Title: Turntables
Post by: rollo on December 03, 2015, 05:54:52 AM
  So what are you using for a TT and phonostage ? running a linn LP12 for mono with grado mono cart.
   For Stereo a Kuzma Stobi S with Stogi S 12"VTA adj arm. Cart now Golden Note. A Miyajima in my near future.
   A Vista phonostage for the Linn and a Loesch & Weisner phono/Pre for stereo. The Loesch needs some repair so was thinking of new phono stage. Looking hard at Miracle audio custom phono. A Parasound or Sim as well.. Would love a Zanden but we need to save some $.
    Looking for a Klyne used but very hard to find. I made a big mistake selling my Klyne SK5A. Live and learn. Hoye !
    Economically fixing the L&W makes sense as it is world class. However the WE 417A tubes are getting rarer and very expensive as we speak. Bummer but life. Then there are 12 more tubaroonies to deal with.  Should I ? Should I not ? What to do.
   Any suggestions ?? I committed to the cart but the PS still up in the air.

In one system I have a restored Technics 1200 Mk2 with a Audio Technica AT150MLX cart. My phono preamp is a U-Turn Pluto Phono preamp.

In my other system I have a modified and restored Thorens TD 125 Mk 2 with a Origin Live RB250 Tonearm with a Ortofon Super OM30 cart. The phono preamp is within a restored Accuphase C200 preamp.

I know this stuff isn't the most expensive or latest gear but I'm happy with what I have got.

VPI Classic II with 10.5 inch JMW are on-the-fly VTA, Benz Micro SMS Glider MOMC cartridge and Wireworld silver cables. i use an throwback Discwasher D'Stat mat because I can not tolerate static. Even if there are better sounding mats I find it is a worthwhile trade off.

Post by: rollo on December 03, 2015, 07:57:08 AM
  Jim there are several anti-static brushes and a mat that is grounded to stand on which eliminates all da static..
   Mapleshades brush is very affective about $35. Mats are available from Edmund Scientific and others that ground to house ground. Great for CD as well. No static is good static.

I do own a zerostat but haven't used it in ages :lol: I also own some type of brush that has a strip of radioactive material that is supposed to reduce static. So I may glow but my LP's will be nice and quiet.  :thumb:

Have a Basis Ovation TT and have used a custom Audience Cabledriver preamp/phono with it. Time to move on from that preamp. Bought a McCormack micro phono, but don't want to spend the $$ for the ultra upgrade any more. So I'm in the market for phono stage as well.  I heard great things about the L and W and would love to score a used Klyne. Names that also come to mind are LKV and Thoeress

I have a VPI Aries clone that was made for me by Hollywood Sound in Florida over a decade ago. It has a Corian plinth and uses a VPI motor and mount and a VPI platter. The platter is rather special. It is a ceramic coated aluminum platter that VPI has been experimenting with, and will sell to you if you ask, but they do not promote it yet.

The arm is a Morch DP-6 with a Lyra Kleos cartridge.

The step up is a modded Hagerman Piccolo into a modded Hagerman Trumpet phono stage.

I have a Trans-Fi Salvation rim drive with Terminator T3 Pro linear tracking arm, Soundsmith Hyperion 2 OCL cartridge.

After a few phono stages, including a Zesto, I've settled on Vinnie Rossi's modular LIO. It has a very nice discrete MM phono stage, with integrated transformers for MC (like the Zesto). There are 2 MC and 1 MM inputs, all remote switchable, as well as a remote control loading option designed by John Chapman. It's an especially nice setup if you have dual arms or multiple tables, e.g. for stereo and mono carts. The remote control loading probably only matters if you are into trying new cartridges, which I don't, as the Hyperion makes me smile.

... and the LIO is definitely da bomb  :thumb:

Micro Seiki BL 111
Kuzma Stogi Reference
Ortofon Blue cart (for now)ardas

Vinyl Song LCR phono stage

this is my son's setup, mine is packed away

The Kuzma is wired direct from the headshell out to the RCA's which I think is a big advantage over using a PIT box. As long as the wire is good. The Kuzma is wired with Cardas which is good, they have a silver option as well.

My other tonearm ( Immedia RPM2) is a much better tonearm than the Kuzma, but it uses the PIT box, which I think is a disadvantage sonically.
But still a better sounding arm, until you move up the Kuzma line to the 4 point. Now we are talking!

While the Micro Seiki is clearly head and shoulder better than his Technics TT, he still loves the automatic features of his Technics, which he uses at school.
No more yelling from me that he is the dead wax!

  It appears our community is well versed in vinyl. Lately really getting into the mono records.
   With the Linn feeding a Vista MM and inexpensive Grado mono cart the sound is just glorious. Using the BSG QOL for mono as it has a mono switch is the key to such great sound.
   I had to show the album cover to Triode Pete as he thought I was pulling his leg. Big open and deep.
   Back to the other TT. The Kuzma arm was ordered with optional Crystal Cable [ silver] The 12" arm has on the fly adjustable VTA adj. For me a wonderful feature. 200Gr, 180Gr, Std, and others need VTA adj. to sound their best. never thought it made such a difference until heard.
   The TT sits on a maple plinth resting in a sand box supported by a Target speaker stand on spikes. It is dead level.
   The upgraded power supply fed by TWL 8 cryo only PC is a well suited cord for this application.
    The Loesch & Weisner Phono/preamp is amongst the best I have owned. had a Klyne S5A, CAT SL1 Sing, Miracle audio, Linn and Audio research SP8. The L&W had the most presence and weight. The SS Phono had better bass and detail and were dead quite. The L&W at times has tube issues and the noise is evident. With good tubes my favorite overall.
   So I guess it only makes sense to repair it. But but it is MM and a step up is required for low output MC. Hoye ! Where  as the SS offerings like the Miracle use opamps in lieu of transformer step up. Brilliant IMO. You need to hear one. However out of business.
   Looking for a Klyne 7 series used but no one gives them up. I'm beginning to realize the benefits of a SS PS over a tubed one and yes visa versa.
   The advantage of SS is quite dead quite to be exact and no outboard step up. It just cannot sound thin. I need meat on the bone and accuracy.
   First the new  Miyajima cart. both mono and stereo. Then it will be phonostage audition time.
   Any other suggestions ??

Noise is most problematic in a phono stage, especially a LOMC one, because of the low signal voltages they have to work with. The phono stage required to boost the output of a LO moving coil car to levels that a preamp is happy to deal with. I only goes to reason that any small amount of noise that sneaks in with the signal will also me magnified many times as well.

What do you think about running a SS phono stage into the line outputs of the L&E pre. This would give you the freedom from noise you desire and will a little bit of luck the tubes of the L&W might still be able to fill in the "Meat on the bone" that you desire. Let each piece do what it does best.


Just a thought.

  Tom actually that is my desire a tubed line stage and SS phono. The Parasound JC3+ is the least expensive class "A" rated PS. A good start.
   The battery powered Dodd is getting a 12V linear power supply in lieu of battery. working on that as we speak. either a custom one by S&G custom sound or a ready made one. Cost is a factor they can be from $125 to $3500.
    The Dodd uses one 6H30 which is a NOS reflector. The other Dodd a 12BH7 [4[ based preamp. The Loesch & Weisner is on hold.
     I really think the Miyajima Shilabe MC [3K] will make the most improvement overall. The Kuzma arm is well engineered and well suited for the new cart. Getting the Nervosa. A good thing.

Charles,
You might want to try your Vista with slagles stepups for the miyajima.
I ran that combo for a while and it was quite good, of course a better fono pre would help even more.
Do what the big boys do in high end analogue and run a MM phono pre and use stepups. Built in gain for a MC is a selling point for sure, but not really the best way to do it. The passive gain created by the transformer is by far the best sounding IMO, the inductor in the cartridge likes to see another inductor boost its signal, whenever caps and resistors are removed from the signal ,,it only gets better IMO.
If slagles stepups are too dear, than try cheaper ones, there are plenty out there......but IMO slagles are some of the best

This may sound goofy but what the hell. Has anyone ever tried perfecting a wind-up version of a TT? Unlike a motor that is used to turn the platter.

Probably have to wind it up after a couple of songs but you lose the motor. If you can wind a watch why not a TT?

Awesome tip on the transformers. What bugs me is the use of nickel in audio. Why do they do this? Here these Transformers are nickelcore. Is that all there is? I do not know I am just asking. I am beginning to believe the problem with solid state is the all the nickel core everything. The wiring, the plating on devices. I think it is horrible for solid state and it is everywhere.  I see the silver but is it silver plated nickel?
Title: Re: Turntables
Post by: richidoo on December 27, 2015, 10:15:55 AM
Werd, nickel alloys (Permalloy) are more magnetically permeable than the standard magnetic core material, silicon steel. Higher magnetic permeability makes the transformer more energy efficient, allowing it to store more magnetic energy before saturating, while also reducing magnetic hysteresis and distortion, and/or reducing the size of the core  and its cost. Permalloy is not the ultimate magnetic core material, but for the cost it is an excellent choice and widely used in the audio industry. Nickel content ranges from 36-80%. Nickel is a toxic metal, so just don't lick it and you'll be fine. ;)

And keep in mind that as the core it is not carrying any signals, it is just the metal that the signal carrying wires are wrapped around. That is very different from using nickel in a connector that the signal will be flowing through.

Title: Re: Turntables
Post by: tmazz on December 27, 2015, 07:21:43 PM
Yes but the current flowing through it will produce a magnetic field. That is the hole theory behind a transformer in the first place. I think the point I was trying to make is that in the case Rich described, although the copper wire is wrapped around the nickel alloy core the current itself is flowing only through the copper wire, so the nickel in the core will not effect the sound in the same way that a nickel plated connector, which the signal current does flow through is known to change the sound.

Permalloy,  trademark of the Western Electric Company for nickel-iron alloys having much higher magnetic permeability than iron alone. It is widely used for fabricating the thin pieces that are laminated to form transformer cores. The proportion of nickel may range from 35 to 90 percent, depending on the properties desired, and is about 78 percent for low-power transformers.

Permalloy is a nickel–iron magnetic alloy, with about 80% nickel and 20% iron content. Invented in 1914 by physicist Gustav Elmen at Bell Telephone Laboratories, it is notable for its very high magnetic permeability, which makes it useful as a magnetic core material in electrical and electronic equipment, and also in magnetic shielding to block magnetic fields. Commercial permalloy alloys typically have relative permeability of around 100,000, compared to several thousand for ordinary steel.

Geez, Western Electric / Bell Labs invented permalloy... shocker!

Originally invented and used to speed-up Trans-Atlantic telegraph communication Four-Fold!

Does this really surprise you Pete? There are not to many things in this hobby that cannot be traced somehow back to research done at Bell Labs.

Iron Sounds  better than nickel. Nickel is the bane of all SS gear. Even in the core of the transformer. What is the typical nickel content found in the core of a block or E core transformer you see in a class A tube? Anyone know the answer to that? I am curious.
