Overall I'm very happy with the sound quality I've been getting.
The table looks and sounds great.

Nice to see they have used the best headshell solution out of all the Dual possibilities; this one is decent. The same goes for the wooden plinth, probably similar to that once used for the CS 5000 turntable.

 

OM style cartridges have an weight insert stuffed into their mounting platform - it is that golden brass "triangle" that is removable .

However, Ortofon got the description whether to use or not to use the removable weight wrong in this paper; "normal" arms usually have too much effective mass to be used with the high compliance OM styli; however, that weight plate might still be necessary as most tonearms are not capable of balancing a 2.5 g (+ mounting hardware ) cartridge and still be capable of achieving the correct VTF. Dual arm is light enough to use OM cart in its 5 g version; you should ask if it is capable of balancing a 2.5 g cartridge. In that case, use cartridge compliance/effective mass compatibility calculator, as it may produce an even better result when nused without the weight plate.

Whether you want to do this and have to re-align the cartridge by yourself (or having it done by others) is something only you can decide.

 

Running Stylus 40 at 1.5g VTF is a bit on the high side; I have found OMs (20 and up ) to be the happiest at 13 mN or 1.3g VTF if and when the arm is good enough. It normally provides the best overall combination of performance, yielding very good tracking while allowing for the maximum channel separation. Better OMs can reach about 35 dB of separation between 1- 4 kHz (less below and above that frequency range ) if adjusted correctly; that is a VERY good figure that gets worse by applying too low or too high a VTF. All OM styli I came across were very similar in this regard as well in the overall quality; Ortofon uses what they call "robots" in the production of the MM cartridges, yielding extremely tight tolerances resulting in sample to sample consistency that is second to none in the industry. It is true that they are pricey compared to the on paper similar spec model from the competition - but are justified by their precision; remember, it takes a single play with an uncoath stylus to irreparably damage your record(s). 

 

I agree with other posters that the new Dual is overpriced; the same can be, to a lesser degree, said about Ortofon OM 40 - but the combination should be giving you a very high quality reproduction for years to come. That makes it in the long run a more reasonable choice than it appears in pure $ sense.

Yes, the feet are held in their place by the screws with a Philips head.

 

In out "large" country ( population 2 million ), the people living in the region adjacent to the sea have an interesting expression for similar things - "the same pasta". It IS applicable for SL 12x0 and SL 1500 :D ...

 

There are quite a few options for the "feet" for Technics tables, ranging from squash balls to Isonoe ( and beyond? ) feet  - depending on the size of the piggybank.

Thanks for all the great info, you have been tremendously helpful. I'm going to try the 1.3 avatar settings and see how it sounds. I didn't know that the weight was built into the cart. The table came with the OM10 installed, when it was replaced, I recall seeing the brass weight on the body. I had the Super OM 40 installed by a local hifi shop, so I'm assuming the weight was installed because the tech did not give me any spare parts.

Very time sensitive: is the NAD C340 worth $150? I could get that, sell my receiver and get a schiit modi or just keep my receiver

I've been spinning the new Sgt Pepper Mono lp. Wow, far better than I've ever heard it before.
