Ready to try vinyl

Dear friends: I think that Johnnantais is right in many ways and I agree with him in many issues.

His Gallileo, Bacon, etcc references, are a way to dramatize a fact that the 99% of the people " can't see it " or does not " want to see it ".

Opalchip do serious statements about what exactly is the job of a TT for to know what can we expect from a TT : +++++ " What exactly does a turntable do? It's a platter spun by a motor that we put a record on. The ABSOLUTE BEST thing it can do is turn at an accurate, highly constant 33rpm and not impart any vibration to the lp. It cannot "add" anything positive to the playback. " +++++

Any one of you have to agree with those statements, especially: ACCURATE AND HIGHLY CONSTANT SPEED ( 33/45rpm in the short and long run ).

Here the idler/DD TT's beats any belt drive design ( including the Walker ). I own four belt drive TTs, three SP 10MK2, two DP80s and one DP75 Denon's. In the past I was owner of: SP10MK3 and a Denon DP 100 ( please don't ask why I don't own today these two TTs. I don't want to remember it ).

The idler/DD servo TTs are dead steady on the rpm issue. The motor in the DD TT is really a tour de force, at least in the DD models that I own.

The pitch in the music reproduction in a home audio system is the most critical subject for a right musical appreciation. Any small variation in the TT speed change the pitch and change totally what we are hearing.

The problem in the belt drive systems is in the belt drive it self ( not in the small motors that are using ), all kind of belt drive materials: kevlar, nylon, silk, rubber, etc., have the tendency to stretch ( every single second that are in use ), is this tendency to stetch what do almost impossible to mantain a constant speed. The DD drive servo TTs don't have to fight with this critical issue and don't have that little speed variations that the belt drive have: especially in the short run, that is where really is important. Now, it is not only the stretch tendency on the belt drive system what is a critical issue there are other critical issues in a belt drive systems, like: changes in the room temperature, changes in the room humidity, the pulley and platter friction with the belt, the pulley/platter build imperfections, etc...

This single subject: " ACCURATE AND HIGHLY CONSTANT SPEED ", ( where everything the same ) do the difference between a belt drive system against a DD system, where the DD system beats the belt drive system.

Johnnantais don't have to go so far away: the best TT system is the Rockpor Sirius, this 70K+ " baby " use a DD system: wonder why? Don't you think that if the " experts belt drive system " was the better Rockport would had choose it?

The three belt drive systems TTs that are in my current audio system are very good on the speed issue but aren't perfect: I'm checking every day and some days after/before every listen record the speed variation.

There are many issues of the why's many of us and all the " reviewers/experts " are using belt drive systems: but this situation is only circunstantial and does not means that the belt drive system is better than the direct drive system, because it's not.

Raul, although I frequently agree with your writings, we are very far apart on this topic.

Having owned multiple direct drive and idler wheel drive design turntables, I am aware of their strengths. No question their speed accuracy is uncanny, but there are a few exquisitely engineered belt drive turntables that overcome this technical obstacle.

The Walker represents the pinnacle of this engineering, maintaining flawless speed accuracy and control that equals the idler wheel models while maintaining such virtues as adjustable air suspension system, air bearing non-resonant platter and integrated linear tracking arm with adjustable pressure air bearing.

Understand, I was one of the first to compliment Johnnantais and throw my support behind him when his Lenco thread was begun. In spite of my admiration of the Lenco and Garrard idler wheel designs, there is no contest between these and the Walker.

We can banter back and forth on this all day, so I will just say that you're entitled to your opinion and that I don't share your view. This, based on my own experimentation over the years with hundreds of turntables.

How many Mexican pesos is a Walker?

Dear Albert: I think that I don't explain the speed issue in a right way.

+++++ " : ACCURATE AND HIGHLY CONSTANT SPEED ( 33/45rpm in the short and long run ).

Here the idler/DD TT's beats any belt drive design ( including the Walker ). " +++++

If I can remember the Walker speed accuracy is 0.002%: a really splendid figure, but the SP 10M2 is half that of the Walker: 0.001% and the SP 10MK3 is only 0.0001%.

I agree with you on your statement: +++++ " The Walker represents the pinnacle of this engineering... " +++++

But that is not the point. My point is very simple:

" A Walker DD system beats a Walker belt drive system ", if only for the better speed accuracy of the DD design.

Albert, this is part of what I already post and maybe you loose to read:

+++++ " This single subject: " ACCURATE AND HIGHLY CONSTANT SPEED ", ( where everything the same ) do the difference between a belt drive system against a DD system, where the DD system beats the belt drive system. " +++++.
You can note: ( where everything the same ).
Your statement that the Walker is superior to a standard Lenco is out of place: of course that is superior.

I know that I don't have your wide experience with hundreds of TTs ( like you say ) and my reference to Walker TT was not against the Walker or against any Walker owner like you. As I told you my point is a simple one.

Regards and enjoy the music.

OK then, your comments are based on specification posted by Technics, builder of the SP10 MK3.

If that number is correct, perhaps speed accuracy is not as important as it seems.

Or perhaps the whole turntable and arm package is more important than just speed accuracy, assuming Technics has stated speed accuracy properly.

Many pieces of equipment that are excellent on paper do not necessarily sound excellent . For instance, Technics also builds some integrated amplifiers that have amazingly low distortion specification but sound pretty dismal against tube based amps from Atma-Sphere, VTL or Audio Research, all of which have higher distortion numbers.

I have owned several direct drive tables and auditioned the Technics hundreds of times when I sold them. I was never impressed enough with their performance to consider them for state of the art playback. Of course I was going by sound, not the specification sheet.
