not, so you are just "ranting" which is OK in this free democracy. The made from "micro spiralex" came from the reviewer at Stereo Times.

In the spec sheet that comes with the isolator it states the construction is " 2 x 0.2mm stainless steel plates and a closed cell, cross linked ethylene copolymer structure. cartridge fixing : high specification 3M glue film".

If you google " ethylene copolymer" you get 1,240,000 hits. Does that make you feel better??

I would assume the main reason why the isolator works is that is isolates to some extent non audio frequency resonances etc from the LP to the carridge but stops it going up the arm and from the arm itself to stop it going back into the cartridge. Sounds reasonable to me with all the other isolation devices that are sold for all other parts of the audio chain.

Tubes measure poorly compared to SS, however most of the time they sound a lot more musical - how do you explain that?

cheers
Oh come on Darren

I don't dissagree with you. But $150 bucks is chicked feed to what you have invested in your system. It would be a bit of fun, you don't even need to disconnect your cartridge leads. And you may see an improvement :)

What arms do you have these days??
Hi Paul

Yes thinking about the jubilee, it would probably be a waste of time. I forgot about the ridge!!.
I am like you re the vertical height with my dyna XV-1. I think I will be close to teh top of my VTA tower.
If I don't have enough play, I'll put it on the denon 103r after that.

Yes I got it from Brian at decibelhifi. he seems like a nice guy.

I will be interested in seeing how it goes with a graham arm.
