New Technics turntables

best-groove, If you can re-interpret the following sentence fragment, I might have a better idea of what you're trying to say: "...has alternating the cartridges he possesses on both and not he noticed better differences passing from the SP10 vs 1200 GR while with different arms."  

What was your friend's thinking as regards the stethoscope experiment? (I'm a doctor, too.)  Listening to music using a pair of familiar speakers driven by a known amplifier is the test, assuming neither turntable is grossly malfunctioning.  And yes, one must do the comparison with the same tonearm and cartridge on both turntables, for the results to have meaning. I realize that may be inconvenient if not impossible, because the GR tonearm is fixed.

Finally, I am not at all concerned about the future repairability of any of my already ancient DD turntables.  They are all beautifully made out of materials that will never degrade.  The only moving part that wears is the bearing, and bearings can always be renewed.  The motor and associated electronics are made of parts that can be sourced without recourse to the company that originally built the turntables.  What I would worry about is the continued availability of smart EEs who understand how these things work and are willing to fix them.

So, the consensus is to buy the 1200 GR even though you don’t want or need DJ features?

The ONLY "dj feature" is pitch control fader, which is actually a very nice feature even for audiophiles. If you don’t want to change a pitch of music just press the button to bypass it. No harm for audiophile playback.

When a turntable designed for use in the club with high pressure of sound (very loud sound system, deep bass from huge subwoofers near the stage with turntables) is must be a good bonus, becase isolation of the plinth and platter to avoid bass feedback must be superior.  

Any other "DJ feature" is a myth.

listened to both turntables with the stethoscope, said that both very silent engines very similar to each other, indistinguishable.

What I was trying to explain is that by moving his cartridges from the SP10II to 1200GR after more auditions he has not noticed substantial differences stating that neither of the two turntables is superior to the other .... then it can be argued that they are very questionable tests if the tonearms do not they are the same, or the cables are not the same, etcetera but this was his thought and I can not discuss his word.
Who wants the new product can easily do it, will have a good turntable equal to the SP 10II only much more modern and current.

I tried to explain that for SP 10II there are always spare parts, he knows that I restore the Technics (I own 6 in the my private collection and differents spare parts) and in case of problems on his turntable I could help him in case of problems but he did not want to listen to me... he wanted to change turntables without suffering low quality.

Sorry for my bad english ... I hope you understood my speech

What if you had a 1200 GR and a 1500C next to each other with identical phono cartridges, would one turntable better the other?

GR must be better than 1500c

The GR is more expensive without cart and phono stage which is included in the lower price semi-automatic 1500c
