What preamp will the power amp be mated with (in the case of the 509)? Details of other system components and musical tastes, room size etc. may help inmates advise you.The Turnberrys are very sensitive (Tannoy quote 93dB) so is there a particular need for circa 100w /channel? As the Zanden specifications give no distortion figures even though power output is shown as 90 watts, 100 watts maximum, I would query the actual output as judged by conventional standards.
I don't know the prices that you pay in India but here (UK), the Zanden 6000 is twice the price of the EAR 509 which would be a significant matter when making a choice, at least for me. However the two products are not strictly comparable the Zanden 6000 being described as an integrated amp and the EAR 509 being a pair of mono power amps.
The new 509 is not just a simple remake of its predecessor having a smaller chassis and an LED display for tube biasing which I don't recall the earlier ones having (I may be wrong). It certainly benefits from a 30 year history of manufacture and the lessons learnt by EAR Yoshino over that time, particularly for matters such as reliability.

I use a tricked out Garrard 301 and Nantais Reference Lenco as source. The phono stage is a 47 Labs phonocube. Preamp currently is a Klyne System 7. I may go with a tube preamp if required.
I listen to almost every variety of music except Opera. I prefer my system to be open, dynamic and tonally correct. PRAT has to be spot on else I lose connection with music quickly.
Even though Turnberry is rated at 93db I have observed that they like to be driven and controlled. Small amps quickly lose steam with this speaker especially controlling the 10" driver. I am not a soft listener either. Hence the amp has to be totally in control while doing 95-100 db SPLs.
100 watts seems to be sweet spot in my opinion.
Zanden is in the run up because there are couple of used ones available. It can be used as a power amp too. If it turns out to be a really good as an integrated amp then I can sell of my preamp.
The primary reason I am interested in the 509 is its legacy as a top quality studio amplifier and that too using vacuum tubes. I anyway do not want my amp to impose its signature as much as possible and it is always better to err on the tube side than SS side.

Then the 509 might be your best choice of the two. But I think that mating it with , say, an EAR 868 ( OK, my choice) may suit you better than with a SS pre-amp. Then again the selection of tubes is another variable.

The 509 MkII's also had the LED for biasing. Much easier to work with than the Mk I's. Had the MkII's for several years. Did not hear that as a bright speaker, at all. Powered GamuT L5s and sounded very nice.
Power is not the issue with sensitive speakers; system gain is. Many high sensitivity speakers perform better with more power from SS amps. Some mfrs make low-gain amps (although I only know of Audio Note UK).
