...The 1200 isn't really a hifi turntable..and it was never seriously marketed as one...
While I feel the stock Technics SL1200MK2 isn't a perfect table, I'd argue this point as incorrect.
And so would Technics, as they clearly stated the SL1200 series was designed for audiophile use, and proved "...a strong favourite among audio purists, amateur and professional..."- Of course, that's their marketing copy, so maybe a point perhaps arguable. Or not.
But alas, you are on mark about the popularity in discos- "...particularly popular in discos because of its rugged construction, easy handling, high torque and good immunity to feedback...."
...It's a DJ turntable designed for people whose hearing is already damaged, and who are likely to be operating it while 'chemically enhanced' - hence it's tendency towards a 'tizz-boom' sound if you let it and being built like a brick outhouse so it doesn't break when you fall over on it...
For some reason, I really can't picture the Technics engineers sitting around, with sole intention to design a table specifically to reach goals such as 1) build it for those with pre-existing hearing damage 2) ease of use under owners with a predisposition for chemical dependency, and 3) people with a tendency to commonly fall on their turntables.
UK's HiFi World would disagree too, with this excerpt discussing the stock Technics SL1200MK2-
"...Having spent many years in love with a Rega Planar 3 I found myself borrowing a Technics SL-1200 Direct Drive turntable, fitted with a decent Goldring G1042 cartridge. I was expecting a deeply unpleasant listening experience compared to my reference Rega, let alone my "main" Mitchell Or be. I duly cued up my copy of Inner City's "Good Life", sat back and was amazed….in some respects it seemed inexplicably not just better than my Rega, but better than my Mitchell too!..."
Admittedly, perhaps a bit too jubilant a review.
Also in your favor, UKs Tone Audio prefers the Rega P3 over the SL1200MK2, saying:
"...I must confess that while my journey in HiFi started with a Technics SL1200 about 35 years ago, I quickly got caught up in being a proper audiophile and traded that table in for a belt-drive Rega Planar 3. To be fair to the Rega, I still prefer the sound of a P3 to the sound of a stock Technics SL-1200..."
But back to HiFi World- and also in your corner- they concur they prefer the Rega RB-250 arm over the stock Technics arm- a testament to Roy Gandy's RB250, RB-300 and above arm.
"...I fitted a beautifully rebuilt (by Audio Origami) Rega RB-250 to a SL-1200, plus a SoundDeadSteel Isoplatmat platter mat and Isnoe isolation feet, The result was music to my ears..."
And you'll find me in agreement- an SL1200MK2 in stock form has a few shortcomings, but a modded SL1200MK2, with these issues addressed, can be something special.
"...The fundamentals of the Technics SL1200 are excellent, and the more it's modded, the more they shine..."
Again, let's step back to Tone Audio, discussing a fully modded SL1200MK2 from UK's Dave Cowley- these mods not as budget conscious as a mat and Rega arm swap, these mods including an arm upgrade to an SME 309 for one, power supply, bearing, and a few other goodies, and ringing in at a final total cost of triple the stock technics, at $2000-
"The Sound – Glorious!
Yes, you heard right; I’m gloating about the sound of an SL-1200."
and-
"I’ve had the opportunity to listen to a lot of turntables in the $2,000 - $3,000 range from Rega, VPI, Pro-Ject, Music Hall, etc., and for my money, this one is the one to beat..."
It is heavily suggested here by Tone Audio it takes the $5000 Rega P9/RB-1000 and Raven Two to top the fully modified $2000 Technics-
"...Would I give up my Rega P9/RB 1000 or Raven TWO with SME 309 for this table? No, it’s not that good, but it’s so damn good for $2,000, paired up with your favorite $900 cartridge, that you may not ever need to spend more money on a turntable unless you have a mega system. This truly is a magic combination, being much more than the sum of its parts..."
My point is- the Technics SL1200MK2 is not perfect, but can be modified cheaply to costly, for performance gains at each price point comfortable to the owner.
These pricepoints/mods start at under $100 for better RCAs and tone arm wire (if you do it yourself) and tone arm dampening mods, to an additional $300-$600 for a Jelco, Sumiko, Audioquest, Rega or other arm and including arm board, to the $200-$300 bearing mods, to the $230-$450 power supply, to the uber-mod- the $700-$900 used market SME 309 arm.
PS- I always enjoy listening to the P3 at my friend's place- especially with the external PSU.:thmbsp:
NOTE- that's an approx. $1475 table to put in perspective with the stock and modded Technics tables, $650 stock to $2000 fully loaded.
