Upgrading from Dual 704 to Technics 1300G – Worth it for Sound Quality?

Why does the Dual limit your options in cartridges? That would be a good reason to switch, as changing cartridges can make a lot bigger difference than changing turntables, as I recently discovered when replacing a Clearaudio Charisma II MM with a Hana Umami Red MC (though that also cost almost twice as much) on my 1200G. 

The Dual has a very light tonearm, which limits your choice of cartridges. 

Only you can decide if it is worth it, but there is no question that the Technics is superior to the Dual in every possible sense.  It will measure better and sound better and be far more flexible.  I have owned my GAE since 2016, it sits right next to a TT that costs over 5x as much and yet it is more often than not the one I turn to for most of my listening.  These are wonderful TTs and you would not regret the decision to acquire one.

Thanks for your reply. This convinces me even more to go ahead with the purchase. There’s currently a great offer for €2,299.

That Dual is almost 50 years old. Go with that Technics!
