Diary of Linn LP 12

18 February 2007 - Mounting of Ittok III tonearm on LP 12

¡@

With the help of Master Linn Yu and Edmund, the Ittok III finally takes its place on the LP 12.  It is a beautiful match.  Actually the Ittok III looks more beautiful than the Ekos because of its silver finish.

Much of the installation procedure is the same as that of the SME IV so I won't repeat further.  However, we spent much time in securing  the P clip that locks the phono cable to the subchassis.  The locking must be very tight.

The plinth is resting on four 2" ebony wood blocks obtainable from hifi encore. They are specially made for the LP 12 contributing a rich and stable sound stage. ¡@ The adjustment of tracking force and anti-skating is quite accurate for this copy of Ittok III. It also passes the paper test for the bearing sensibility.

I didn't use a Linn cartridge because I don't want to be struck with one choice. I always prefer Ortofon for its musicality.  The one I use is the Rohmann. The MC5000 may be my next target. ¡@ The Rohmann comes with PCOCC copper wires for connecting to the tonearm.  The wires are too thick and not easy to work with.

The Ittok III has some significant improvement over the Ittok II. The entire arm is bonded to the turret and the headshell with epoxy while the Ittok II is secured with six screws.  ¡@ The shape of the headshell is also redesigned.  Actually it is the same as the Ekos.

The hercules PSU provides 33 and 45 rpm speed from the power switch.  Red indicates 33 rpm. ¡@ And blue indicates 45 rpm.  I highly recommend this 3rd party PSU which is the 2nd best to the expensive original Lingo PSU.

I use the T30 transformer and set the impedance to 24 ohm.  It is the best match setting from my listening.  The T30 is resting on 4 Audiotechica soft footings. It was a surprising discovery.  Try it out and you don't want to remove them. ¡@ We use original Linn phono cable initially but after a few cuts of music we switched  to a Kimber Kable TAK (the golden one in the photo). The sound is an immediate improvement with much better detail and more dynamic. The T30 to EAR 834P is connected with a pair of Monster cables for the time being.

TThe delux EAR 834P.  My friend has changed 1 Mullard and 2 Brimar tubes for me.  So far they are sounding much better than the original Russian tubes. ¡@ The very thick chrome and golden front plate of the EAR 834P is a beauty to behold. 
¡@ ¡@ ¡@

I don't have tube preamp and power amp as I don't have the knowledge to work with tubes.  Here is the Mark Levinson 380S preamp.  So far so good. I don't have plan to replace it yet. ¡@ The power amp is the Mark Levinson 334.  It is reliable and sounding quite neutral as well as providing the power where it is needed.  Output is 250W which is needed for my B+W N802 speakers.
¡@ ¡@ ¡@
¡@
The speakers are B+W N802 having been running for over 6 years now.  I think they are beginning to mellow well so no plan to change yet. ¡@ My AV entertainment den.  It is reasonably spacious - 13' X 24'

With this episode, my LP12 diary comes to a recess.  Thanks to all friends who walked the miles with me.   My thanks go specially to Master Linn Yu, Edmond and Dr. Lee for providing invaluable information and help to convert me into a Linn follower.  I would also like to thank the friend in UK who sold this excellent LP12 and the rare to find Ittok III arm to me.   As I predicted, the Ittok III goes well with the LP12 as the perfect match made for each other.  Putting them together is what I should do to these beautifully engineered products. 

Now some feedback from the audition party of this combo.  After hours of setup work, when the first music note was sounded, it was however not a full house over joy.  There wasn't the dynamic extension especially in the upper end and the mid range seemed a bit stiff while the characteristic Linn tempo wasn't evident enough too. Nevertheless, the potential could be felt with presence of smooth flow of rich details.   We didn't doubt the TT setup but suspected that somewhere in the link, something could have taken away that dynamic sweetness.  We then changed the weakest link by replacing the original Linn phono cable by the Kimber Kable Tak cable which immediately regained a lot of lost treble.  A few more moments of run-in seemed to be opening up more.  As always, just when the sound was beginning to improve, the party had to end because everybody had to rush back for preparation of the new year.

When the setup party ended, I had a hard look at the combo and the placement of the cables.    I disconnected all the cables, had a check up from underside of the LP 12, tightened up all the screws again, then I moved the T30 step up transformer away from the CD player to keep it from noise interference and placed it next to the EAR 834P phono amp.  I had to change to a pair of Monster Cable for connecting it to the 834P because the previous pair was too stiff to be bended.  The Monster cables are stand-in for the moment.  I am thinking of replacing with another pair of Monster cable made specially for phono signal but I need to change the DIN plug to RCA connectors.  I am sure that this pair would contribute to some further improvement.  The biggest discovery of the day however was when I place the T30 step-up transformer on 4 Audiotechnica soft supports, the upper end immediately opened up with air and each musical note became effortlessly audible.  The proportion of the instruments was also much improved.  I guess the step up transformer apart from avoidance of noise interference should also be protected from unwanted resonance as far as possible.   Master Linn Yu also reminded me that the 4 little cartridge wires need to be run in as they were brand new.  So after over 10 hours of running, it is gradually replacing stiffness with mellowed sweetness.

Master Linn Yu of course would not give up convincing me to get a brand new LP 12 and Ekos arm.  He was right in that it is failure proof to get the beloved Linn sound. He wasn't as pervasive on Linn cartridge but may be it is his next line of preaching.   But considering the escalating price of the brand new LP 12 and the Ekos arm, I think I have got a good deal for this nice 2nd hand set.  For the moment, I think I'll stay with this nostalgic set being an old Linn chassis with upgraded rosewood plinth, modernized with the Cirkus bearing and a brand new motor, then mounting with the latest out-of-production  Ittok III arm which is said to perform nearly as good as the Ekos I.  They all match together as the perfect combo.  The cartridge I am using for the time being is the Ortofon Rohammn.  I have always loved Ortofon for its musicality and may be later in the year, I'll consider its top of the line MC5000.  Afterall, it's not going to cost me an arm and a leg when compared with the other high-end cartridges. 

So, until then, this diary will come to a recess and thank you all again for joining me.

Wish every hifi friend many many hours of joyful listening in the year of the Boar.
